Connection Redirection

InnoDB

Replication

  • Add keywords "SQL_BEFORE_GTIDS" and "SQL_AFTER_GTIDS" for START SLAVE UNTIL (MDEV-27247). SQL_BEFORE_GTIDS stops the replica when it sees gtids of the option's argument list, without executing them.

SSL/TLS

Data Types

  • INET4 data types can now be cast into INET6 types (MDEV-31626)
  • This means, INET4 values can be compared with INET6 values and can be inserted into INET6 columns, the server can automatically convert INET4 value into INET6 as needed.

Functions

  • Key derivation function KDF for generating good encryption keys for AES_ENCRYPT (MDEV-31474)

Date and Time

  • DATE_FORMAT function can now print the current time zone abbreviation and current time zone offset from UTC with %Z and %z format specifiers. (MDEV-31684)

Optimizer

Privileges

  • Add a new database-level privilege, SHOW CREATE ROUTINE that allows to see the routine definition even if the user isn't the routine owner (MDEV-29167)

Processlist

  • Added a SENT_ROWS column to the Information Schema PROCESSLIST table, as well as extended the display size for the columns in processlist to ensure that most results will fit in display (MDEV-3953)

Application-Time Periods

OLD_MODE

  • Setting a non-default old_mode value will now always issue a deprecation warning (MDEV-31811)

Mariabackup

Spider

  • The Spider storage engine now supports table options instead of having to encode them in COMMENT/CONNECTION strings. When any table option is specified, Spider will ignore COMMENT/CONNECTION strings at the same table/partition/subpartition. A new variable spider_ignore_comments is introduced to ignore them globally at all levels (table/partition/subpartition). Another variable, spider_suppress_comment_ignored_warning, is introduced to suppress warnings when Spider ignores COMMENT/CONNECTION strings. (MDEV-28856)
