Houston v0.4.27

Houston 0.4.27

Models

• GPT-5.6 Sol, Terra, and Luna are in the model picker. OpenAI's newest
  family, released July 9. Pick them per agent or per mission.
• All three unlock the new "max" reasoning level. The deepest thinking
  OpenAI offers, for the hardest problems.

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.
