earendil-works/pi (earendil-works/pi)

v0.85.1

Compare Source

New Features

• GPT-6 Astra — Available through OpenAI API keys and OpenAI Codex subscriptions. See API Keys and OpenAI Codex.

Added

• Added GPT-6 Astra for OpenAI API keys and OpenAI Codex subscriptions.
• Added five-times-faster mouse wheel scrolling while holding Alt in fullscreen mode (#​9166 by @​xl0).

Fixed

• Fixed configurable save keybindings in the model and thinking selectors (#​9149 by @​rwachtler).
• Fixed SDK import failures caused by unintentionally publishing internal experimental code and dependencies in 0.85.0. The experimental client and experimental/plugin subpaths and server/client commands are now source-only through pi-test.sh; the supported local SDK and stdio RPC API are unchanged (#​9132).
• Fixed mouse hover changing selection and recentering autocomplete and settings lists, causing clicks to target a different item.
• Fixed long prompt-cache requests for GPT-5.6+ Responses models to use prompt_cache_options.ttl: "30m" instead of prompt_cache_retention: "24h".
