MySQL 5.7.36 includes the following InnoDB changes:
Bug#32771259: PAGE COMPRESSION OF INNODB TABLE IS IGNORED DURING RECOVERY PROCESS AND MIGHT NEVER SUCCESS WITH ENOSPC CRASH NEAR TO DISK-FULL
In MariaDB recovery, we recover the tablespace attributes based on the first page of the file, or the log written for them. This code was last touched in
MDEV-23199 and in the 10.6 optimization MDEV-24626. The InnoDB redo log recovery does not depend on any data dictionary.
BUG#33181859: Followup for Bug 32800020 - the deadlocking continues
Thanks to us fixing
MDEV-12289 before the 10.2 GA release, MariaDB never broke the undo log compatibility with MySQL 5.6 or older MariaDB releases. All 128 rollback segments in the persistent data files continue to work just fine.
