Claude Code v2.1.229 12 Aug 2026

Diff sidebar failures no longer take down the view

You'll notice

Useful3 Signal1

An error drawing the diff sidebar no longer breaks your whole session view.

What

A rendering error in the diff sidebar is now caught and reported rather than escaping and breaking the session view.

Details

Reported as repl_diff_read / render_threw, with the React component stack hashed when one is present.

Evidence

render_threw

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
