 ## [Unreleased]
 
+### New Features
+
+- Added OpenCode Go provider support with `opencode-go` model defaults and `OPENCODE_API_KEY` environment variable support ([docs/providers.md](docs/providers.md), [#1757](https://github.com/badlogic/pi-mono/issues/1757)).
+- Added `branchSummary.skipPrompt` setting to skip branch summarization prompts during tree navigation ([docs/settings.md](docs/settings.md), [#1792](https://github.com/badlogic/pi-mono/issues/1792)).
+- Added `gemini-3.1-flash-lite-preview` fallback model availability for Google provider catalogs when upstream model metadata lags ([README.md](README.md), [#1785](https://github.com/badlogic/pi-mono/issues/1785)).
+
 ### Breaking Changes
 
 - Changed scoped model thinking semantics. Scoped entries without an explicit `:<thinking>` suffix now inherit the current session thinking level when selected, instead of applying a startup-captured default.
+- Moved Node OAuth runtime exports off the top-level `@mariozechner/pi-ai` entry. OAuth login and refresh must be imported from `@mariozechner/pi-ai/oauth` ([#1814](https://github.com/badlogic/pi-mono/issues/1814)).
+
+### Added
+
+- Added `branchSummary.skipPrompt` setting to skip the summary prompt when navigating branches ([#1792](https://github.com/badlogic/pi-mono/issues/1792)).
+- Added OpenCode Go provider support with `opencode-go` model defaults and `OPENCODE_API_KEY` environment variable support ([#1757](https://github.com/badlogic/pi-mono/issues/1757)).
+- Added `gemini-3.1-flash-lite-preview` fallback model availability in provider catalogs when upstream catalogs lag ([#1785](https://github.com/badlogic/pi-mono/issues/1785)).
+
+### Changed
+
+- Updated Antigravity Gemini 3.1 model metadata and request headers to match upstream behavior.
 
 ### Fixed
 
 - Fixed IME hardware cursor positioning in the custom extension editor (`ctx.ui.editor()` / extension editor dialog) by propagating focus to the internal `Editor`, preventing the terminal cursor from getting stuck at the bottom-right during composition.
-- Added OSC 133 semantic zone markers around rendered user messages to support terminal navigation between prompts in iTerm2, WezTerm, Kitty, Ghostty, and other compatible terminals ([#1805](https://github.com/badlogic/pi-mono/issues/1805))

+- Fixed markdown blockquotes dropping nested list content in the TUI renderer ([#1787](https://github.com/badlogic/pi-mono/issues/1787)).
+- Fixed TUI width handling for regional indicator symbols to prevent wrap drift and stale characters during streaming ([#1783](https://github.com/badlogic/pi-mono/issues/1783)).
+- Fixed Kitty CSI-u handling to ignore unsupported modifiers so modifier-only events do not insert printable characters ([#1807](https://github.com/badlogic/pi-mono/issues/1807)).
+- Fixed single-line paste handling to insert text atomically and avoid repeated `@` autocomplete scans on large pastes ([#1812](https://github.com/badlogic/pi-mono/issues/1812)).
+- Fixed extension loading with the new `@mariozechner/pi-ai/oauth` export path by aliasing the oauth subpath in the extension loader and development path mapping ([#1814](https://github.com/badlogic/pi-mono/issues/1814)).
+- Fixed browser-safe provider loading regressions by preloading the Bedrock provider module in compiled Bun binaries and rebuilding binaries against fresh workspace dependencies ([#1814](https://github.com/badlogic/pi-mono/issues/1814)).
+- Fixed GNU screen terminal detection by downgrading theme output to 256-color mode for `screen*` TERM values ([#1809](https://github.com/badlogic/pi-mono/issues/1809)).
+- Fixed branch summarization queue handling so messages typed while summaries are generated are processed correctly ([#1803](https://github.com/badlogic/pi-mono/issues/1803)).
+- Fixed compaction summary requests to avoid reasoning output for non-reasoning models ([#1793](https://github.com/badlogic/pi-mono/issues/1793)).
+- Fixed overflow auto-compaction cascades so a single overflow does not trigger repeated compaction loops.
+- Fixed `models.json` to allow provider-scoped custom model ids and model-level `baseUrl` overrides ([#1759](https://github.com/badlogic/pi-mono/issues/1759), [#1777](https://github.com/badlogic/pi-mono/issues/1777)).
+- Fixed session selector display sanitization by stripping control characters from session display text ([#1747](https://github.com/badlogic/pi-mono/issues/1747)).
+- Fixed Groq Qwen3 reasoning effort mapping for OpenAI-compatible models ([#1745](https://github.com/badlogic/pi-mono/issues/1745)).
+- Fixed Bedrock `AWS_PROFILE` region resolution by honoring profile `region` values ([#1800](https://github.com/badlogic/pi-mono/issues/1800)).
+- Fixed Gemini 3.1 thinking-level detection for `google` and `google-vertex` providers ([#1785](https://github.com/badlogic/pi-mono/issues/1785)).
+- Fixed browser bundling compatibility for `@mariozechner/pi-ai` by removing Node-only side effects from default browser import paths ([#1814](https://github.com/badlogic/pi-mono/issues/1814)).
