Houston v0.4.25

Houston 0.4.25

New models

• Claude Sonnet 5. Anthropic's newest Sonnet is now in the chat model
  picker. It brings stronger agentic coding and tool use. Pick it per agent or
  per mission.
• More OpenAI Codex models. The Codex picker now lists three more models so
  you can match the model to the job:
  • GPT-5.4, a strong model for everyday coding.
  • GPT-5.4-Mini, small, fast, and cost-efficient for simpler tasks.
  • GPT-5.3-Codex-Spark, an ultra-fast coding model.

Before you upgrade

• Mac: quit Houston before installing. macOS does not always replace a
  running app cleanly. If in doubt, remove /Applications/Houston.app and drag
  the new copy in.
• Windows x64: auto-update from 0.4.7 or later pulls you forward
  automatically. The MSI is still not OS-code-signed, so Windows SmartScreen may
  warn on a fresh install.
• Windows ARM64: there is no auto-update path from an emulated x64 install.
  Download the ARM64 MSI manually, uninstall the x64 build first, then install
  the ARM64 one.
