Enterprise Server 3.11 release notes

HIGH: An attacker could bypass SAML single sign-on (SSO) authentication with the optional encrypted assertions feature, allowing unauthorized provisioning of users and access to the instance, by exploiting an improper verification of cryptographic signatures vulnerability in GitHub Enterprise Server. This is a follow up fix for CVE-2024-9487 to further harden the encrypted assertions feature against this type of attack. Please note that encrypted assertions are not enabled by default. Instances not utilizing SAML SSO, or utilizing SAML SSO authentication without encrypted assertions, are not impacted. Additionally, an attacker would require direct network access as well as a signed SAML response or metadata document to exploit this vulnerability.

HIGH: An attacker with Enterprise Administrator access to the GitHub Enterprise Server instance could escalate privileges to SSH root access. This is achieved by exploiting the pre-receive hook environment to bypass symlink checks in the ghe-firejail path and execute malicious scripts. GitHub has requested CVE ID CVE-2024-10007 for this vulnerability, which was reported via the GitHub Bug Bounty program. [Updated: 2024-11-07]

This error message mbind: Operation not permitted was repeatedly showing in the /var/log/mysql/mysql.err MySQL logs.

When saving settings in the Management Console, the configuration run would stop if the enterprise-manage process was restarted.

A missing configuration value prevented Dependabot from creating group update pull requests.

On an instance with GitHub Actions enabled, some maintenance tasks could fail due to incomplete upgrade steps during previous upgrades to new releases of GitHub Enterprise Server.

The initial setup certificate generation in AWS took longer than expected due to fallback to private IPs. The time for this fallback has been reduced.

If the primary instance was unreachable, running ghe-repl-stop --force on a replica would fail during the config apply run.

When restoring from a backup, repositories that had been deleted in the last 90 days were not completely restored.

Restoring Git repositories using backup-utils occasionally failed.

Some customers upgrading from 3.11 to 3.13 may experience issues with undecryptable records during the upgrade. This issue has now been resolved. We recommend you read "Undecryptable records."

For instances deployed on AWS, the default settings for Chrony NTP synchronization have been aligned with AWS's suggested default configurations.

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. See "Résolution des problèmes d’accès à la console de gestion."

The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn't required, and outputs an error instead of a warning.

On an instance hosted in AWS, system time may lose synchronization with Amazon's servers after an administrator reboots the instance.

On an instance with the HTTP X-Forwarded-For header configured for use behind a load balancer, all client IP addresses in the instance's audit log erroneously appear as 127.0.0.1.

In GitHub Enterprise Server 3.10 and later, the requirements for TLS security levels have changed due to an upgrade to containers in the underlying OS. On an instance with GitHub Actions enabled and a custom TLS certificate, users may experience disruptions with workflow runs if the TLS certificate uses weak encryption. Workflow runs will not trigger, and the following error message will appear in system logs for babeld.

CA certificate key too weak

To resolve this issue, confirm that your certificate complies with level 2 of the OpenSSL security specification. For more information, see SSL_CTX_set_security_level in the OpenSSL docs. For more information about reviewing your instance's logs, see "À propos des journaux système."

If the error appears in babeld logs because your TLS certificate does not comply with level 2 of the specification, you must create and upload a new certificate with stronger security before you upgrade to GitHub Enterprise Server 3.10 or later. For more information, see "Configuration de TLS."

In some situations, large .adoc files stored in a repository do not render properly in the web UI. The raw contents are still available to view as plaintext.

The HAProxy version has been updated in this release. You may encounter elevated error rates when HAProxy is upgraded as part of a hotpatch upgrade to a GitHub Enterprise Server instance. These elevated error rates should resolve within 5 minutes of the hotpatch being applied.

Please note, when performing a hotpatch upgrade to GitHub Enterprise Server version 3.11.1 or higher you will encounter this known issue only if you are hotpatching from GitHub Enterprise Server version 3.11.0.

Repositories originally imported using ghe-migrator will not correctly track GitHub Advanced Security contributions.

The reply.[HOSTNAME] subdomain is falsely always displaying as having no SSL and DNS record, when testing the domain settings via the Management Console without subdomain isolation.

Admin stats REST API endpoints may timeout on appliances with many users or repositories. Retrying the request until data is returned is advised.

If a hotpatch upgrade requires the haproxy-frontend service to be restarted, the restart will hang if there are existing long-lived connections, such as browser web sockets or Git operations. No new connections will be accepted for up to 5 minutes. Any existing unfinished connections at this time will be disconnected.

When restoring from a backup snapshot, a large number of mapper_parsing_exception errors may be displayed.

Services may respond with a 503 status due to an out of date haproxy configuration. This can usually be resolved with a ghe-config-apply run.

MEDIUM: Malicious URLs for SVG assets provided information about a victim user who clicked the URL, allowing an attacker to retrieve metadata belonging to the user and use it to generate a convincing phishing page. This required the attacker to upload malicious SVGs and phish a victim user to click the URL for the uploaded asset. GitHub has requested CVE ID CVE-2024-9539. This vulnerability was reported via the GitHub Bug Bounty program.

HIGH: An attacker could bypass SAML single sign-on (SSO) authentication with the optional encrypted assertions feature, allowing unauthorized provisioning of users and access to the instance, by exploiting an improper verification of cryptographic signatures vulnerability in GitHub Enterprise Server. This was a regression introduced as part of follow-up remediation from CVE-2024-4985, which resulted in a new variant of the vulnerability. Please note that encrypted assertions are not enabled by default. Instances not utilizing SAML SSO, or utilizing SAML SSO authentication without encrypted assertions, are not impacted. Additionally, an attacker would require direct network access as well as a signed SAML response or metadata document. GitHub has requested CVE ID CVE-2024-9487. This vulnerability was reported via the GitHub Bug Bounty program.

HAProxy reloading was failure prone, which could lead to failed Git operations. This reloading process has been replaced with a more resilient Systemd process.

An unhandled nil value when configuring Actions storage with AWS S3 via OIDC configuration in the terminal could cause an error.

