New Features
Percona Server 5.7.10-1 is not available on RHEL 5 family of Linux distributions and Debian 6 (squeeze).

Complete list of changes between Percona Server 5.6 and 5.7 can be seen in Changed in Percona Server 5.7.
Known issues
MeCab Full-Text Parser Plugin has not been included in this release.

PAM Authentication Plugin currently isn’t working correctly.

Variables innodb_show_verbose_locks and innodb_show_locks_help are not working correctly.

In Percona Server 5.7 super_read_only feature has been replaced with upstream implementation. There are currently two know issues compared to Percona Server 5.6 implementation:
Bug #78963, super_read_only aborts STOP SLAVE if variable relay_log_info_repository is set to TABLE which could lead to a server crash in Debug builds.
Bug #79328, super_read_only set as a server option has no effect.
Using primary key with a BLOB in TokuDB table could lead to a server crash (#916).

Using XA transactions with TokuDB could lead to a server crash (#900).
Bugs Fixed
Running ALTER TABLE without specifying the storage engine (without ENGINE= clause) or OPTIMIZE TABLE when enforce_storage_engine was 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.

Some transaction deadlocks did not increase the INFORMATION_SCHEMA.INNODB_METRICS lock_deadlocks counter. Bug fixed #1466414 (upstream #77399).

Removed excessive locking during the buffer pool resize when checking whether AHI is enabled. Bug fixed #1525215 (upstream #78894).

Removed unnecessary code in InnoDB error monitor thread. Bug fixed #1521564 (upstream #79477)
Other bugs fixed: #371752 (upstream #45379), #1441362 (upstream #56155), #1385062 (upstream #74810), #1519201 (upstream #79391), #1515602, #1506697 (upstream #57552), #1501089 (upstream #75239), #1447527 (upstream #75368), #1384658 (upstream #74619), #1384656 (upstream #74584), and #1192052.
