## [Unreleased] ## [Unreleased]
## [0.56.2] - 2026-03-05
### Added ### Added
- Added `gpt-5.4` model support for `openai`, `openai-codex`, `azure-openai-responses`, and `opencode` providers, with GPT-5.4 treated as xhigh-capable and capped to a 272000 context window in built-in metadata. - Added `gpt-5.4` model support for `openai`, `openai-codex`, `azure-openai-responses`, and `opencode` providers, with GPT-5.4 treated as xhigh-capable and capped to a 272000 context window in built-in metadata.
- Added `gpt-5.3-codex` fallback model availability for `github-copilot` until upstream model catalogs include it ([#1853](https://github.com/badlogic/pi-mono/issues/1853)).
### Fixed ### Fixed
- Preserved OpenAI Responses assistant `phase` metadata (`commentary`, `final_answer`) across turns by encoding `id` and `phase` in `textSignature` for session persistence and replay, with backward compatibility for legacy plain signatures ([#1819](https://github.com/badlogic/pi-mono/issues/1819)). - Preserved OpenAI Responses assistant `phase` metadata (`commentary`, `final_answer`) across turns by encoding `id` and `phase` in `textSignature` for session persistence and replay, with backward compatibility for legacy plain signatures ([#1819](https://github.com/badlogic/pi-mono/issues/1819)).
- Fixed OpenAI Responses replay to omit empty thinking blocks, avoiding invalid no-op reasoning items in follow-up turns.
- Switched the Mistral provider from the OpenAI-compatible completions path to Mistral's native SDK and conversations API, preserving native thinking blocks and Mistral-specific message semantics across turns ([#1716](https://github.com/badlogic/pi-mono/issues/1716)). - Switched the Mistral provider from the OpenAI-compatible completions path to Mistral's native SDK and conversations API, preserving native thinking blocks and Mistral-specific message semantics across turns ([#1716](https://github.com/badlogic/pi-mono/issues/1716)).
- Fixed Antigravity endpoint fallback: 403/404 responses now cascade to the next endpoint instead of throwing immediately, added `autopush-cloudcode-pa.sandbox` endpoint to the fallback list, and removed extra fingerprint headers (`X-Goog-Api-Client`, `Client-Metadata`) from Antigravity requests ([#1830](https://github.com/badlogic/pi-mono/issues/1830)). - Fixed Antigravity endpoint fallback: 403/404 responses now cascade to the next endpoint instead of throwing immediately, added `autopush-cloudcode-pa.sandbox` endpoint to the fallback list, and removed extra fingerprint headers (`X-Goog-Api-Client`, `Client-Metadata`) from Antigravity requests ([#1830](https://github.com/badlogic/pi-mono/issues/1830)).

### New Features
- GPT-5.4 support across `openai`, `openai-codex`, `azure-openai-responses`, and `opencode`, with `gpt-5.4` now the default for `openai` and `openai-codex` ([README.md](README.md), [docs/providers.md](docs/providers.md)).
- `treeFilterMode` setting to choose the default `/tree` filter mode (`default`, `no-tools`, `user-only`, `labeled-only`, `all`) ([docs/settings.md](docs/settings.md), [#1852](https://github.com/badlogic/pi-mono/pull/1852) by [@lajarre](https://github.com/lajarre)).
- Mistral native conversations integration with SDK-backed provider behavior, preserving Mistral-specific thinking and replay semantics ([README.md](README.md), [docs/providers.md](docs/providers.md), [#1716](https://github.com/badlogic/pi-mono/issues/1716)).
### Added
- Added `gpt-5.4` model availability for `openai`, `openai-codex`, `azure-openai-responses`, and `opencode` providers.
