v1.0.0-beta.4

Release date: December 29, 2025

👍 Highlights

This version applies database-level compaction options to existing tables that don't have table-level compaction options. Now users don't have to set compaction options manually for each table if they want to adjust them.

There are also some important bug fixes:

• Panic when sorting on the time index column.
• The experimental flat format may create incorrect index files.

It's recommended to upgrade to this version.
