Version 6.2.7

Released on 2026-04-27.

Note

If you are upgrading a cluster, you must be running CrateDB 5.0.0 or higher before you upgrade to 6.2.7.

We recommend that you upgrade to the latest 6.1 release before moving to 6.2.7.

A rolling upgrade from >= 6.1.2 to 6.2.7 is supported. Doing a rolling upgrade from an earlier version than 6.1.2 can cause runtime errors when executing statements relying on implicit casts.

Before upgrading, you should back up your data.

Warning

Tables that were created before CrateDB 5.x will not function with 6.x and must be recreated before moving to 6.x.x.

You can recreate tables using COPY TO and COPY FROM or by inserting the data into a new table.

See the Version 6.2.0 release notes for a full list of changes in the 6.2 series.

Fixes

  • Fixed an issue that caused the statement_timeout setting to expire a query if a PostgreSQL client was idling between creating a prepared statement (sending a parse message) and using the prepared statement (sending bind or execute messages).
