Bugs Fixed:

• Percona Servercouldn’t be built withBison3.0. Bug fixed#1262439, upstream#71250.
• Backported the upstream fix for overflow which would caused replication SQL thread to fail to execute events. Bug fixed#1070255(upstream#67352).
• Percona Serverdebug packages were not built for the previous releases. Bug fixed#1298352.
• Queries that no longer exceedlong_query_timewere written to the slow query log if they matched the previouslong_query_timevalue whenslow_query_log_use_global_controlvariable was set toall. Bug fixed#1016991.
• When writing audit plugins it was not possible to get notifications for general-log events without enabling the general-log. Bug fixed#1182535(upstream#60782).
• mysqld_safedid not correctly parseflush_cachesandnuma_interleaveoptions. Bug fixed#1231110.
• Thread Poolwould handle a new client connection without notifying Audit Plugin. Bug fixed#1282008.
• Fixed a performance issue in extending tablespaces if running under fusionIO withatomic writesenabled. Bug fixed#1286114(Jan Lindström).
• Previous implementation of thelog_slow_rate_typeset to query withlog_slow_rate_limitfeature would log every nth query deterministically instead of each query having a 1/n probability to get logged. Fixed by randomly selecting the queries to be logged instead of logging every nth query. Bug fixed#1287650.
• Percona Serversource files were referencingMaatkitinstead ofPercona Toolkit. Bug fixed#1174779.
• Maximum allowed value forlog_slow_rate_limitwasULONG_MAX(ie. eitheror, depending on the platform). As it was unreasonable to configure the slow log for every four billionth session/query, new maximum allowed value is set to. Bug fixed#1290714.
