- Custom provider support via `pi.registerProvider()` with `streamSimple` for custom API implementations
- Added `custom-provider.ts` example extension demonstrating custom Anthropic provider with OAuth

### Fixed

- Extension `setWorkingMessage()` calls in `agent_start` handlers now work correctly; previously the message was silently ignored because the loading animation didn't exist yet ([#935](https://github.com/badlogic/pi-mono/issues/935))
- Off-by-one error in bash output "earlier lines" count caused by counting spacing newline as hidden content ([#921](https://github.com/badlogic/pi-mono/issues/921))

### Changed

- HTML export: clicking a sidebar message now navigates to its newest leaf and scrolls to it, instead of truncating the branch ([#853](https://github.com/badlogic/pi-mono/pull/853) by [@mitsuhiko](https://github.com/mitsuhiko))
- HTML export: active path is now visually highlighted with dimmed off-path nodes ([#929](https://github.com/badlogic/pi-mono/pull/929) by [@hewliyang](https://github.com/hewliyang))
- `/reload` now re-renders the entire scrollback so updated extension components are visible immediately
- Skill, prompt template, and theme discovery now use settings and CLI path arrays instead of legacy filters ([#645](https://github.com/badlogic/pi-mono/issues/645))

### Fixed

- Extension `setWorkingMessage()` calls in `agent_start` handlers now work correctly; previously the message was silently ignored because the loading animation didn't exist yet ([#935](https://github.com/badlogic/pi-mono/issues/935))
- Off-by-one error in bash output "earlier lines" count caused by counting spacing newline as hidden content ([#921](https://github.com/badlogic/pi-mono/issues/921))
- User package filters now layer on top of manifest filters instead of replacing them ([#645](https://github.com/badlogic/pi-mono/issues/645))
- Auto-retry now handles "terminated" errors from Codex API mid-stream failures
- Follow-up queue (Alt+Enter) now sends full paste content instead of `[paste #N ...]` markers ([#912](https://github.com/badlogic/pi-mono/issues/912))
