v0.7.2
Another patch primarily cleaning up support for Opus 4.5:
Model improvements:
- Opus 4.5 uses Anthropic's new effort parameter instead of thinking token budget
- Only show "1M Context" button for Sonnet 4.5
Also:
- Fixed bug where web/remote terminals weren't spawning in Electron
- Adds new
web_fetchtool so Mux agents can read URLs
v0.7.1
This is primarily a patch release to expose Opus 4.5. Note that users can always try models before we "release" them by inputting the full model string via /model <model> or the model selector UI.
Also:
v0.7.0
🪄 Features
Default model now set explicitly instead of defaulting to last used model:
Added light theme mode, toggled in top left:
Also:
- Integrated web terminal for SSH or browser-accessed workspaces (see coder/ghostty-web)
- "Tool: tool_name" AGENTS.md section for tool-specific instructions (docs)
- Support for Gemini 3.0 and Grok 4.1
🛠️ Fixes
- Optimized git status polling when you have dozens of workspaces
- Improved Anthropic caching
- Persisted costs/token usage across compaction cycles
v0.6.0
A major release with tons of goodies!
🪄 Features
Major: we have renamed the project from cmux to mux, but have taken great care in ensuring the migration is smooth for existing users. For example, we automatically symlink your old ~/.cmux directory to ~/.mux.
Tons of visual improvements on the UI, including revised agent sidebar and a more readable chat UI:
VS Code / Cursor extension for quickly jumping between IDE and Mux:
File extension icons:
The New Workspace flow has been reworked so that the workspace name is generated automatically from first message:
Also:
- Added an experimental Windows build to the release artifacts
- Added support for Ollama and OpenRouter (docs)
- Users may define model-specific system instructions with
Model: <model>in AGENTS.md (commit: 60b56ab, docs) - Messages now queue until end of content block, leading to better model performance when interrupting frequently
- This behavior seeks to mimic Claude Code to get the benefits of Anthropic's RL wrt interruptions
- Improved support for gpt-5.1-codex and the new mini model
- Updated the "codex" model abbreviation
- More robustness to 500s/404s on strange Responses API behavior
- Optimized file_edit tool calls to reduce bad edits and malformed files
🛠️ Fixes
- b6fb712: retry barrier should no longer occasionally flash in before a stream starts
- e74e229: workspace cost now persists across compaction
- Fixed bug where file_edit diffs occasionally had multiple scroll bars
- Fixed many bugs on the auto-retry system, less spammy, fewer nonsensical auto-retries (e.g. does not auto-retry model not found)
🐞 Known Issues
- Nothing major to speak of!