On an instance with secret scanning enabled, the custom pattern page would not load because dry run results were tied to a deleted repository.

The "List teams" API endpoint returned duplicate results when paginating.

A model with no URL could cause a ghe-migrator import to fail.

Restore could fail when restoring MySQL using backup-utils.

Pre-receive hook environments can use the clone3() system call.

The creation, deletion, or change in visibility of a gist has been added to the audit log.

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "Résolution des problèmes d’accès à la console de gestion."

Services may respond with a 503 status due to an out of date haproxy configuration. This can usually be resolved with a ghe-config-apply run.

MEDIUM: An attacker could steal sensitive information by exploiting a Cross-Site Scripting vulnerability in the repository transfer feature. This exploitation would require social engineering. GitHub has requested CVE ID CVE-2024-8770 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could push a commit with changes to a workflow using a PAT or OAuth app that lacks the appropriate workflow scope by pushing a triple-nested tag pointing at the associated commit. GitHub has requested CVE ID CVE-2024-8263 for this vulnerability, which was reported via the GitHub Bug Bounty program.

HIGH: A GitHub App installed in organizations could upgrade some permissions from read to write access without approval from an organization administrator. An attacker would require an account with administrator access to install a malicious GitHub App. GitHub has requested CVE ID CVE-2024-8810 for this vulnerability, which was reported via the GitHub Bug Bounty Program. [Updated: 2024-11-07]

For instances deployed on AWS with IMDSv2 enforced, fallback to private IPs was not successful.

A config apply run may not have been properly applied due to calls being made to Nomad before it was ready to accept connections. When this occurred, the Error querying agent info: failed querying self endpoint: Get "http://127.0.0.1:4646/v1/agent/self" error was written to the /data/user/common/ghe-config.log file.

ghe-storage-find was sometimes unable to identify a data disk.

After upgrading the relevant GHES version, the resolvconf service failed to start due to a missing directory.

When configuring a high availability replica and during the database seeding of a MySQL replica node, restarting the nomad service could time out. Consequently, when MySQL replication attempted to start an error was reported, and setting up replication failed.

Placing Nomad jobs would not allow retries in cases when Nomad wasn't available yet.

On an instance in a cluster configuration, the ghe-cluster-status command returned an error if a soft-deleted repository had a checksum mismatch.

Some repositories could miss spokes information after restoring in a clustering topology due to unrescued exceptions.

Fixes and improvements for the git core module.

The CommandPalette component no longer displays repository information on 404 pages, preventing the leakage of private repository information for users without access.

Custom links to other repositories displayed incorrect breadcrumbs.

When a GitHub App installation had all repositories installed individually, it was not possible to remove the repositories from the selection.

Some custom pattern matches were incorrectly filtered during post-scan filtering. You may want to edit and republish your custom patterns. You can manually republish custom patterns with the following command: ghe-secret-scanning jobs queue custom-patterns republish --custom-pattern-id=?. Outdated alerts caused by edits during custom pattern backfills have been fixed in version 3.13 and above.

For instances deployed on Amazon Web Services (AWS), site administrators can configure regional AWS STS endpoints for OIDC from the Management Console.

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "Résolution des problèmes d’accès à la console de gestion."

The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn't required, and outputs an error instead of a warning.

On an instance hosted in AWS, system time may lose synchronization with Amazon's servers after an administrator reboots the instance.

On an instance with the HTTP X-Forwarded-For header configured for use behind a load balancer, all client IP addresses in the instance's audit log erroneously appear as 127.0.0.1.

When restoring from a backup snapshot, a large number of mapper_parsing_exception errors may be displayed.

Services may respond with a 503 status due to an out of date haproxy configuration. This can usually be resolved with a ghe-config-apply run.

Users can view the app state of gists, networks, and wikis in the spokesctl info output, enhancing visibility into the status of these elements. Additionally, spokesctl check can diagnose and, in most cases, fix empty repository networks, improving network management.

CRITICAL: On GitHub Enterprise Server instances that use SAML single sign-on (SSO) authentication with specific IdPs utilizing publicly exposed signed federation metadata XML, an attacker could forge a SAML response to provision and/or gain access to a user account with site administrator privileges. GitHub has requested CVE ID CVE-2024-6800 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could update the title, assignees, and labels of any issue inside a public repository. This was only exploitable inside a public repository, and private/internal repositories were not affected. GitHub has requested CVE ID CVE-2024-7711 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could disclose the issue contents from a private repository using a GitHub App with only contents: read and pull requests: write permissions. This was only exploitable via user access token, and installation access tokens were not impacted. GitHub has requested CVE ID CVE-2024-6337 for this vulnerability, which was reported via the GitHub Bug Bounty program.

Packages have been updated to the latest security versions.

During hotpatching and sometimes when applying configuration changes, a configuration run to upgrade the GitHub Actions service was unnecessarily triggered. The GitHub Actions service will only be upgraded in GitHub Enterprise Server feature releases.

On an instance with GitHub Actions enabled, during a hotpatch upgrade, a race condition could block various upgrade activities.

The ghe-config-apply process made an unnecessary number of connections to Redis.

Restarting the resolvconf service would not correctly update the contents of /etc/resolv.conf.

Instances installed on Google Cloud Platform (GCP) could have their hostname overwritten by GCP when a hotpatch was applied.

The minimum password requirements for Management Console users and the root site administrator required an upper case character when providing a password with a minimum of 8 characters, contradicting the documentation and password hint.

The ghe-migrations utility for visualizing migrations did not work due to a regression. Administrators can now run ghe-migrations to view the progress and status of github migrations, or run ghe-migrations --all to view progress on all services.

On an instance with subdomain isolation enabled, configuration runs created subdomains for ChatOps services, such as slack.HOSTNAME and teams.HOSTNAME, regardless of whether the service was enabled.

On an instance with GitHub Actions enabled, due to an insufficient wait time, MS SQL and MySQL replication could fail with the error message Failed to start nomad service!.

Site administrators could not switch maintenance mode directly from "scheduled" to "on," or vice versa.

