See the MariaDB versus MySQL page for a high-level overview of the differences between MariaDB and MySQL. For a description of this release see the MariaDB 5.1 overview.
This is a beta release of MariaDB. We believe it to be relatively bug-free, and want to get it out so everyone can try it. Development is ongoing, see MariaDB 5.2 TODO for a list of features that are planned for future MariaDB 5.2 releases.
New features and changes in this version include:
userstatv2 patch from Percona
- This patch enables the gathering of more detailed statistics in MariaDB 5.2.
As part of this patch, several new INFORMATION_SCHEMA
tables (with corresponding new
SHOWcommands) have been added. See: User Statistics for details.
Virtual columns patch (Contribution)
- We've added
PERSISTENTvirtual columns to MariaDB 5.2. See: Virtual columns for details.
Add a mysqlbinlog option to change the used database. MWL#36
- We've added a new
--rewrite-db=nameoption to mysqlbinlog for applying updates to a database with a different name than the original. See: mysqlbinlog for details.
