Amazon RDS Extended Support version naming

Amazon RDS will release new minor versions with fixes and CVE patches for engines on RDS Extended Support. The names of these minor releases will be in the form major.minor-RDS.YYYYMMDD.patch.YYYYMMDD, for example, 5.7.44-RDS.20240208.R2.20240210 (for RDS for MySQL) or 11.22-RDS.20240208.R2.20240210 (for RDS for PostgreSQL).

major

For MySQL, 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.

For PostgreSQL, the major version number is the integer, for example, 11.

minor-RDS.YYYYMMDD

For MySQL, the minor version number is the third part of the version number, for example, the 44-RDS.20240208 in 5.7.44-RDS.20240208.

For PostgeSQL, the minor version number is the second part of version number, for example, the 22-RDS.20240208in 11.22-RDS.20240208.
