## Notable Changes

Notable changes of this release include:

* Added the [DISKS plugin](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/system-tables/information-schema/information-schema-tables/information-schema-disks-table), for monitoring the disk space situation.
* [TRIM](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-functions/string-functions/trim), [LTRIM](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-functions/string-functions/ltrim), [RTRIM](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-functions/string-functions/rtrim), [LPAD](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-functions/string-functions/lpad) and [RPAD](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-functions/string-functions/rpad) now return NULL if returning an empty result when [SQL\_MODE=Oracle](https://mariadb.com/docs/release-notes/compatibility-and-differences/sql_modeoracle) - [MDEV-15739](https://jira.mariadb.org/browse/MDEV-15739), [MDEV-15664](https://jira.mariadb.org/browse/MDEV-15664).
* [innodb\_fast\_shutdown](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-usage/storage-engines/innodb/innodb-system-variables) now has a new mode, `3`, which skips the rollback of connected transactions - [MDEV-15832](https://jira.mariadb.org/browse/MDEV-15832)
* The max value of the [max\_prepared\_stmt\_count](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#max_prepared_stmt_count) system variable has been increased from 1048576 to 4294967295
* The [proxy\_protocol\_networks](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#proxy_protocol_networks) variable can now be modified without restarting the server - [MDEV-15501](https://jira.mariadb.org/browse/MDEV-15501)
* The Information Schema is optimized to use much less memory when selecting from [INFORMATION\_SCHEMA.TABLES](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/system-tables/information-schema/information-schema-tables/information-schema-tables-table) or any other table with many [VARCHAR](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/data-types/string-data-types/varchar) or [TEXT](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/data-types/string-data-types/text) columns - [MDEV-14275](https://jira.mariadb.org/browse/MDEV-14275)

* Windows binaries now use high-precision timer when available - [MDEV-15694](https://jira.mariadb.org/browse/MDEV-15694). This makes much less probable for two queries to have the same `CURRENT_TIMESTAMP(6)` value, for example.
* [System versioning](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-structure/temporal-tables/system-versioned-tables) is not allowed for tables in the mysql database - [MDEV-14790](https://jira.mariadb.org/browse/MDEV-14790)

* New Galera system variable, [wsrep\_reject\_queries](https://app.gitbook.com/s/3VYeeVGUV4AMqrA3zwy7/reference/galera-cluster-system-variables#wsrep_reject_queries) for rejecting client connection queries.
* As per the [MariaDB Deprecation Policy](https://gitbook-v2-q3lwp8faq-gitbook.vercel.app/url/mariadb.com/docs/release-notes/community-server/about/platform-deprecation-policy), this will be the last release of [MariaDB 10.3](https://gitbook-v2-q3lwp8faq-gitbook.vercel.app/url/mariadb.com/docs/release-notes/community-server/old-releases/release-notes-mariadb-10-3-series/what-is-mariadb-103) for Debian 7 Wheezy
