Unclear It is not clear what switches the new delete mode on, or whether it is on by default.

What

Memory sync keeps Claude's memory files in step across several stores. While it writes, it now holds a guard on the file. If a tool is still using that file, the write is skipped.

Other changes:

  • The notice after a pull now says it kept local files that changed or were in use during the pull.
  • The check for whether deletions are pushed out has a second way to be switched on.
  • When memory sync is not sending changes, its notice warns that a delete has probably not gone out. Before, this warning appeared only when a separate switch was on.
Why

Memory files are less likely to be overwritten while in use, and Claude gets a more honest notice when a deletion has not been sent.
