# 0.2.54

## Features

- **Rewind** now works end-to-end across conversation and file state with proper CAS handling.

## Bug Fixes

- **Git branch icons** now render correctly on Windows without Nerd Fonts.
- **Mermaid diagrams** now render inline without the model suggesting external viewers.
- MCP connection errors now show the actual failure reason to the model.
- MCP servers with noisy stdout no longer disconnect unexpectedly.
- **Usage warnings** now always display "Usage left: N%" instead of varying between "Free credits left" and "Credits left".
- **Window title** no longer flashes or oscillates during permission prompts while the terminal window is focused.

## Performance

- **Fixed pager freezes** and 100% CPU usage when rendering very long agent reasoning outputs with thousands of styled spans.
