Bug fixes

• Fixed corrupted documents being read silently from disk without checksum validation.
• Fixed database getting stuck when a batch insert fails halfway through.
• Fixed compact() not actually freeing disk space in single-file mode.
• Fixed index values greater than 2 billion being corrupted after a restart.
• Fixed memory growing unboundedly after many deletes or updates.
• Fixed nested transaction() calls silently corrupting rollback state — now throws a clear error.
• Fixed calling beginTransaction() twice discarding pending writes silently — now throws a clear error.
• Fixed watch() streams accumulating in memory after all listeners are gone.
• Fixed registering two adapters with the same typeId silently overwriting the first one — now throws an error.

New features

• DateTime is now supported natively — no more manual conversion needed.

Improvements

• Queries are noticeably faster: the query planner no longer runs each condition twice to estimate cost.
• startsWith() is now much faster on sorted indexes (uses a range scan instead of scanning everything).
