### Changed
- Added `Ctrl+J` as a default newline keybinding alongside `Shift+Enter`.
- Renamed the displayed `zai` provider label to ZAI Coding Plan (Global) for clarity ([#5965](https://github.com/earendil-works/pi/issues/5965)).
- pi-ai's old global API (`stream`/`complete`/`completeSimple`, `getModel`/`getModels`/`getProviders`, `registerApiProvider`, `getEnvApiKey`, ...) moved off the `@earendil-works/pi-ai` root entrypoint to `@earendil-works/pi-ai/compat`. Extensions are not affected at runtime: the extension loader resolves the pi-ai root to the compat entrypoint (a strict superset), so existing extensions keep working unchanged. Extension sources that typecheck against pi-ai's published types should switch those imports to `@earendil-works/pi-ai/compat` (or migrate to the new `createModels()`/provider-factory API). The compat entrypoint and the loader alias will be removed in a future release with a migration guide.
### Fixed
- Fixed session names to normalize newline characters before storing or displaying labels ([#5999](https://github.com/earendil-works/pi/pull/5999) by [@haoqixu](https://github.com/haoqixu)).
- Fixed the session selector to order threaded session trees by the latest activity anywhere in each subtree ([#5784](https://github.com/earendil-works/pi/pull/5784) by [@Perlence](https://github.com/Perlence)).
- Fixed extension-related crash and startup-failure reporting to suggest restarting with `pi -ne`.
- Fixed inherited OpenAI Responses streams to fail before missing terminal events and fixed context usage and compaction estimates to ignore malformed all-zero assistant usage after truncated responses ([#5526](https://github.com/earendil-works/pi/pull/5526) by [@dmmulroy](https://github.com/dmmulroy)).
- Fixed inherited OpenAI Codex Responses WebSocket sessions to reconnect once when OpenAI's connection limit is reached before output starts ([#5973](https://github.com/earendil-works/pi/issues/5973)).
- Fixed inherited Amazon Bedrock endpoint resolution to honor scoped `AWS_PROFILE` values.
- Fixed inherited Cloudflare providers to require account/gateway configuration and route built-in compat calls through provider auth.
- Fixed provider-scoped auth environment values to reach inherited `Models`/`ImagesModels` API calls and compat API-key injection.
- Fixed inherited OpenCode Go GLM-5.2 metadata to expose `xhigh` reasoning and send the provider's max reasoning effort ([#5967](https://github.com/earendil-works/pi/issues/5967)).
- Fixed `pi --resume` to load user package themes and resolve automatic light/dark theme settings.
- Fixed `models.json` custom providers so stored credentials can satisfy auth without a redundant provider-level `apiKey` ([#5953](https://github.com/earendil-works/pi/issues/5953)).
### Removed
- Removed inherited selective-provider `@earendil-works/pi-ai/base` and `@earendil-works/pi-agent-core/base` entrypoints; use the root packages with explicit `Models` provider factories instead.
