The entirety of the CHANGELOG for Akeeba Backup for WordPress 8.2.7 is as follows:
Changelog
Critical bugs and important changes
- Could not work with MySQL 5.x and MariaDB 10.x
If it isn't blatantly obvious by its name, a CHANGELOG “is a log or record of all notable changes made to a project”. It describes the important changes made since the previous version.
As it is blatantly obvious by this changelog, there was a bug in Akeeba Backup for WordPress 8.2.6 which broke compatibility with MySQL 5.x and MariaDB 10.x. Since WE VERY OBVIOUSLY STILL SUPPORT MYSQL 5.7 IN AKEEBA BACKUP FOR WORDPRESS 8.X this was considered a critical bug, it was fixed urgently, and triggered the immediate release of 8.2.7.
As it is blatantly obvious, Akeeba Backup for WordPress 8.2.7 is compatible with MySQL 5.7.
As it is blatantly obvious, all versions of Akeeba Backup for WordPress in the 8.x range are compatible with MySQL 5.7, bar from the buggy version 8.2.6 which was immediately retracted and replaced with the fixed version 8.2.7.