Some users were unable to delete project views.

When importing using ghe-migrator, team URLs containing dots were imported as-is, leading to 404s when attempting to view the imported teams. Dots in imported team URLs are now escaped to dashes.

Due to a regression introduced in a previous patch, for enterprises that use encrypted SAML assertions, SSO attempts failed with a digest mismatch error if the entire SAML response was signed, rather than just the assertions.

Running go get for a Golang repository with a directory structure that overlaps with GitHub UI routes failed

The github-stream-processor service could get into a state where it would continually fail to process messages with a TRILOGY_CLOSED_CONNECTION error.

The wrong help link was displayed when push protection blocked a secret from the CLI.

For repositories with issues disabled, issue links were redirected to pull requests.

In custom pre-receive hooks, the paths stored in environment variables that allow for newly pushed objects to be in a quarantine directory could be incorrectly interpreted as relative to a worktree instead of the Git directory, causing certain commands to fail to read from the repository. The variables now use absolute paths.

A corrupted entry in the Git audit log could cause out of memory errors.

Fixes and improvements for the git core module.

Actions KPI logs are disabled by default to reduce log size.

Users can set their styling preference for link underlines in the web interface, on their "Accessibility" settings page.

Audit log events related to audit log streaming are available in the enterprise audit log page, and via audit log streaming.

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "Résolution des problèmes d’accès à la console de gestion."

If an instance is configured to forward logs to a target server with TLS enabled, certificate authority (CA) bundles that a site administrator uploads using ghe-ssl-ca-certificate-install are not respected, and connections to the server fail.

The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn't required, and outputs an error instead of a warning.

On an instance hosted in AWS, system time may lose synchronization with Amazon's servers after an administrator reboots the instance.

On an instance with the HTTP X-Forwarded-For header configured for use behind a load balancer, all client IP addresses in the instance's audit log erroneously appear as 127.0.0.1.

In GitHub Enterprise Server 3.10 and later, the requirements for TLS security levels have changed due to an upgrade to containers in the underlying OS. On an instance with GitHub Actions enabled and a custom TLS certificate, users may experience disruptions with workflow runs if the TLS certificate uses weak encryption. Workflow runs will not trigger, and the following error message will appear in system logs for babeld.

CA certificate key too weak

To resolve this issue, confirm that your certificate complies with level 2 of the OpenSSL security specification. For more information, see SSL_CTX_set_security_level in the OpenSSL docs. For more information about reviewing your instance's logs, see "À propos des journaux système."

If the error appears in babeld logs because your TLS certificate does not comply with level 2 of the specification, you must create and upload a new certificate with stronger security before you upgrade to GitHub Enterprise Server 3.10 or later. For more information, see "Configuration de TLS."

In some situations, large .adoc files stored in a repository do not render properly in the web UI. The raw contents are still available to view as plaintext.

After failing over an instance in a cluster configuration, Git pushes to the instance will fail. This issue impacts pushes from the command line as well as the web interface. To resolve this issue, contact GitHub Support.

On an instance in a cluster configuration, restoration of a backup using ghe-restore will exit prematurely if Redis has not restarted properly.

The HAProxy version has been updated in this release. You may encounter elevated error rates when HAProxy is upgraded as part of a hotpatch upgrade to a GitHub Enterprise Server instance. These elevated error rates should resolve within 5 minutes of the hotpatch being applied.

Please note, when performing a hotpatch upgrade to GitHub Enterprise Server version 3.11.1 or higher you will encounter this known issue only if you are hotpatching from GitHub Enterprise Server version 3.11.0.

Repositories originally imported using ghe-migrator will not correctly track Advanced Security contributions.

Due to a known regression, operators will not be able to use the ghe-migrations visualizer to view the status of migrations during an upgrade. Instead, the operator can inspect the log files in /var/log/dbmigration to see the status and progress of migrations.

The reply.HOSTNAME subdomain is falsely displayed as having no SSL and DNS record, when testing the domain settings via the Management Console without subdomain isolation.

Admin stats REST API endpoints may timeout on appliances with many users or repositories. Retrying the request until data is returned is advised.

If a hotpatch upgrade requires the haproxy-frontend service to be restarted, the restart will hang if there are existing long-lived connections, such as browser web sockets or Git operations. No new connections will be accepted for up to 5 minutes. Any existing unfinished connections at this time will be disconnected.

When restoring from a backup snapshot, a large number of mapper_parsing_exception errors may be displayed.

Services may respond with a 503 status due to an out of date haproxy configuration. This can usually be resolved with a ghe-config-apply run.

On boot, the resolvconf service may fail to start because the /run/resolvconf directory does not exist when the service attempts to touch a file there, with the error:

/bin/touch: cannot touch '/run/resolvconf/postponed-update': No such file or directory

If this occurs, workaround this issue with the following commands — this change will persist on reboots, but not upgrades:

sudo sed -i.bak \
'/\[Service\]/a ExecStartPre\=\/bin\/mkdir \-p \/run\/resolvconf' \
/etc/systemd/system/resolvconf.service.d/local.conf

sudo systemctl daemon-reload
sudo systemctl start resolvconf 

[Updated: 2024-08-26]

These release notes previously indicated as a known issue that on GitHub Enterprise Server 3.11.14 when log forwarding is enabled, some forwarded log entries may be duplicated. The fix for this problem was already included in GitHub Enterprise Server 3.11.13. [Updated: 2024-09-16]

HIGH: An attacker could cause unbounded resource exhaustion on the instance by sending a large payload to the Git server. To mitigate this issue, GitHub has limited the count of "have" and "want" lines for Git read operations. GitHub has requested CVE ID CVE-2024-5795 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An improper privilege management vulnerability allowed users to migrate private repositories without having appropriate scopes defined on the related personal access token. GitHub has requested CVE ID CVE-2024-5566 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could have unauthorized access in a public repository using a suspended GitHub App via a scoped user access token. This was only exploitable in public repositories while private repositories were not impacted. GitHub has requested CVE ID CVE-2024-5816 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could execute a Cross Site Request Forgery (CSRF) attack to perform write operations on a victim-owned repository in GitHub Enterprise Server by exploiting incorrect request types. A mitigating factor is that the attacker has to be a trusted user and the victim has to visit a tag in the attacker's fork of their own repository. GitHub has requested CVE ID CVE-2024-5815 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could disclose the name of a private repository on the GitHub Enterprise Server appliance when the private repository has a deploy key associated to it. GitHub has requested CVE ID CVE-2024-6395 for this vulnerability, which was reported via the GitHub Bug Bounty program.

