Dear Community,

Starting with this release, we introduce a new release model for Percona Server. From now on, we will have both Stable and Release Candidate releases. Release Candidates will introduce new features not yet available in Stable releases.

Along with new features, our new 5.1.49-12.0 RC contains a couple of patches from the Facebook-MySQL tree - https://launchpad.net/mysqlatfacebook . Of particular note is better integration with FlashCache.

We also introduce the very interesting new feature called ”Permanent InnoDB Buffer Pool”  (sponsored by a Well Known Social Network site). It allows you to keep the InnoDB buffer pool in memory between restarts of MySQL servers.
This can result in a significant decrease in warmup time after MySQL restarts.

Starting with this release, we will also provide special …

MySQL Proxy 0.8.0 has been released at http://dev.mysql.com/downloads/mysql-proxy/

While it took a while to get it out, it contains a lot of good stuff and will make a few more things possible for the future. First of all, it is the first release with a threaded network-backend allowing to use plenty of CPUs.

The other big infrastructure change is mostly for developers: out-of-tree plugins can now be written. Now you can write plugins for the MySQL Proxy against a installed MySQL Proxy. No need to have the MySQL Proxy's source code around.

ChangeLog

• added a threaded event handling layer
• added support to change the auth-response on the way to the backend
• added timing infrastruture
• added out-of-tree plugins builds and pkg-config support
• fixed handling of broken length encoded data in …

If you have seen the following error on the Perf Report tab “Message: SimpleXMLElement::__construct()…” – it has been fixed in revision 281. This only affects alerts 11 and 12 so you might not run into it immediately. The solution is to either remove lines “586, 590, 639, 650″ from the bin/kontroll-reporter-5.0.x_linux-x86-2.0.1.pl file, or to run [...]

OverviewWhat's this new …

Some good changes in this release as usual. There have been some more additions to the analytics, some speed up of the UI and login process, and some long awaited fixed for form Vtypes. In addition to those items, I’m a particular fan of the new Analytics Export tab that lets you grab all of [...]
