- **Frontend integrations:** Unix v2 supports application-provided tools and skills. Companion and Linux verification remain pending.
### Fixes
Improved image rendering, response recovery, subagent history, authentication, and file safety.
### Breaking changes
- Removed `--app service` and stdio v1. Frontends must use Unix v2.
- Moved primary-agent profiles to `$MC_HOME/agents/`. Automatic migration applies when that directory does not exist.
