Bugs Fixed
  • With innodb_large_prefix set to 1, Blackhole storage engine was incompatible with InnoDB table definitions, thus adding new indexes would cause replication errors on the slave. Fixed #1126 (upstream #53588).

  • A build error on FreeBSD caused by fixing the bug #255 was present. Bug fixed #2284.
  • Server queries that contained JSON special characters and were logged by audit_log plugin in JSON format caused invalid output due to lack of escaping. Bug fixed #1115.
  • Compilation warnings fixed in sql_planner.cc  module. Bug fixed #3632 (upstream #77637).
  • A memory leak fixed in PFS unit test. Bug fixed #1806 (upstream #89384).
  • A GCC 7 warning fix introduced regression in Percona Server for MySQL 5.6.38-83.0 that lead to a wrong SQL query built to access the remote server when Federated storage engine was used. Bug fixed #1134.
