Recently shipped Memory, which carries what Devin learns across sessions, plus nightly "dreaming" that refines it.
Memory persists across sessions. Memory is personal to you, not shared with your organization, and can be reviewed or switched off under Settings > Customization > Memory. Each night Devin reviews recent sessions and refines what it remembers.
Sessions are easier to steer.
- Sessions now resume for 14 days after they sleep, down from 30 — history stays available, but new work from an older session needs a new session.
- A message that already has a side chat can start another, each reachable from a thread menu.
- Queued messages stay editable — send, edit, remove, reorder — after Devin stops or the session sleeps.
- Interrupting Devin keeps the partial reply in the chat.
- A sidebar notification inbox collects session updates; messages sent as a connection drops are saved server-side.
- Search mode, changed-files layout, and sidebar filters now sync across devices.
The workspace gained a Terminal and sharper reviews.
- The new Terminal tab runs commands on Devin's machine; opening Files or Terminal wakes a sleeping session.
- Code blocks and shell output render in Devin Mono, and the streaming terminal preview is now a read-only text view.
- Devin fixes merge conflicts on its own PRs more often — within 12 hours of session activity, 36 if the PR is approved.
- The PR tab gained a file tree and a Smart diffs toggle.
Attachments, models, and marketplace. Drop a folder on the composer to attach it whole; it is zipped in your browser. The capability picker now names its models: Ultra uses Fable 5.1 and GPT-6 Astra, Normal lists Fable 5.1, Opus 5 and GPT-6 Astra. The MCP marketplace added AWS and Braintrust servers.
