What probably matters to youSection of the release

What

Setting CLAUDE_BG_BACKEND=daemon now makes the terminal renderer tolerate stdout going away instead of treating it as fatal.

Details

The terminal wrapper tracks whether tolerance is on and whether stdout has already died.
Separately, the warnings about garbage or absurd terminal dimensions moved from a once-per-process flag to a per-renderer callback, so a second renderer can still warn.

Evidence

tolerateDeadStdout: re.CLAUDE_BG_BACKEND === "daemon"

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