  • [BETA] The CREATE TABLE statement now supports the SPLIT AT VALUES clause. #1486

  • Improve performance of multi-column primary keys by generating scanspec for range partitioned tables using condition expression. #4033

System improvements

  • Improve tablet splitting #4169, including:
    • Add support for transaction-enabled tables.
    • Add WAL index flush before copying WAL during table splitting.

  • Add backup-related code changes for snapshots #3836, including:
    • Change yb-admin import_snapshot to return an error if there are less new table names than backed up tables. For example, if you rename only two of three tables, an error will be generated.
    • Change yb-admin restore_snapshot and yb-admin list_snapshot to output restoration-id (useful for verifying completed restorations).
  • Support yb-admin import_snapshot renaming only a few tables (but not all), but keeping the specified table name the same as the old table name. #4280

  • Do not return error in output of yb-admin get_is_load_balancer_idle if load balancer is busy. [#3949]

  • Fix yb-ctl failing when passing vmodule in --master_flags . #4234
  • The yugabyte-client package now includes a share folder (containing .sql files) for use by Yugabyte Cloud and other remote client users. #4264

Yugabyte Platform

  • When shrinking a universe, remove nodes in descending index order. #3292
  • Add back up and restore of Yugabyte Platform using script. #4208

  • Fix expected restoration state in the script.

Prior to 2.0, YSQL was still in beta. As a result, 2.0 release includes a backward incompatible file format change for YSQL. This means that if you have an existing cluster running releases older than 2.0 with YSQL enabled, then you will not be able to upgrade to version 2.0+. Export from old cluster and import into a new 2.0+ cluster is needed for using existing data.
