Download codeg 0.40.0

This release redesigns how conversations show an agent’s work: a new activity timeline brings thoughts, commands, file changes and sub-agent tasks together, making progress easier to follow and results easier to review.
New
- A new activity timeline presents the agent’s work step by step, with a summary of the step count, elapsed time and failures.
- Tool permission decisions stay with the conversation, so “approved once”, “always allowed” and “declined” records remain available after you reopen it.
- File edits in conversations support inline and side-by-side comparison, with synchronized horizontal scrolling and a file header that opens the file in the workspace.
Improved
- Clicking the Activity header expands or collapses the steps, while clicking its failure indicator takes you straight to the failed step.
- Consecutive file lookups and commands are grouped automatically, with completed command groups folding away while unresolved failures stay open.
- Command rows explain what the command does when the agent provides a description, and their detail panels show the full command or script alongside its output, with separate copy actions.
- Sub-agent tasks show their task, completed steps, current work and latest result, and running tasks remain visible when you collapse the parent reply.
- Message navigation in Session Details uses a more compact layout for sub-agents and changed files, while messages, code blocks and detail panels blend more naturally with workspace background images.
- Long conversations and streaming replies feel smoother, with steps remaining clickable during scrolling and no more repeated jumping near the bottom.
Fixed
- Command results show exit codes more reliably, including codes recorded separately from the output by Pi, Cursor and Antigravity.
- Codex’s context-compaction indicator appears while compaction is running, instead of only after it finishes.
- Expanded thoughts preserve their line breaks and list formatting, and English text, code and diffs display correctly in the Arabic interface.
Note
- Back up codeg’s data folder before updating if you may need to return to 0.39.0, because 0.40.0 updates the database and 0.39.0 cannot start on that updated data, including through codeg-server’s Roll back or reinstalling the older desktop app.
