## What changed


- **Provider-scoped API key environments**: `auth.json` entries can now include `env` overrides for provider-specific Cloudflare, Azure OpenAI, Google Vertex, Amazon Bedrock, cache retention, and proxy settings
- **Global HTTP proxy**: `httpProxy` setting in global config applies `HTTP_PROXY`/`HTTPS_PROXY` to Pi-managed HTTP clients
- **Vercel AI Gateway attribution**: requests include `http-referer` and `x-title` headers by default
- **Added**: `xp` footer marker when experimental features are enabled
- **Updated**: vendored Markdown parser to `marked` 18.0.5
- **Fixes**: OpenAI Responses streaming null content before tool calls, DeepSeek V4 thinking payload conflict, device-code login browser auto-open, Cursor Up draft handling, Z.AI GLM-5.2 reasoning effort mapping, Windows `pi update` exit crash, Google/Vertex Gemini model metadata (Gemini 3.5 Flash, cache pricing, removed preview models), session selector empty state, Moonshot Kimi K2.7 Code model metadata and thinking-off payloads
