In Percona Server 5.7 super_read_only feature has been replaced with upstream implementation. There are currently two known issues compared to Percona Server 5.6 implementation:
Using primary key with a
BLOBin TokuDB table could lead to a server crash (#916).
Using XA transactions with TokuDB could lead to a server crash (#900).
Percona TokuBackup has not been included in this release.
ALTER TABLEwithout specifying the storage engine (without
enforce_storage_enginewas enabled could lead to unrequested and unexpected storage engine changes. If done for a system table, it would circumvent regular system table storage engine compatibility checks, resulting in crashes or otherwise broken server operation. Bug fixed #1488055.
With Expanded Fast Index Creation enabled, DDL queries involving InnoDB temporary tables would cause later queries on the same tables to produce warnings that their indexes were not found in the index translation table. Bug fixed #1233431.