LOW: Instance administrators could see fine-grained personal access tokens in plaintext in the babeld and gitauth logs.

LOW: An attacker with read access to a project could use the REST API to view a list of all members in an organization, including members who had made their membership private. This vulnerability was reported via the GitHub Bug Bounty program.

LOW: An attacker could include MathJax syntax in Markdown to bypass GitHubs normal restrictions on CSS properties in Markdown. This vulnerability was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could disclose sensitive information from a private repository exploiting organization ruleset features. This attack required an organization member to explicitly change the visibility of a dependent repository from private to public. GitHub has requested CVE ID CVE-2024-6336 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could have unauthorized read access to issue content inside an internal repository via GitHub projects. This attack required attacker access to the corresponding project board. GitHub has requested CVE ID CVE-2024-5817 for this vulnerability, which was reported via the GitHub Bug Bounty program.

Packages have been updated to the latest security versions.

When an instance hosted on Azure was upgraded with a hotpatch, the upgrade failed with an rsync error.

On an instance with GitHub Actions enabled, remote blob storage could fill up with large amounts of data because cleanup jobs were skipped on old hosts.

The threshold set by server_rejoin_age_max for single-node GHES deployments was too low.

In some cases, commands run in an administrative SSH shell were not written to the audit log.

When an administrator submitted support data to GitHub Support, spokesd keys were incorrectly sanitized.

When log forwarding was enabled, some specific service logs, including babeld, gitauth, unicorn, and resqued, were duplicated.

During the initial boot of an instance, a data disk attached as /dev/sdb may not have been recognized as an available disk.

In a high availablity configuration, running ghe-repl-node multiple times from a node that did not have replication running had the potential to overwrite the configuration on the primary node.

Configuration history is only generated for instances in a cluster, high availability (HA) cluster, or standalone HA configuration. The current node must be a primary or replica node with replication running.

In some cases, the HAProxy kill_timeout setting caused service outages during upgrades or large transactions.

The ssh-audit-log.sh script did not effectively log SSH commands, and the ghe-sanitize-log.psed script inadequately sanitized password-related logs.

The default MSSQL timeout of 8 seconds sometimes caused issues during administrator activities. The default timeout has been increased to 30 seconds.

For an instance running on Microsoft Azure, the user disk service failed to start because the attached volume could not be found.

Establishing a new GitHub Connect connection could fail with a 500 error.

When using ghe-migrator to migrate a repository, the links for pull requests merge commits were not imported.

When a user used the REST API endpoints that returned secret scanning alerts at the repository or organization level with non-cursor-based pagination (for example, without before or after query parameters), the REST API endpoints for secret scanning returned incorrect Link headers.

On certain branch names, the branch info bar was causing frozen string errors.

On instances with SAML authentication configured, users were unable to sign out and became stuck in an infinite SAML SSO loop.

On instances with SCIM enabled, the administrator was unable to view users without an external identity record (for example, because they were provisioned before SCIM was enabled on the instance) in stafftools.

On instances enrolled in the SCIM private beta, built-in authentication users can be added to organizations and teams. Organization owners will no longer see the misleading message that the organization membership is managed by the SAML identity provider when updating organization memberships.

Enterprise owners managed by an identity provider were asked to authenticate within GitHub when performing privileged actions.

On an instance that restricts emails to verified domains, secret scanning emails would sometimes be sent to an unverified domain.

In some cases, on the "Files" tab of a pull request, a comment on the first line did not render.

Some organizations were not recognized as part of an instance's enterprise account.

Some users would encounter an error when navigating to their personal security settings page at https://HOSTNAME/settings/security.

The SpokesSyncCacheReplicaJob could not initialize in some cases, resulting in an exception when handling the error.

On the "Code scanning" page of a repository, the branch filter did not correctly display all branches.

When including a .gitignore or README.md file on repository creation failed due to a ruleset or pre-receive hook, no error message displayed.

On an instance with a GitHub Advanced Security license, requests to the /enterprises/{enterprise}/settings/billing/advanced-security REST API endpoint could fail due to timeout.

Users viewing the alerts index page experienced inconsistencies in rendering the closed alert state.

Organizations named "C" were incorrectly routed to the GitHub Enterprise Server contact page instead of their organization page.

On an instance with a GitHub Advanced Security license, commits made by users who do not belong to an organization were not counted.

When servers responded with unsupported characters, webhook deliveries were not displayed in the UI.

Chat integrations required frequent reauthentication, as a result of new app installations overwriting previous ones.

On an instance in a cluster configuration, the ghe-spokesctl ssh command did not select the correct Nomad container when running a command within a Git repository.

On an instance with a GitHub Advanced Security license, disabling and re-enabling GitHub Advanced Security for an organization resulted in redundant scans of some repositories.

On an instance with a GitHub Advanced Security license, contributions were not tracked on public repositories.

On an instance with a GitHub Advanced Security license, the "adjust configuration" step failed when enabling code scanning with the default setup on self-hosted Windows runners.

Migration of the issue_edits table caused intermittent failures during the upgrade to GitHub Enterprise Server version 3.11, resulting in the error message ActiveRecord::ConcurrentMigrationError: Failed to release advisory lock. [Updated: 2024-08-14]

In a high availability configuration, users can only run ghe-config-apply or ghe-cluster-config-apply on a replica node if replication is already running (from ghe-repl-start). If replication isnt running on the node, the user will be instructed to start replication.

