What probably matters to you Section of the release
What
Whether directory sync streams changes is decided by CLAUDE_CODE_DIR_SYNC_STREAM . The check is an inversion, so streaming runs unless the variable is set to turn it off.
Details
The surrounding sync feature is not otherwise exposed in this build, so the variable matters only where sync is active.
