Claude Code v2.1.181 17 Jun 2026

Improved In-Place Write Fallback with Content Preservation

The file-write fallback path now preserves content in the temporary file if an in-place overwrite fails after the target has been truncated, giving you a chance to recover data. The error message now points you to the temp file path.

Error text: "writeFileAndFlush: in-place fallback write failed; content preserved at temp path" / "writeFileSyncAndFlush: in-place fallback write failed; content preserved at temp path"

Evidence

Content-preservation fallback (search for "content preserved at temp path") — hfr() at line ~55659, aEt() at line ~55513

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