Configuration history has been extended. When ghe-config-apply, ghe-cluster-config-apply, or ghe-config-archive is run: secrets.conf is captured, a sha256sum for each of the current configuration files is included, the existing patch that is generated includes secrets.conf, and an additional sanitized patch that excludes secrets.conf is also generated.

The timeout for requests made to the REST API endpoints for secret scanning has been extended.

A more specific error message is shown when a non-provisioned user tried to sign in to an instance with SCIM enabled.

In some environments, stale .backup log files could accumulate in the system.

On an instance hosted on AWS, when configuring GitHub Packages, virtual-hosted-style AWS S3 URLs would default to path-style URLs if a region-code was included. For more information, see Virtual hosting of buckets in the AWS documentation.

In some cases, when an administrator uploaded a custom TLS certificate, the certificate was not correctly installed on the instance.

Because the | character was not permitted, administrators could not add an SMTP username to authenticate with the Azure Communication Service.

In some cases, upgrades to GitHub Enterprise Server 3.11 could fail due to the Consul server failing to start.

Endpoints for the REST API's Manage GitHub Enterprise Server operation returned internal service error if cluster.conf was not found on the instance.

On an instance with GitHub Actions enabled, an issue with GH_TOKEN sometimes prevented GitHub Pages sites from building successfully in workflows.

An administrator could enable GitHub Connect on an instance with a license that does not support GitHub Connect.

On an instance with GitHub Connect enabled, some system users were incorrectly counted as consuming a license following license sync.

A user in the process of being converted into an organization could be added as a collaborator on a repository. This resulted in the new organizations owners unexpectedly receiving access to the repository.

When using ghe-migrator to import repositories into GitHub Enterprise Server, the conflicts and audit subcommands produced an invalid CSV file due to an extra log line appended to the file.

On an instance with a GitHub Advanced Security license and secret scanning enabled, dry runs sometimes incorrectly reported no results for custom patterns.

On an instance with a GitHub Advanced Security license and secret scanning enabled, webhooks for alert locations did not contain information about push protection bypasses.

On an instance with Dependabot updates enabled, Dependabot relies on the node installation provided by the actions runner instead of dynamically downloading.

To avoid negative effects on disk utilization, babeld log files have a maximum size of 15 GB.

When using ghe-migrator prepare to import an archive, a missing schema.json file results in an UnsupportedArchive error rather than an UnsupportedSchemaVersion error.

The audit log now tracks all failed password attempts individually. Previously, duplicate failed password attempts in sequence within the same day would be grouped into one failed password attempt, with a count field.

On an instance in a cluster configuration, administrators can identify the repository networks or gists that are common across a specified set of storage nodes using the spokesctl find-on-replicas command.

Hotpatch upgrades from GitHub Enterprise Server version 3.11.0 to 3.11.1 will result in the appliance losing network connectivity after a reboot. If you have upgraded to GitHub Enterprise Server 3.11.1 from 3.11.0 using a hotpatch upgrade, please contact GitHub Support for assistance. If you have upgraded directly to GitHub Enterprise Server 3.11.1 from previous versions (for example, from any version of GitHub Enterprise Server in the 3.9 or 3.10 series), your instance is not affected by this issue. [Updated 2023-12-27]

Custom firewall rules are removed during the upgrade process.

The GitHub Packages npm registry no longer returns a time value in metadata responses. This was done to allow for substantial performance improvements. We continue to have all the data necessary to return a time value as part of the metadata response and will resume returning this value in the future once we have solved the existing performance issues.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "Résolution des problèmes d’accès à la console de gestion."

If an instance is configured to forward logs to a target server with TLS enabled, certificate authority (CA) bundles that a site administrator uploads using ghe-ssl-ca-certificate-install are not respected, and connections to the server fail.

The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn't required, and outputs an error instead of a warning.

On an instance hosted in AWS, system time may lose synchronization with Amazon's servers after an administrator reboots the instance.

On an instance with the HTTP X-Forwarded-For header configured for use behind a load balancer, all client IP addresses in the instance's audit log erroneously appear as 127.0.0.1.

In GitHub Enterprise Server 3.10 and later, the requirements for TLS security levels have changed due to an upgrade to containers in the underlying OS. On an instance with GitHub Actions enabled and a custom TLS certificate, users may experience disruptions with workflow runs if the TLS certificate uses weak encryption. Workflow runs will not trigger, and the following error message will appear in system logs for babeld.

CA certificate key too weak

To resolve this issue, confirm that your certificate complies with level 2 of the OpenSSL security specification. For more information, see SSL_CTX_set_security_level in the OpenSSL docs. For more information about reviewing your instance's logs, see "À propos des journaux système."

If the error appears in babeld logs because your TLS certificate does not comply with level 2 of the specification, you must create and upload a new certificate with stronger security before you upgrade to GitHub Enterprise Server 3.10 or later. For more information, see "Configuration de TLS."

In some situations, large .adoc files stored in a repository do not render properly in the web UI. The raw contents are still available to view as plaintext.

After failing over an instance in a cluster configuration, Git pushes to the instance will fail. This issue impacts pushes from the command line as well as the web interface. To resolve this issue, contact GitHub Support.

Restoring backups with ghe-restore on a GHES cluster will exit prematurely if redis has not restarted properly.

The HAProxy version has been updated in this release. You may encounter elevated error rates when HAProxy is upgraded as part of a hotpatch upgrade to a GitHub Enterprise Server instance. These elevated error rates should resolve within 5 minutes of the hotpatch being applied.

