Announcing Galera Cluster 5.5.46 and 5.6.27 with Galera 3.13

[Philip Stoev]

Codership is pleased to announce the release of Galera Cluster 5.5.46 and
5.6.27 with Galera Replication library 3.13, implementing wsrep API version
25.

Galera Cluster is now available as targeted packages and package
repositories for a number of Linux distributions, including Ubuntu, Debian,
Fedora, CentOS, OpenSUSE and SLES. Obtaining packages using a package
repository removes the need to download individual files and facilitates the
deployment and upgrade of Galera nodes.

This and future releases will be available from
http://www.galeracluster.com, while previous releases remain available on
LaunchPad. The source repositories and bug tracking are now on
http://www.github.com/codership.

New features and notable changes in Galera Cluster and the Galera library:

- security fix for the LogJam issue. The key length used for creating
Diffie-Hellman keys has been increased to 2,048 bits.
- a “compat” package is now provided to allow MySQL-wsrep to be installed
without removing packages such as Postfix which depend on older MySQL
versions
- The MySQL-wsrep packages are now built with OpenSSL rather than YaSSL
(codership/mysql-wsrep#121)
- Galera error messages have been enhanced to contain the current schema
name along with the query (codership/mysql-wsrep#202)
- IB atomic builtins are no longer used when compiling as they may cause the
server to hang (codership/mysql-wsrep#221)
- query cache is now compatible with wsrep_sync_wait
(codership/mysql-wsrep#201)
- a deadlock could occur between the applier thread and an aborted
transaction (codership/mysql-wsrep#184)
- a memory leak could occur when using SHOW STATUS (codership/galera#308)
- DDL was not recorded in InnoDB header, causing InnoDB to recover to an
earlier position (codership/mysql-wsrep#31)
- an assertion could happen with Prepared Statements
(codership/mysql-wsrep#125, codership/mysql-wsrep#126)
- the ‘could not find key from cert index’ warning will no longer be printed
in certain situations (codership/galera#361)
- fix compilation on the latest Debian release (codership/galera#321)
- fix compilation on FreeBSD
- several fixes to the build scripts to support various distros and
architectures (codership/galera#321)
