 ## [Unreleased]
 
+### New Features
+
+- **Unified model runtime and provider authentication** — `ModelRuntime` centralizes model configuration, provider-owned `/login`, and dynamic provider catalogs. See [Providers](docs/providers.md).
+- **Live model catalog refresh** — `/model` refreshes configured providers in the background, and `pi update --models` forces an immediate refresh. See [Install and Manage](docs/packages.md#install-and-manage).
+- **xAI device-code OAuth and Grok 4.5 Responses support** — Sign in to xAI with a device code and use Grok 4.5 with low, medium, or high thinking. See [xAI](docs/providers.md#xai-grokx-subscription).
+
 ### Breaking Changes
 
 - Replaced the SDK's `CreateAgentSessionOptions.authStorage` and `modelRegistry` options with the async `modelRuntime` option. `AuthStorage` and its storage backends are no longer exported; use `ModelRuntime` (or a custom pi-ai `CredentialStore`), or `readStoredCredential()` for one-off reads of auth.json.

 - Added file-backed dynamic catalogs in `models-store.json`, per-provider pi.dev catalog overlays, and Radius gateway support including offline migration from legacy credential-cached catalogs.
 - Added extension provider `refreshModels(context)` support for dynamic model discovery with optional provider-controlled persistence.
 - Added `pi update --models` to force an immediate model catalog refresh without updating pi or extensions.
+- Added inherited xAI device-code OAuth login and Grok 4.5 OpenAI Responses support, with low, medium, and high thinking levels ([#6651](https://github.com/earendil-works/pi-mono/pull/6651) by [@Jaaneek](https://github.com/Jaaneek)).

 - Fixed configured-provider catalog refresh to parse pi.dev's model-ID keyed responses, throttle checks to once per four hours, send the versioned pi user agent, treat unimplemented routes as unavailable overlays, and show concise refresh status in `/model`.
 - Fixed adjacent assistant thinking blocks to render as one thinking section.
+- Fixed inherited OpenAI Codex session IDs longer than 64 characters to meet the API limit ([#6630](https://github.com/earendil-works/pi-mono/issues/6630)).
+- Fixed inherited terminal output to normalize tab characters consistently ([#6697](https://github.com/earendil-works/pi-mono/pull/6697) by [@xz-dev](https://github.com/xz-dev)).
+- Fixed the Windows terminal title after checking npm packages ([#6629](https://github.com/earendil-works/pi-mono/issues/6629)).
