 - Chat: Chat has been added back to the VS Code sidebar (after being removed about 6 months ago). By default, new chats open in the sidebar. New chats can still be opened in an editor panel with the `New Chat in Sidebar` command. Currently open chats can be moved from the sidebar into an editor panel and vice versa. Enterprise users are not affected. [pull/4832](https://github.com/sourcegraph/cody/pull/4832)
 - Chat: Chat History, commands, and settings are now accessible through the chat view for Non-Enterprise users. [pull/4900](https://github.com/sourcegraph/cody/pull/4900)
 - Edit: Added support to select the full range of a file for an edit. [pull/4864](https://github.com/sourcegraph/cody/pull/4864)
