 ## [Unreleased]
 
-Add user-visible changes here before running `bun run release:prepare <version>`.
+### Added
+
+- **Claude Opus 5, GPT-6 Astra, GPT-5.6, GLM-5.3, DeepSeek V4 Pro and about
+  300 other models are now selectable.** The bundled Pi SDK moved from 0.80.6
+  to 0.85.1, which brings its model catalog up to date (1057 → 1354 entries)
+  and adds four providers, including Baseten and the Qwen token plans. Models
+  appear under the connection you already have; no reconfiguration needed.
+
+### Fixed
+
+- **ChatGPT Plus sign-in and token refresh work again in packaged builds.**
+  Every request through a ChatGPT subscription could fail with
+  `Cannot find module './openai-codex.js'` because the SDK's OAuth flows are
+  loaded lazily and the packaged agent could not find them. They are now
+  registered up front.
+
+### Changed
+
+- The agent's credential layer now runs on the Pi SDK's `ModelRuntime` API.
+  Subscription tokens refreshed by the SDK are still mirrored back to the
+  desktop app, so sessions keep working past token expiry without a new
+  sign-in.
+- Documentation no longer advertises a Claude Pro/Max subscription flow. That
+  option was never implemented; ChatGPT Plus is the only subscription sign-in.

 # Bitlab documentation (English)
 
-Bitlab is a cross-platform, local-first AI agent workspace derived from [Craft Agents OSS](https://github.com/craft-ai-agents/craft-agents-oss) `v0.11.2`. The current runtime is Pi-only: `@earendil-works/pi-coding-agent` runs in a dedicated Bun subprocess and serves the Electron app, WebUI, CLI, and headless server through one RPC contract. Bitlab supports API-key connections, custom OpenAI/Anthropic-compatible endpoints, Ollama, and the retained ChatGPT Plus / Claude Pro/Max subscription flows. It does not include the Claude Agent SDK, GitHub Copilot, external messaging, product automations, Projects/Kanban, Sources/MCP, Viewer/public sharing, or image generation.
