mariadb (1:10.11.2-1) unstable; urgency=medium
MariaDB 10.11.2 was released on February 16th 2023 by the MariaDB Foundation
(https://mariadb.org/mariadb-10-11-2-ga-now-available/). This is the first
release in the 10.11 series to be announced GA (general availability). The
10.11 series has long-term support with commitment from the MariaDB Foundation
(https://mariadb.org/about/#maintenance-policy) to publish maintenance
versions with fixes to software defects and security vulnerabilities until
February 2028.
The previous major releases (10.7, 10.8, 10.9, 10.10) were not long-terms
supported versions and thus not imported to Debian. To learn what is new in
10.11 it is recommended to read all the release notes:
* https://mariadb.com/kb/en/changes-improvements-in-mariadb-1011/
* https://mariadb.com/kb/en/changes-improvements-in-mariadb-1010/
* https://mariadb.com/kb/en/changes-improvements-in-mariadb-109/
* https://mariadb.com/kb/en/changes-improvements-in-mariadb-108/
* https://mariadb.com/kb/en/changes-improvements-in-mariadb-107/
Notable new features:
- New datatypes UUID and INET4
- New functions SFORMAT (text formatting), NATURAL_SORT_KEY, RANDOM_BYTES and
several related to JSON
- New keyword AUTO in system versioned tables for partitioning
(https://mariadb.com/kb/en/system-versioned-tables/#automatically-creating-partitions)
- Unicode Collation Algorithm (UCA) upgrade to 14.0.0
- New privileges 'READ ONLY ADMIN' and 'GRANT TO PUBLIC'
(https://mariadb.org/grant-to-public-in-mariadb/)
- password_reuse_check plugin (part of mariadb-server package)
- Hashicorp Key Management Plugin for implementing encryption using keys
stored in the Hashicorp Vault KMS (mariadb-plugin-hashicorp-key-management
package)
Important packaging change: Compression libraries have been split into
separate packages named mariadb-provider-plugin-(bzip2/lz4/lzma/lzo/snappy).
If a non-zlib compression algorithm was used in InnoDB or Mroonga before
upgrading to 10.11, those tables will be unreadable until the appropriate
compression library is installed.
Things to consider when upgrading from 10.6 to 10.11 are listed on the page
https://mariadb.com/kb/en/upgrading-from-mariadb-10-6-to-mariadb-10-11/.
New server variables in 10.11 (compared to 10.6):
- binlog-alter-two-phase: When set, split ALTER at binary logging into 2
statements: START ALTER and COMMIT/ROLLBACK ALTER. Defaults to 'FALSE'.
- innodb-log-file-buffering: Whether the file system cache for ib_logfile0 is
enabled
- optimizer-extra-pruning-depth: If the optimizer needs to enumerate join
prefix of this size or larger, then it will try aggressively prune away the
search space.
- log-slow-min-examined-row-limit: Don't write queries to slow log that
examine fewer rows than that
- log-slow-query: Log slow queries to a table or log file. Defaults logging to
a file 'hostname'-slow.log or a table mysql.slow_log if --log-output=TABLE
is used. Must be enabled to activate other slow log options.
- log-slow-query-file: Log slow queries to given log file. Defaults logging to
'hostname'-slow.log. Must be enabled to activate other slow log options
- log-slow-query-time: Log all queries that have taken more than
log_slow_query_time seconds to execute to the slow query log file. The
argument will be treated as a decimal value with microsecond precision
- slave-max-statement-time: A query that has taken more than
slave_max_statement_time seconds to run on the slave will be aborted. The
argument will be treated as a decimal value with microsecond precision. A
value of 0 (default) means no timeout
- system-versioning-insert-history: Allows direct inserts into ROW_START and
ROW_END columns if secure_timestamp allows changing @@timestamp
- wsrep-allowlist: Allowed IP addresses split by comma delimiter
- wsrep-status-file: wsrep status output filename
Changed behavior in server variables in 10.11 (compared to 10.6):
- explicit-defaults-for-timestamp: enabled by default
- optimizer-prune-level: defaults to 2 (instead of 1)
- old-mode: new options IGNORE_INDEX_ONLY_FOR_JOIN and COMPAT_5_1_CHECKSUM
- wsrep-mode: new option BF_ABORT_MARIABACKUP
- read-only: changing value requires 'READ ONLY ADMIN' privilege
One of the most important performance related server variables
'innodb_log_file_size' is now dynamic so it can be changed without having to
restart the server.
Removed in 10.11 (compared to 10.6):
- innodb-log-write-ahead-size: the physical block size of the underlying
storage is instead detected and used
- wsrep-replicate-myisam: use wsrep_mode instead
- wsrep-strict-ddl: use wsrep_mode instead
Deprecated server variables:
- innodb_change_buffering
- innodb-buffer-pool-chunk-size: defaults to 0 (instead of 134217728) in
server variables because the server automatically sizes it
- keep_files_on_create: orphan files are now deleted automatically, so this
setting should never be needed
Note also that the MariaDB client settings have changed to now use SSL/TLS
by default.

