Percona is glad to announce the release of Percona Toolkit 2.2.7 on February 24th, 2014 (Downloads are available here and from the Percona Software Repositories). This release is the current GA (Generally Available) stable release in the 2.2 series. This release fixes one security bug. An upgrade is recommended.
Fixed bug 1279502: –version-check behaves like spyware
The configuration for what information Percona Toolkit should retrieve is not hardcoded in the scripts. Instead, it is downloaded from v.percona.com. One of the possible parameters was the name of a binary file to execute with “–version.” This was fixed by removing the ability to execute arbitrary binary files with the version parameter. You can find more information about the benefits of “version check” in the launch post for Percona Toolkit 2.2.
All Percona software is free and open-source. Details of the release can be found in the release notes and the 2.2.7 milestone at Launchpad. Bugs can be reported on the Percona Toolkit launchpad bug tracker.
