1. Enhance cache synchronization security protection. It is not compatible with cache data from older versions. We recommend all users to upgrade to the latest version. All cache synchronization functions have been disabled in older versions; upgrading to the latest version is necessary to use them.

2. System settings and window configurations now include the options to delete cloud-based extension cache and query cloud-based extension cache.

3. Added validation for "Enable Extension Data Sync." Enabling extension data synchronization requires mandatory password input.

4. Temporarily disable the 'Sync Extension Data Across Browsers' feature, to be re-enabled after further enhancement and optimization.
