MariaDB version numbers
The version numbering sequence for the RDS for MariaDB database engine is either in the form of major.minor.patch.YYYYMMDD or major.minor.patch, for example, 10.11.5.R2.20231201 or 10.4.30. The format used depends on the MariaDB engine version.
- major
-
The major version number is both the integer and the first fractional part of the version number, for example, 10.11. A major version upgrade increases the major part of the version number. For example, an upgrade from 10.5.20 to 10.6.12 is a major version upgrade, where 10.5 and 10.6 are the major version numbers.
- minor
-
The minor version number is the third part of the version number, for example, the 5 in 10.11.5.
- patch
-
The patch is the fourth part of the version number, for example, the R2 in 10.11.5.R2. An RDS patch version includes important bug fixes added to a minor version after its release.
- YYYYMMDD
-
The date is the fifth part of the version number, for example, the 20231201 in 10.11.5.R2.20231201. An RDS date version is a security patch that includes important security fixes added to a minor version after its release. It doesn't include any fixes that might change an engine's behavior.
