Added the INCLUDE_DEPRECATED_INTERLEAVES option to BACKUP. In v21.1, this option must be specified when backing up a cluster, database, or table that includes interleaved data. #64688
Added the chunk_size option to EXPORT CSV to control the target CSV file size. #65009

The --help text for --max-disk-temp-storage now properly reports the default value. #55055

Implemented a new library for line graphs that renders metrics more efficiently. Customers with large clusters (above ~30 nodes) can now load and interact with the metrics dashboards much faster than before. #64493
A legend is now shown underneath a timeseries graph if more than 10 series are being displayed. #64493

Fixed a race condition where read-write requests during replica removal (for example, during range merges or rebalancing) could be evaluated on the removed replica. These cases would not result in data being written to persistent storage, but could result in errors that should not have been returned. #64601
Fixed a stack overflow that could happen in some corner cases involving partial indexes with predicates containing (x IS NOT NULL). #64739
Building no longer depends on internet access. Only vendored modules are used. This bug was introduced in v20.2.0. #64507
Limit scans are no longer counted as full scans. #64852
Providing a constant value as an ORDER BY value in an ordered set aggregate, such as percentile_dist or percentile_cont, no longer errors. This bug has been present since order set aggregates were added in v20.2.0. #64903
