What's New

Adds mosh transport support and new AI models while fixing web UI grouping and Codex session handling.

New Features

Remote attaches now support mosh transport for high-latency links.
Claude Opus 5.5 model is now available.
GPT-6 series models are now available.
Codex sessions now accept --effort max and --effort ultra flags.

Bug Fixes

Web sidebar now nests subgroups and sessions correctly and syncs collapse state with the TUI.
Codex session busy state handling is fixed.

Upgrade Notes

Configure `transport = "mosh"` in `config.toml` to enable the new remote attach feature, and update model strings if relying on the default Claude model (now Opus 5.5). Codex sessions now accept `--effort max` and `--effort ultra`.
