Binaries

Backwards-Incompatible Changes

• Time zone offsets are no longer shown when querying columns of type TIMESTAMP; the new type TIMESTAMP WITH TIME ZONE should be used instead. This is more consistent with other databases. #6165

New Features

• INTERVAL values accept two new formats: ISO8601 (P2H30M) and the PostgreSQL format (2 hours 30 minutes) in addition to the existing Go style (2h30m). #6216
• Tuples can now be compared in SQL expressions. #6217
• The server now implements the systemd NOTIFY_SOCKET protocol. #6268
• The new flag cockroach start --background can be used to start a server in the background. This is better than appending & because the process doesn't return until it is ready to receive traffic. #6268

Bug fixes

• The SQL shell can once again be suspended with ctrl-z. #6171
• Fixed an error in the SQL shell when the history file contains empty lines. #6192
• The --store and --key-size command-line flags are no longer marked as required. #6229
• The command line interface is better about printing errors to stderr, not just the log file. #6258
• The INFO log file is now created in the correct default location (cockroach-data/logs) instead of $TMPDIR. #6265
• Fixed errors that could be introduced by updating tables while a schema change is in progress. #6160
• Fixed several potential panics. #6187, #6235, #6242

Performance Improvements

• Raft processing is no longer blocked while generating a snapshot for a new replica. #6253
