Houston 0.4.20

Claude Fable 5, Anthropic's most capable model, is now a pick for your agents. Plus a simpler way to set custom routine schedules and a couple of chat fixes. Drop-in on top of 0.4.19, no breaking changes.

Added

  • Claude Fable 5. Fable 5 is Anthropic's most capable model, and you can now choose it for any agent from the model picker. It is the strongest option for hard, multi-step work. One thing to know about cost: Fable 5 uses about twice the credits of Opus 4.8 per run, so reach for it when a task really calls for it and keep Opus 4.8 or Sonnet 4.6 for everyday work.
  • Simpler custom routine schedules. Setting a custom schedule is now a plain "Repeat every N minutes, hours, days, weeks, or months" picker instead of anything cron-shaped. Choose weeks and you get a day-of-week selector with Every day, Weekdays, and Weekends shortcuts. Choose months and you pick the day of the month. The plain-language summary updates as you go, so you always see exactly when the routine will run.
  • Routines now speak Spanish and Portuguese. The Routines tab, the schedule builder, run history, and the plain-language schedule summaries are all translated, so routines read in your language from end to end.

Changed

  • Clearer model descriptions. Every Claude model in the picker now has a refreshed one-line description, so the trade-off between speed, capability, and cost reads at a glance.

Fixed

  • Links in chat are clickable. A plain web address an agent writes in chat now opens in your browser with a single click, no copy and paste.
  • Codex no longer interrupts during a web search. Fixed an error that could break a Codex chat while it was searching the web.
  • No more flashing Claude sign-in dialog on desktop. A sign-in dialog meant for the web and mobile apps used to flash on screen and dismiss itself when you connected Claude on desktop. It no longer appears there.

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 (SignPath integration still pending), 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.

Known limitations

  • Fable 5 costs more credits. It uses roughly twice the credits of Opus 4.8 per run. The model picker flags this, but it is worth knowing before you switch every agent over.
