v0.226.0

v0.226.0 removes hosted chat publishing, a pre-release feature that was never used. It adds image thumbnails to the messages you send. It also fixes six problems: the Local model setup step and its connection test, memories that could fail to save while the database was busy, web searches that reported "no results" when they were rate-limited, chat export during a running turn, and a right panel that ran off narrow windows.

Added

• Image thumbnails in your chat messages. Images you attach now show as small thumbnails in your message. Click one to see a larger preview. Only the thumbnail is saved with the chat, not the full-size image. File attachments keep their filename labels. (#4700)

Removed

• Hosted chat publishing and its chat.publish developer flag. The hosted viewer it needed was never built, so the feature could not leave pre-release. Removed: the /publish command, the tab menu item, Settings ▸ Publish, the publish and published-links routes, and the publish.endpoint_url, publish.timeout_seconds and publish.revoke_endpoint_url config fields. /export is unchanged. (#4701)

Fixed

• The Local model setup step is shorter, and large local models have time to load. The step lists only the servers you can use, picks the model from a dropdown, and puts the endpoint under "Use a different address". The connection test runs on its own, and a failed test offers Try again. Testing a model running on this machine now waits up to two minutes instead of 20 seconds, so a large model that is still loading no longer fails with a timeout. Hosted endpoints keep the 20-second limit. (#4706)
• A memory could fail to save when the database was busy. With several writes running at once, saving a memory could fail with "database is locked" and the memory was lost. Memory writes now take the database lock first and retry briefly. (#4705)
• web_search no longer reports a rate-limited search as "no results". A throttled DuckDuckGo search is retried once after a short wait, on another backend when one is available. If both tries fail, the tool says the search failed or was rate-limited. "No results" now means a search that actually ran and found nothing. (#4690)
• A scheduled retry no longer ends the turn without saying why. When the agent schedules a retry after a tool fails, it is now told to say what went wrong and what will run next. Before, it could end the turn with a bare "I'll pick this back up". Scheduling itself is unchanged. (#4688)
• Chat export works during a running turn. Exporting a chat while a reply is still being generated no longer waits for the turn to finish. The export contains the chat as last saved, is marked as still in progress, and leaves out tool calls that have not been answered yet. (#4691)
• The right panel stays inside the window. A right panel saved wider than the current window now shrinks to fit. It goes back to its saved width when the window gets wider again. (#4693)

Upgrading

• Hosted chat publishing is gone: /publish, Settings ▸ Publish, its routes and the publish.* config fields. It was behind a developer flag that was off by default, and its hosted service never existed, so almost nobody is affected.
• If your config.yaml still has a publish: section, it is ignored, and it is kept when settings are saved. Any published_links.json file stays on disk.
• /export is unchanged. There is nothing else to change, and no restart is needed beyond the normal update.
