Bug fixes

• Corrected the replicas count for table details in the Admin UI. #49206
• The rolcanlogin value for roles is now correctly populated in pg_roles and pg_catalog. #49622
• Fixed a rare bug in the Pebble storage engine that could lead to storage engine inconsistencies. #49378
• Corrected how engine type is reported in bug reports when using cockroach demo. #49377
• Fixed a bug where cockroach quit would not proceed to perform a hard shutdown when the value passed to --drain-wait was very small, but non-zero. This bug existed since v19.1.9, v19.2.7 and v20.1.1. #49363
• Fixed a bug where \demo node restart would not work due to an invalid certificate directory. #49390
• Fixed some benign errors that were being reported as unexpected internal errors by the vectorized execution engine. #49534
• Fixed a rare bug in the Pebble storage engine where keys were being returned out-of-order from large sstable files. #49602
• When run via the vectorized execution engine, queries with a hash routed in the DistSQL plan no longer return an internal error or incorrect results. #49624
• When run via the vectorized execution engine, queries that have columns of the BYTES type in the output no longer result in an internal error. #49384
• CockroachDB no longer leaks file descriptors during GSS authentication. #49614
• Attempting to perform a full cluster RESTORE on a backup that did not contain any user data no longer fails. #49745
• Abandoned intents due to failed transaction coordinators are now cleaned up much faster. This resolves a regression in v20.1.0 compared to prior releases. #49835
• Fixed the descriptions for --socket-dir and --socket in the CLI help. They were incorrect since v20.1.0. #49906
• Adjusted Pebble's out of memory error behavior to match that of the Go runtime in order to make the condition more obvious. #49874
• When performing incremental backups with revision history on a database (or full cluster), and a table in the database was dropped and then other tables were later created, the backup no longer returns an error. #49925
• Fixed an internal planning error for recursive CTEs (WITH RECURSIVE expressions) in which the left side of the UNION ALL query used in the CTE definition produced zero rows. #49964

Doc updates

• Added a CockroachCloud Quickstart on creating and connecting to a 30-day free CockroachCloud cluster and running your first query. #7454
• Updated the Active Record tutorial to use a new CockroachDB adapter version. #7480
• Changed instances of "whitelist"/"blacklist" to "allowlist"/"blocklist" throughout the documentation. #7479
• Updated all mentions of range_min_size and range_max_size to use the new default values of 134217728 and 536870912, respectively. #7449
• Updated the hardware storage recommendations. #7514
