Houston v0.4.26

Houston 0.4.26

Models

• Claude Sonnet 5 runs with a full 1M context window. That is a full million
  tokens of context on every message, so long missions hold much more of their
  history.
• Fable 5 is in the model picker. Pick it per agent or per mission.

Now in your language

• The new-agent store speaks Spanish and Portuguese. The built-in agents and
  the model picker inside the store now follow your app language, so the whole
  store reads in Spanish or Portuguese.

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.
