Percona XtraDB Cluster 5.7.26-31.37

Percona is glad to announce the release of Percona XtraDB Cluster 5.7.26-31.37 on June 26, 2019. Binaries are available from the downloads section or from our software repositories.

Percona XtraDB Cluster 5.7.26-31.37 is now the current release, based on the following:

Bugs Fixed

  • #2480: In some cases, Percona XtraDB Cluster could not replicate CURRENT_USER() used in the ALTER statement. USER() and CURRENT_USER() are no longer allowed in any ALTER statement since they fail when replicated.

  • #2487: The case when a DDL or DML action was in progress from one client and the provider was updated from another client could result in a race condition.

  • #2490: Percona XtraDB Cluster could crash when binlog_space_limit was set to a value other than zero during wsrep_recover mode.

  • #2491: SST could fail if the donor had encrypted undo logs.

  • #2537: Nodes could crash after an attempt to set a password using mysqladmin

  • #2497: The user can set the preferred donor by setting the wsrep_sst_donor variable. An IP address is not valid as the value of this variable. If the user still used an IP address, an error message was produced that did not provide sufficient information. The error message has been improved to suggest that the user check the value of the wsrep_sst_donor for an IP address.

Other bugs fixed: #2276, #2292, #2476, #2560
