MySQL Version Numbers
MySQL 9.7 is the final release line using the previous sequential versioning model. Subsequent MySQL Innovation and LTS releases use calendar versioning in the YY.M format, where YY represents the year and M represents the scheduled release month.
For example, MySQL 26.7 represents the July 2026 release, and MySQL 27.7 represents the July 2027 release. When a release is designated as an LTS release, its YY.M version remains fixed throughout the support lifecycle of that LTS series.
