What changed
Agent checkpoints and the Restore Checkpoint action were removed in Zed 1.27.0. To undo agent changes you now reject the edits or use Git. The release also cut the agent panel’s memory and CPU use and stopped reading model credentials when AI is turned off.
Who it affects
Zed users who rely on the agent panel.
What to do
Commit before letting the agent make large changes, and use Git or reject edits to undo.
