Version 6.4.5 - Unreleased

Note

In development. 6.4.5 isn’t released yet. These are the release notes for the upcoming release.

Note

If you are upgrading a cluster, you must be running CrateDB 5.0.0 or higher before you upgrade to 6.4.5.

We recommend that you upgrade to the latest 6.3 release before moving to 6.4.5.

A rolling upgrade from >= 6.3.0 to 6.4.5 is supported. 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.

Fixes

  • Fixed an issue that could cause statements including a cross join and an outer join plus any other join to drop the outer join condition, leading to incorrect results.

  • Fixed an issue that caused casting string values to a longer bit string to fail with an StringIndexOutOfBoundsException instead of filling up the gap with 0.

  • Fixed an issue that caused casting null to the bit type to fail.

  • Fixed an issue that caused CrateDB to choose the wrong relation if a parent relation alias clashed with a local scoped relation name.

  • Fixed decoding of interval values sent from PostgreSQL wire protocol clients using text format in the x hours y minutes ... style.

  • Fixed an issue that could lead to out of memory errors if using the percentile aggregation.

  • Fixed an issue causing cache to retain some heavy structures, potentially leading to an OutOfMemoryError.