Please note, when performing a hotpatch upgrade to GitHub Enterprise Server version 3.11.1 or higher you will encounter this known issue only if you are hotpatching from GitHub Enterprise Server version 3.11.0. [Updated 2024-01-03]

During periods of high traffic, interruptions in service may occur due to insufficient resource allocations for internal components. [Updated 2024-01-23]

The settings for enabling scheduled reminders were added unintentionally to this release. Scheduled reminders are not officially supported. [Updated: 2024-02-22]

Redundant messages may cause an increase in the volume of events logged in /var/log/syslog. [Updated: 2024-03-08]

If a hotpatch upgrade requires the haproxy-frontend service to be restarted, the restart will hang if there are existing long-lived connections, such as browser web sockets or Git operations. No new connections will be accepted for up to 5 minutes. Any existing unfinished connections at this time will be disconnected. [Updated: 2024-06-17]

Interactive maps in the web UI no longer allow authentication using an Azure Maps API key

• To allow users to render interactive maps in an instance's web UI by writing GeoJSON or TopoJSON syntax, GitHub Enterprise Server previously required a potentially unsecure API key for authentication with Azure Maps. If an administrator previously enabled interactive maps on an instance, the feature is disabled upon upgrade to this release.

  To re-enable interactive maps for your instance, you must configure an application on an Entra ID tenant that has access to Azure Maps using role-based access control (RBAC). For more information, see "Configuration des cartes interactives" and the security fixes for this release.

Instance administration

• Instance administrators can perform administrative tasks using the gh es extension for the GitHub CLI. The extension communicates with your instance's management API, so you don't need to SSH into the instance or write a custom application. For more information, see "Administration de votre instance à l’aide de l’interface CLI GitHub."

Authentication

• To help users discover the required permissions for calls to a REST API endpoint, GitHub Enterprise Server returns the X-Accepted-GitHub-Permissions header for requests to endpoints that use fine-grained permissions, including requests from GitHub Apps. For more information, see the following articles.

  • "Résolution des problèmes de l’API REST"
  • "Autorisations nécessaires pour les jetons d’accès personnels affinés"
  • "Autorisations requises pour les applications GitHub"

Audit logs

• The web interface for enterprise, organization, and user audit logs include an expandable view that displays the full audit log payload for each event. Administrators and users can see the same event metadata when searching the audit log in the web interface or via streaming. For more information, see the following articles.

  • "À propos du journal d’audit de votre entreprise"
  • "Examen du journal d’audit de votre organisation"
  • "Examen de votre journal de sécurité"

GitHub Advanced Security

• On an instance with GitHub Actions enabled, in repositories that use default setup for code scanning, the default setup configuration updates automatically if GitHub detects new languages. Users can view a repository's language configuration for default setup from the repository's "Code security and analysis" settings page. Additionally, users can view information about setup and debug failed languages from the tools status page. For more information, see the following articles.

  • "Définition de la configuration par défaut pour l’analyse du code à grande échelle"
  • "Définition de la configuration par défaut pour l’analyse du code"
  • "À propos de la page d’état de l’outil pour l’analyse du code"

• On an instance with GitHub Actions enabled, default setup for code scanning at the organization level is now generally available. For more information, see "Définition de la configuration par défaut pour l’analyse du code à grande échelle" and "Points de terminaison d’API REST pour les organisations" in the REST API documentation.

• On an instance with GitHub Actions enabled, during configuration of default setup for code scanning, users can select either the "Extended" or "Default" query suite for eligible repositories in an organization. For more information, see "Suites de requêtes CodeQL" and "Définition de la configuration par défaut pour l’analyse du code."

• On an instance with GitHub Actions enabled, to better protect active and inactive repositories, GitHub Enterprise Server automatically analyzes repositories that use a default setup for code scanning. The analysis runs on a weekly schedule and uses the most recent version of CodeQL. When configuring code scanning, the fixed time for the weekly scan is randomly chosen. The scan will take place at the same time every week, and the schedule is displayed after the setup is completed, so users can easily see when the next scheduled analysis will occur. The scheduled analysis will be automatically disabled if a repository has no activity for six months. Creation of a pull request or pushes to the repository will re-enable scheduled analysis.

• Code scanning default setup is available for Swift analysis with CodeQL. For more information, see "Définition de la configuration par défaut pour l’analyse du code."

• CodeQL 2.14.6 and later supports analysis of code written in Go 1.21. For more information, see "Supported languages and frameworks" in the CodeQL documentation.

• With CodeQL model packs for Java, users can improve code scanning results by ensuring that any custom Java libraries and frameworks used by their codebase are recognized by CodeQL. For more information, see the following documentation.

  • "Modification de la configuration d’installation par défaut"
  • "Personnalisation de votre configuration avancée pour l’analyse de code"
  • "Using the CodeQL model editor" in the CodeQL documentation

• For instances with GitHub Connect configured, code scanning with CodeQL supports Java codebases that use Project Lombok. Previously, code scanning users were able to scan Java applications that contained Lombok code, but all the contents of files containing Lombok code were either skipped or users had to apply a workaround to prepare the applications for scanning. Lombok features will now be automatically scanned without requiring any workaround.

  For more information about syncing the required GitHub Actions workflow to scan Lombok code, see "Configuration de l’analyse de code pour votre appliance."

• Push protection for secret scanning is now generally available. For more information, see "À propos de la protection push."

• To prevent the leak of tokens where users work outside of code, secret scanning detects tokens in both new and historical issue titles, descriptions, and comments. When a new token type is added to secret scanning, GitHub Enterprise Server scans for matches automatically. This expanded coverage also detects and surfaces secrets that match any custom pattern defined at the repository, organization, or enterprise level. These secrets appear both in the web interface and in queries to the REST API. For more information, see "À propos de l’analyse des secrets" and "Définition de modèles personnalisés pour l’analyse des secrets."

• Users can view metrics associated with push protection usage across an organization. The overview shows a summary of blocks and bypasses, as well as more granular metrics. For more information, see "Évaluation des risques liés à la sécurité de votre code."

• A new REST API endpoint is available for dataflow analysis using custom CodeQL queries. The new endpoint offers additional flexibility, includes improvements that prevent common pitfalls with the old API, and improves the performance of query evaluation by five percent. For more information, see New dataflow API for writing custom CodeQL queries in the GitHub Changelog.

Dependabot

• For developers who manage Node.js dependencies using the pnpm package manager, pnpm is fully supported by dependency graph, Dependabot alerts, and Dependabot security updates. For more information about securing your supply chain with Dependabot, see "Sécuriser votre chaîne d’approvisionnement avec Dependabot."

