The last two noteworthy features and improvements in @sequel 2.5 are:
1. A new automatic backup system which runs quietly in the background
2. iCloud sync being up to 240x faster (yes, really)!

If you’re curious, the latter was partly achieved by switching to CKSyncEngine from NSPersistentCloudKitContainer, and re-architecting the database to get around CloudKit’s limitations and… quirks. This required a complete rewrite of the sync engine and literally months of work!
