What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

###### New Features

- **Persistent Claude thinking effort** — Supported Anthropic transports preserve per-turn effort and recover safely from signed-thinking mismatches. See [Model Configuration](https://github.com/earendil-works/pi/blob/v0.85.0/packages/coding-agent/docs/models.md#model-configuration).
- **Fullscreen transcript controls** — Jump to the latest message from a scrolled transcript and use the embedded working indicator. See [TUI Fullscreen Viewport](https://github.com/earendil-works/pi/blob/v0.85.0/packages/coding-agent/docs/keybindings.md#tui-fullscreen-viewport).
- **Restorable in-memory sessions** — Resume externally stored session entries through the SDK. See [Session Management](https://github.com/earendil-works/pi/blob/v0.85.0/packages/coding-agent/docs/sdk.md#session-management).

- Added `SessionManager.inMemory()` support for restoring externally managed session entries ([#8980](https://github.com/earendil-works/pi/pull/8980) by [@y-nk](https://github.com/y-nk)).
- Added inherited OpenAI-compatible `vllmPriority` and `supportsMaxOutputTokens` model settings for vLLM scheduler priority and OpenAI Responses output-token limits ([#9004](https://github.com/earendil-works/pi/pull/9004) by [@AppleDannyClegg](https://github.com/AppleDannyClegg), [#8941](https://github.com/earendil-works/pi/pull/8941) by [@scturtle](https://github.com/scturtle)).
