v1.1.1

· 阅读需 1 分钟

Release date: June 18, 2026

This release fixes a critical JSON compatibility bug that affects users upgrading from v1.0.x to v1.1.0, where legacy JSONB columns could return incorrect query results or fail during flush. It also removes a lock in the create flow procedure that could self-block sink table creation.

We strongly recommend users on v1.1.0 who use the JSON data type upgrade to v1.1.1.
