Diffs now show images as pictures, the repository panel speaks Gitea, and workspace backgrounds get a wallpaper market.
Desktop notifications become a real setting, and backup & restore stops losing custom-agent conversations.
New
- A wallpaper market for the workspace background — browse the public Wallhaven SFW gallery from Settings → Appearance, and one click downloads and applies a wallpaper. (#626, @user-A100)
- Image files now diff as before/after pictures, with a swipe slider, in the workspace diff tab, the commit dialog, the push workspace and the unstash dialog.
- The repository panel now works against Gitea and Forgejo, with a Gitea accounts section under Settings → Version Control.
- Desktop notifications are now configurable in Settings → General: a master switch, when to notify, whether to hide contents, and one switch per event.
- A deleted conversation can be restored from the session picker — turn on "Include deleted", and importing one brings the original conversation back with its history intact.
- The status bar reports the codeg-mcp service and lets you switch its tool groups — delegation, live feedback, ask-a-question, session lookup, automations and work tasks — right in the popover.
- Claude now marks where its context was compacted, live and after reopening, saying whether it was triggered manually or automatically (claude-agent-acp 0.75.1).
- Every restore is snapshotted first and can be rolled back, with real progress, a cancel button and a result panel.
Improved
- Updated bundled agents: CodeBuddy 2.146.0, Qoder 1.1.45, Gemini CLI 0.58.0, OpenClaw 2026.9.2, and the Claude adapter (claude-agent-acp 0.75.1).
- Settings → General now opens with the notification and sound sections folded, instead of filling the page before anything below them.
- Refreshed model catalogs — Codex gains gpt-6-astra, OpenCode grows to 213 providers and 7,562 models, and gpt-6 sessions finally show a context meter.
Fixed
- A backup no longer loses custom ACP agents' conversations — their message text was packed by neither the backup nor the restore path, so a round trip left every conversation in place and empty.
- OpenCode, Hermes, Cursor and Antigravity session databases now survive a backup round trip whole, instead of losing their newest messages and being restored beside a stale write-ahead log.
- Forking a Claude conversation from a branch an earlier fork left behind now lands on the reply you picked, instead of quietly falling back to the end of the conversation (claude-agent-acp 0.75.1).
- A failed task push-back now reports git's own reason, instead of always blaming the fork author for not allowing maintainer edits.
