Percona announces the release of Percona Server for MySQL 5.5.59-38.11 on January 30, 2018. Based on MySQL 5.5.59, including all the bug fixes in it, Percona Server for MySQL 5.5.59-38.11 is now the current stable release in the 5.5 series.
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 GCC 7 warning fix introduced introduced regression in Percona Server 5.5.58-38.10 that lead to a wrong SQL query built to access the remote server when Federated storage engine was used. Bug fixed #1134.
Percona Server 5.5 embedded server builds were broken. Bug fixed #2893.
Percona Server now uses TraviCI for additional tests. Bug fixed #3777.
Other bugs fixed: #257 and #2415.
