What
In Cowork, Claude keeps memory it can read and write with a memory tool. Claude Code keeps a record of those memory tool calls, and that record changed in three ways:
- It now notes the
if_versionvalue given with a write. - It keeps the last version and a carried-over version for each memory path. Before, it tracked only which paths were read and which were written.
- A new warning is logged when passing these versions along fails.
Why
This lets memory writes be checked against a version from one turn to the next.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
It is unclear what switches this on and what uses the recorded versions.
