What probably matters to youSection of the release
What
Installing plugins in headless mode now re-fills the plugin cache after each change instead of leaving it stale, without blocking the install. Set CLAUDE_CODE_SYNC_PLUGIN_INSTALL to skip the background work entirely; it is also skipped when a cache-only load is already pinned.
Details
The re-fill is tracked so a later pass can tell whether the current cache came from its own refresh.
A failed refresh logs a tagged message rather than rejecting and failing the install.
Evidence
headlessPluginInstall: plugins changed
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
