Shared (all surfaces)

Features

• GPT-5.6 is now the default model — new conversations start with GPT-5.6
  instead of Sonnet 5, and it leads the model picker. Existing selections are
  unchanged.
• Gemini 3.8 Flash is available — the new Flash model replaces Gemini 3.7
  Flash in the default model list with improved reasoning and coding at the
  same introductory price. Existing selections of Gemini 3.7 Flash keep
  working while Google serves them.
• Muse Spark 1.3 is available — Meta's latest standard model joins the
  default model list with a 1M-token context window, multimodal input, prompt
  caching, web search, and configurable reasoning. Existing selections of Muse
  Spark 1.1 keep working while Meta serves them.
• Claude Fable 5.1 is available — Fable 5.1 replaces Fable 5 in the
  default model list, and the Claude Code agent tool now selects Fable 5.1.
  Existing Fable 5 selections keep working while Anthropic serves them.

Improvements

• Font Awesome Free icons are properly attributed — the shipped products
  now carry the required CC BY 4.0 attribution in their NOTICE files.

Bug Fixes

• Prevent crashes in long-running sessions — sessions that run many
  subagents no longer exhaust memory and crash. Finished child agents now
  release their records on the CLI as well as in the extension and desktop
  app.
• Voice recordings transcribe reliably — finishing a recording no longer
  risks an empty or failed transcription when the audio file takes a moment to
  finish writing.
• A failed start no longer blocks later runs — when a run fails to launch,
  its slot is released so later starts on the same conversation work instead
  of being refused.
• Explain failed external-tool checks — the Tools dashboard now distinguishes
  a broken availability check from a tool that is simply not installed.

Extension (VS Code)

Bug Fixes

• Archive custom-agent output on Windows — packing generated files into the
  History folder now works for custom agents.

Extension (VS Code) and Desktop

Bug Fixes

• Resuming a run explains failures — when TeXRA refuses to resume a run,
  the extension and desktop app now show the reason instead of failing
  silently.

CLI

Bug Fixes

• Exiting an idle run no longer cancels it — /exit now follows the same
  quit policy as Ctrl-C, so leaving an idle conversation keeps it resumable
  instead of cancelling it and clearing pending approvals.
• Unavailable runs explain why they cannot accept input — the composer now
  shows when another TeXRA process holds the run or its saved state is unreadable.
