 ### Fixed
 
+- Fixed nested code fences in the Termux setup documentation so the example AGENTS.md renders correctly ([#4503](https://github.com/earendil-works/pi/issues/4503)).
 - Fixed tool output expansion while extension confirmation dialogs are focused ([#4429](https://github.com/earendil-works/pi/issues/4429)).
 - Fixed auto-retry for Anthropic streams that end before `message_stop` ([#4433](https://github.com/earendil-works/pi/issues/4433)).
 - Fixed theme sharing across package scopes so extensions do not crash with `Theme not initialized` ([#4333](https://github.com/earendil-works/pi/issues/4333)).
