Notable Changes

Notable changes of this release include:

Syntax

Privileges

  • Split SUPER privilege to smaller privileges (MDEV-21743). New privileges were added so that more fine grained tuning of what each user can do can be applied:
    • SET USER
    • FEDERATED ADMIN
    • CONNECTION ADMIN
    • READ_ONLY ADMIN
    • BINLOG ADMIN
    • BINLOG REPLAY
    • REPLICATION SLAVE ADMIN
    • REPLICATION MASTER ADMIN
  • In order to help the server understand which version a privilege record was written by, the mysql.global_priv.priv field contains a new JSON field, version_id (MDEV-21704)
  • SHOW PRIVILEGES now correctly lists the Delete history privilege, rather than displaying it as Delete versioning rows. (MDEV-20382)
