General Changes

SQL Language Changes

Command-Line Changes

  • The cockroach sql command no longer prompts for a password when a certificate is provided. #26232
  • The cockroach quit command now prints warning messages to the standard error stream, not to standard output. #26163

Bug Fixes

  • Prevented the internal gossip network from being partitioned by making it much less likely that nodes in the network could forget about each other. #25521
  • Prevented spurious BudgetExceededErrors for some queries that read a lot of JSON data from disk. #25719
  • Fixed a crash in some cases when using a GROUP BY with HAVING. #25654
  • Fixed a crash caused by inserting data into a table with computed columns that reference other columns that weren't present in the INSERT statement. #25807
  • UPSERT is now properly able to write NULL values to every column in tables containing more than one column family. #26181
  • Fixed a bug where a long-running query running from one day to the next would not always produce the right value for current_date(). #26413
  • Fixed a bug where cockroach quit would erroneously fail even though the node already successfully shut down. #26163
  • Rows larger than 8192 bytes are now supported by the "copy from" protocol. #26641
  • Trying to "copy from stdin" into a table that doesn't exist no longer drops the connection. #26641
  • Previously, expired compactions could stay in the queue forever. Now, they are removed when they expire. #26659

Performance Improvements

  • The performance impact of dropping a large table has been substantially reduced. #26615
