## New Features
- Added a `/permissions` command with a shorter approval set while keeping `/approvals` for compatibility. (#9561)
- Added a `/skill` UI to enable or disable individual skills. (#9627)
- Improved slash-command selection by prioritizing exact and prefix matches over fuzzy matches. (#9629)
- App server now supports `thread/read` and can filter archived threads in `thread/list`. (#9569, #9571)
- App server clients now support layered `config.toml` resolution and `config/read` can compute effective config from a given cwd. (#9510)
- Release artifacts now include a stable URL for the published config schema. (#9572)
## Bug Fixes
- Prevented tilde expansion from escaping HOME on paths like `~//...`. (#9621)
- TUI turn timing now resets between assistant messages so elapsed time reflects the latest response. (#9599)
## Documentation
- Updated MCP subcommand docs to match current CLI behavior. (#9622)
- Refreshed the `skills/list` protocol README example to match the latest response shape. (#9623)
## Chores
- Removed the TUI2 experiment and its related config/docs, keeping Codex on the terminal-native UI. (#9640)
