Announcing Percona Server 5.6 Alpha

We are very happy to announce our first alpha of Percona Server 5.6. Based on MySQL 5.6.5 and all the improvements contained within, this is the first step towards a full Percona Server 5.6 release.

Binaries are available to download from our downloads site here:

We will post binaries to our EXPERIMENTAL repositories later, we’re undergoing final testing to ensure that it won’t cause problems for those running Percona Server < 5.6 from EXPERIMENTAL.

Percona Server 5.6.5-alpha60.0 does not contain all the features of Percona Server 5.5. We are going to “release early, release often” as we add features from Percona Server 5.5. As such, our documentation will not be complete for a little while yet and these release notes are currently the best source of information – please bear with us.

Features included:

  • Bug fix for Bug #933969
  • ignore-create-error option to mysqldump
  • control online alter index
  • SHOW TEMP patch

We have decided to not port the following feature:

  • optimizer_fix variable

We welcome feedback on this release, and encourage people to try it out. It should go without saying that this ALPHA is NOT intended for production use.
