After an update, a familiar editor can start saving agent changes through a different path. Devin Desktop’s latest stable notes include settings that affect what reaches your working files.
The Agent Window moves closer to Devin web
The Devin Desktop changelog dates version 3.11.212 to October 23. Its Agent Window adopts the web app interface, including session navigation, Review, settings, and other session tools.
The release lets you view up to eight sessions side by side. Local sessions also gain a Changes tab with file diffs and a view of changes since they were last seen. The relevant location matters: a terminal can belong to the session’s remote machine or a local folder.
These are editor and workflow changes. They do not establish a new SWE-2 model or a measured improvement in code quality.
Inspect the defaults that affect agent edits
With agent diff zones disabled by default in this release, changes from the agent reach files directly. Users can enable those zones again through the editor’s settings.
The same release says agent edits save without running format-on-save or code actions. A setting to run save actions on agent edits restores that behavior. If your workflow depends on a formatter or a save-time transformation, verify that setting after upgrading.
The editor also stops opening changed files in the background by default. Users who depend on that navigation can re-enable automatic opening. These choices affect how a developer notices and reviews work, even when the resulting code change is small.
Run a disposable-repository review
Use a copy or a small test repository before relying on the new behavior in a production project. Record the installed version and current settings first.
- Create a file with a harmless formatting difference.
- Ask the agent for a small change to that file.
- Inspect the actual file and its diff after the agent finishes.
- Check whether the expected formatter or code action ran.
- Enable the desired save-action behavior and repeat the same small edit.
- Review the complete diff before committing the trial result.
This proposed check separates a saved edit from the team’s usual finishing steps. If a formatter is also part of CI, the editor setting and CI may catch different stages of the same workflow. Neither replaces review of the code’s behavior.
October 24 adds focused fixes
Version 3.11.216 is dated October 24. Its notes include access to local sessions for members without cloud-session permissions, CLI setup fixes, and a fix for local-session crashes involving inline terminal images.
The October 23 release also documents changes to how Enter steers a running turn and how queued messages work. Teams should review those interaction details alongside the editing defaults when adapting their instructions.
