Version 2.2.2-201404240550 is a maintenance release.
It was issued to correct the following bugs:
In addition, the following changes were applied to the development environment:
- in preparation for Eclipse 4.4 Luna, the JDK was switched to version 7
- the version of the maven plug-in used for builds (tycho) was updated to 0.20.0.
Except building slightly faster, these changes should have no functional impact on the plug-ins.
Finally, after being marked as ‘end-of-life’ in the past 6 months, the venerable 0.5.5.x plug-in was retired from the update site; it can still be downloaded as an archive from the SourceForge Files section, but is not recommended for new projects.
