For detailed release notes, see individual component repositories:

• Server Releases
• Runtime Releases
• CLI Releases
• OneLLM Releases

February 2026

Local Development Mode

Fast iteration without full deploy cycle:

• Server: /rpc/dev/run and /rpc/dev/stop endpoints, /draft/{id}/* proxy route
• CLI: muxi up [path] to start local formation, muxi down to stop
• SDKs: mode parameter ("live" or "draft") to switch between live and draft formations
• Draft and live formations can run simultaneously with the same ID

SDK Update Notifications

Server now notifies SDKs when updates are available:

• Parses X-Muxi-SDK header from requests
• Responds with X-Muxi-SDK-Latest header containing latest version
• Fetches release versions from GitHub API (refreshes every 24h)

Bug Fixes

• Fixed Docker container naming for draft formations (use -draft suffix)
• Improved error messages when formations crash during startup (removed ASCII art noise)