• Developers can enforce policies related to vulnerabilities and licenses in pull requests for complex ecosystems with transitive dependencies like Gradle and Scala. Dependency review supports dependencies from the dependency submission API. For more information, see the following articles.

  • "À propos de la vérification des dépendances"
  • "À propos de la vérification des dépendances"
  • "Utilisation de l’API de soumission de dépendances"

• To control how Dependabot structures pull requests and improve mergeability, users can implement flexible grouping options in dependabot.yml. You can also control Dependabot's behavior for groups using comment commands. For more information, see "Options de configuration pour le fichier dependabot.yml" and "Gestion des demandes de tirage (pull request) pour les mises à jour des dépendances."

• Dependabot can open pull requests for Swift and Gradle dependencies.

  • Users can also configure scheduled updates for Swift dependencies using dependabot.yml.
  • If users have used the REST API for dependency submission to upload Gradle dependencies to the dependency graph and receive Dependabot alerts for those dependencies, Dependabot will try to open a pull request to resolve security updates enabled for the repository.

  For more information, see "Configuration des mises à jour de sécurité Dependabot."

• Responses from REST API endpoints for repositories display whether Dependabot security updates are enabled or disabled. Users can also enable or disable security updates for a repository using the REST API. For more information, see "Points de terminaison d’API REST pour les référentiels" in the REST API documentation.

• When Dependabot is first enabled, GitHub will not send notifications for all vulnerable dependencies found in the repository, only for new vulnerable dependencies ifentified after Dependabot is enabled. For more information, see "Configuration de notifications pour les alertes Dependabot."

Code security

• To assess risks to code security and ensure adoption of features to improve code security, the "Security risk" and "Security coverage" pages for organizations and the entire instance are generally available. Additionally, the alert-centric pages for Dependabot, code scanning, and secret scanning are also now generally available. For more information, see "Assessing your code security risk" and "Assessing adoption of code security features."

• Users can take advantage of the GitHub Advisory Database using the REST API. The Advisory Database is a free, open-source list of actionable security advisories and CVEs. API responses include machine-readable mappings to the ecosystem, package name, and affected versions of impacted software. For more information, see "Points de terminaison d’API REST pour les avis de sécurité globaux" in the REST API documentation.

GitHub Actions

• For self-hosted GitHub Actions runners on this GitHub Enterprise Server release, the minimum required version of the GitHub Actions Runner application is 2.309.0. See the release notes for this version in the actions/runner repository. If your instance uses ephemeral self-hosted runners and you've disabled automatic updates, you must upgrade your runners to this version of the Runner application before upgrading your instance to this GitHub Enterprise Server release. [Updated: 2024-04-25]

• To better navigate, trace, understand, and monitor deployments, users can view and track the full history of deployments in a repository or filter across environments. For more information, see "Consultation de l’historique de déploiement."

• Users can improve the security of deployment environments by configuring a branch protection policy to only allow specific branches to deploy to an environment. Additionally, the following security improvements apply to environments.

  • GitHub Enterprise Server blocks runs triggered from forks with branch names that match the protected branch's name.
  • Tags with the same name as a protected branch cannot deploy to the environments with a branch protection configuration.

  For more information, see "Gestion des environnements pour le déploiement."

• On an instance with GitHub Actions enabled and a configuration for deployment environments, administrators for environments can improve the security of deployments by enforcing a review by someone other than the person who triggered the run. This option prevents required reviewers from self-reviewing to trigger workflows. For more information, see "Gestion des environnements pour le déploiement."

Organizations

• Organization owners can signal that an organization is no longer actively maintained by archiving the organization. For more information, see "Archivage d’une organisation."

Repositories

• Users can govern protections for branches and tags in a repository using repository rules. To govern the protections for all of an organization's repositories, users can also enable rulesets for an organization. Contributors to a repository can see which rules apply via the web interface, Git, or the GitHub CLI. For more information, see "À propos des ensembles de règles."

• Users can create new repositories with predefined attributes using query parameters. For example, a user can create a URL that prepopulates information about the repository like the name, description, visibility, and more. For more information, see "Création d’un dépôt."

• Users can more easily understand changes to a repository using the activity view. For more information, see "Utilisation de l’affichage d’activité pour afficher les modifications apportées à un référentiel."

Issues

• Users can automatically add a new issue to projects using a custom issue form by defining projects in the issue template. For more information, see "Syntaxe des formulaires de problème."

Projects

• Users can review items in a project view broken down by a certain field value. For more information, see "Personnalisation de la disposition de tableau."

• Users can create charts to visualize current project items, or visualize project items over time. For more information, see "À propos des insights des Projects."

Accessibility

• To improve the visibility of links with blocks of text in the web interface for GitHub Enterprise Server, users can apply underline styling. For more information, see "Gestion des paramètres d’accessibilité."

The speed of restoration operations with GitHub Enterprise Server Backup Utilities has increased.

Configuration runs now correspond with a unique ID. During the run, the log remains at /data/user/common/ghe-config.log. After the run, the instance rotates the log's contents into /data/user/config-apply/logs/YYYYMMDD/ghe-config.HOSTNAME.ID.log, where YYYYMMDD is the date of the run, HOSTNAME is the hostname of the node, and ID is the ID of the run. For more information, see "À propos des journaux système."

Field names for some service logs on GitHub Enterprise Server have changed as part of GitHub's gradual migration to internal semantic conventions for OpenTelemetry. Additional field names were changed in GitHub Enterprise Server 3.9 and 3.10. If any tooling or processes in your environment rely on specific field names within logs, or log entries in specific files, the following changes may affect you.

• level is now SeverityText.
• log_message, msg, or message is now Body.
• now is now Timestamp.
• Custom field names such as gh.repo.id or graphql.operation.name use semantic names.
• Log statements that the instance would previously write to auth.log, ldap.log, or ldap-sync.log now appear in containerized logs for github-unicorn if the statement originated from a web request, or in logs for github-resqued if the statement originated from a background job. For more information about containerized logs, see "À propos des journaux système."

