Command-Line Interface Changes

  • Fatal error messages are now printed to both stderr and the logs. #17675

Bug Fixes

  • Foreign keys that point to a prefix of an existing index now work correctly. Previously, rows could be deleted from the referenced table without recognizing the constraint violation if rows in the referring table pointed to them. These foreign keys are also now shown correctly in SHOW CREATE TABLE. #17653
  • The crash reporter will now time out instead of waiting indefinitely trying to reach the server. #17689
  • AS OF SYSTEM TIME 0 is now a normal error instead of a panic. #17681
  • Fixed a panic caused by unclosed planNodes. #17281
  • 3DES has been removed from the list of supported TLS cipher suites (it would never be selected because we require TLS 1.2, but it could be reported as a false positive by security scanners). #17237

Performance Improvements

  • Reduced unhelpful retries of slow commands. #17385

Doc Updates

  • Added an FAQ on why CockroachDB uses the PostgreSQL wire protocol instead of the MySQL protocol. #1845
  • Added a known limitation around dropping an index interleaved into another index on the same table. #1859
