Troubleshooting issues caused by version incompatibility

Changes to GitHub Copilot Chat coincide with Visual Studio Code releases, due to Copilot Chat's deep UI integration. As a result, every new version of Copilot Chat is only compatible with the latest release of Visual Studio Code. This means that if you are using an older version of Visual Studio Code, you will not be able to use the latest Copilot Chat.

Only the latest Copilot Chat versions will use the latest large language model provided by the Copilot service, as even minor model upgrades require prompt changes and fixes in the extension. An older version of Copilot Chat will still use the latest version of Copilot code completions.

To use GitHub Copilot Chat, make sure you are using the latest version of Visual Studio Code.