For a full list of mappings, download the OpenTelemetry attribute mapping CSV for GitHub Enterprise Server 3.9, 3.10, and 3.11.

On an instance that uses built-in authentication or LDAP, if two-factor authentication (2FA) is configured for an organization, a user could use a TOTP code multiple times within the code's window of validity during authentication or when entering sudo mode for sensitive actions. To improve security, this reuse is no longer allowed. External systems with a scripted login flow across multiple parallel jobs may stop working as a result of this change.

For more information about 2FA, see the following articles.

• "Exiger l’authentification à 2 facteurs pour une organisation"
• "Mode sudo"
• "Configuration de l’authentification à 2 facteurs"

On an instance with a GitHub Advanced Security license, during analysis of Python projects with code scanning using CodeQL and an advanced setup, GitHub Enterprise Server would automatically install dependencies for the project. Due to improvements to CodeQL, GitHub Enterprise Server no longer needs to fetch these dependencies to analyze a codebase. To improve scan times for Python projects, automatic dependency installation is disabled.

If you configured code scanning with CodeQL via advanced setup to disable dependency installation, GitHub recommends setting setup-python-dependencies to false for the configuration. For more information, see "Personnalisation de votre configuration avancée pour l’analyse de code."

On an instance with Dependabot enabled, due to misconfiguration or incompatible versions, Dependabot jobs for a repository can fail. After 30 failed runs, subsequent scheduled jobs will fail immediately until you trigger a check for updates from the dependency graph, or until you update a manifest file. Jobs for Dependabot security updates will still trigger normally.

On an instance with GitHub Advanced Security, to help users more efficiently review and filter code scanning alerts at scale using the REST API, the updated_at field in API responses is improved. The updated_at timestamp now represents an alert's most recent state change on the branch that you requested. State changes include an alert being introduced, fixed, dismissed, reopened, or reintroduced. Previously, the updated_at timestamp changed frequently, whenever an alert was found in an analysis or the alert state changed. For more information about using the REST API to retrieve code scanning alerts, see "Points de terminaison d’API REST pour l’analyse de codes" in the REST API documentation.

On an instance with Dependabot enabled, the following improvements apply to the repository view for dependency graph, available from the repository's "Insights" tab.

• Users can search by package name from a paginated list of all dependencies.
• Dependency licenses are displayed.
• Dependabot alerts appear for dependencies, sorted by severity, and link to the Dependabot alerts and the Dependabot update pull request where applicable.

For more information about the dependency graph, see "À propos du graphe de dépendances."

After first enabling Dependabot on an instance, GitHub Enterprise Server will no longer send web or email notifications for repositories that are initially populated with Dependabot alerts. This allows you to review the new Dependabot alerts for a repository, organization, or the entire instance without immediately notifying other users of existing alerts.

On an instance with GitHub Actions enabled, workflows that use Node.js 16 or earlier will log a warning. Node.js 16 has been end-of-life since September 2023.

• Workflow authors should update actions to run on Node.js 20. For more information, see "Metadata syntax for GitHub Actions."
• Users with workflows that use Node.js should specify Node.js 20 or later in the workflows using versioned actions. For more information, see "Workflow syntax for GitHub Actions."

[Updated: 2024-03-05]

On an instance with GitHub Actions enabled and runners using GitHub Actions Runner 2.309.0 or later, users can no longer use GITHUB_ENV to set the NODE_OPTIONS environment variable in workflows. Workflows that set NODE_OPTIONS as an environment variable will now log the following error. For more information, see "Workflow commands for GitHub Actions" and the v2.309.0 release in the actions/runner repository on GitHub.com.

Can't store NODE_OPTIONS output parameter using '$GITHUB_ENV' command.

Users can quickly take action on multiple items in a group, or the group itself, using the ••• button in a table, board, or roadmap.

Users can break out items in a project by workstreams, team members, priorities, or other groupings using a swimlane view. For more information, see "Personnalisation de la disposition en panneau."

Users can view view the template used to create a project from a project's settings.

When scrolling through a project, group headers are now sticky.

The colors for single-select fields in a project have been updated, so users see the same colors within the field picker and within project views.

Users create can create issues in a project view that's grouped by repository in the board layout by clicking "Create new issue", or by starting to type the issue's title.

An upgrade to GitHub Enterprise Server 3.11.0 may fail, hanging on the "Reloading system services" screen. The following error will appear in /var/log/syslog.

agent: Error starting agent: error="Failed to start Consul server: Failed to start Raft: failed to load any existing snapshots"

This issue is resolved in GitHub Enterprise Server 3.11.1. When upgrading to a release in the 3.11 series, upgrade to 3.11.1 or later. [Updated 2023-12-21]

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time.

• The enterprise-level "Security overview" page is deprecated in favor of the new "Security risk" and "Security coverage" pages. For more information, see "Évaluation des risques liés à la sécurité de votre code" and "Évaluation de l'adoption des fonctionnalités de sécurité du code."

Dependabot updates no longer support Python 3.6 or 3.7

• Dependabot updates no longer support Python 3.6 or 3.7, which have reached end-of-life. If a user's code uses these versions, Dependabot will no longer be able to open pull requests in your repository and will log errors. Update to Python 3.8 or later to ensure your code is secure and Dependabot can still run.

  Users will continue to receive Dependabot alerts for dependencies with known vulnerabilities. To resolve these alerts, users can manually upgrade the affected package.

  For more information about Python releases, see Status of Python versions on the Python website. For more information about supported package managers for Dependabot, see "À propos des mises à jour de version Dependabot."

Upcoming deprecation of team discussions

• GitHub will deprecate team discussions for users in GitHub Enterprise Server 3.13. In GitHub Enterprise Server 3.11, a banner appears atop teams' discussions with information about the deprecation, including a link to tooling to migrate existing team discussions to GitHub Discussions. For more information, see "À propos des discussions d’équipe" and "À propos des discussions." [Updated: 2024-03-04]