mariadb (1:10.11.1-1) unstable; urgency=medium
Version suffixed packages (e.g. mariadb-server-10.6) have now been deprecated
as it made maintenance complicated and there was no known use cases or users
of the naming scheme, as multiple different major version MariaDB server
packages could not be co-installed anyway and source or the 'mariadb-server'
and 'mariadb-client' packages is easiest controlled by repositories and
package versioning, not versions in package *names*.

mariadb-10.5 (1:10.5.5-1) unstable; urgency=medium
The latest version 10.5 of the MariaDB Server came out in June 2020 and is
guaranteed to have security releases at least until summer 2025.
For more information on what is new in MariaDB 10.5 check out:
https://speakerdeck.com/ottok/debconf-2020-whats-new-in-mariadb-server-10-dot-5-and-galera-4
or video from https://peertube.debian.social/videos/watch/bb80cf53-d9ba-4ed9-b472-a21238fb67f5.
Quick summary:
- Service name is now 'mariadb', e.g. /etc/init.d/mariadb and systemctl mariadb
- The main server binary is now running as 'mariadbd' instead of old 'mysqld'
- Many commands are now mariadb-* instead of old mysql*, but old names
continue to work as symlinks
- Referencing the /etc/mysql/debian.cnf file is not advised anymore. It will
be deprecated in a future Debian release and has been obsolete anyway for
several years now since MariaDB in Debian introduced Unix socket
authentication for the root account in 2015.
MariaDB 10.5 has been tested to be backwards compatible with all previous
versions of MariaDB and all previous versions of MySQL up until version 5.7.
Note that MySQL 8.0 introduces significant backwards incompatible changes
compared to MySQL 5.7, and thus in-place binary upgrades from MySQL 8.0 to
MariaDB 10.5 are not possible, but sysadmins need to upgrade by exporting and
importing SQL dumps of their databases.
If you encounter any bugs, please make sure your bug report is of highest
standards so we can quickly reproduce and fix the issue. Even better if you
find the solution yourself, and can submit it as a Merge Request at
https://salsa.debian.org/mariadb-team/mariadb-10.5/
If you appreciate the Debian packaging work done, please star us on Salsa!

mariadb-10.1 (10.1.20-1) unstable; urgency=low
MariaDB is now the default MySQL variant in Debian, at version 10.1. The
Stretch release introduces a new mechanism for switching the default
variant, using metapackages created from the 'mysql-defaults' source
package. For example, installing the metapackage 'default-mysql-server' will
install 'mariadb-server-10.1'. Users who had 'mysql-server-5.5' or
'mysql-server-5.6' will have it removed and replaced by the MariaDB
equivalent. Similarly, installing 'default-mysql-client' will install
'mariadb-client-10.1'.
Note that the database binary data file formats are not backwards
compatible, so once you have upgraded to MariaDB 10.1 you will not be able
to switch back to any previous version of MariaDB or MySQL unless you have a
proper database dump. Therefore, before upgrading, please make backups of
all important databases with an appropriate tool such as 'mysqldump'.
The 'virtual-mysql-*' and 'default-mysql-*' packages will continue to exist.
MySQL continues to be maintained in Debian, in the unstable release. See the
page https://wiki.debian.org/Teams/MySQL more information about the
mysql-related software available in Debian.
