RDS version numbers in RDS for MySQL

RDS version numbers use either the major.minor.patch or the major.minor.patch.YYYYMMDD naming scheme. Amazon RDS Extended Support versions use the minor-RDS.YYYYMMDD minor version naming scheme.

An RDS patch version includes important bug fixes added to a minor version after its release. An RDS date version (YYYYMMDD) is a security patch. A security patch doesn't include any fixes that might change the engine's behavior. For information about RDS Extended Support version numbering, see Amazon RDS Extended Support version naming.

You can find out the RDS version number of your RDS for MySQL database with the following SQL query:

mysql> select mysql.rds_version();

For example, querying an RDS for MySQL 8.0.34 database returns the following output:

+---------------------+
| mysql.rds_version() |
+---------------------+
| 8.0.34.R2.20231201  |
+---------------------+
