###### New Features

- **GPT-6 Astra** — Available through OpenAI API keys and OpenAI Codex subscriptions. See [API Keys](https://github.com/earendil-works/pi/blob/v0.85.1/packages/coding-agent/docs/providers.md#api-keys) and [OpenAI Codex](https://github.com/earendil-works/pi/blob/v0.85.1/packages/coding-agent/docs/providers.md#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](https://github.com/earendil-works/pi/pull/9166) by [@xl0](https://github.com/xl0)).

###### Fixed

- Fixed configurable save keybindings in the model and thinking selectors ([#9149](https://github.com/earendil-works/pi/pull/9149) by [@rwachtler](https://github.com/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](https://github.com/earendil-works/pi/issues/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"`.
