General changes

SQL language changes

• In a mixed-version cluster, nodes running v2.0 no longer schedule distributed SQL work on nodes running v2.1. #29168
• When TRUNCATE or DROP TABLE is run while a schema change like CREATE INDEX is being processed, the schema change job no longer runs indefinitely. #29262

Command-line changes

• The new cockroach workload command provides various generators for data and query loads. #28978
