MySQL version numbers
The version numbering sequence for the RDS for MySQL database engine is either in the form of major.minor.patch.YYYYMMDD or major.minor.patch, for example, 8.0.33.R2.20231201 or 5.7.44. The format used depends on the MySQL engine version. For information about RDS Extended Support version numbering, see Amazon RDS Extended Support version naming.
- major
-
The major version number is both the integer and the first fractional part of the version number, for example, 8.0. A major version upgrade increases the major part of the version number. For example, an upgrade from 5.7.44 to 8.0.33 is a major version upgrade, where 5.7 and 8.0 are the major version numbers.
- minor
-
The minor version number is the third part of the version number, for example, the 33 in 8.0.33.
- patch
-
The patch is the fourth part of the version number, for example, the R2 in 8.0.33.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 8.0.33.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.
