The upcoming platform update is scheduled for Wednesday, May 28, 2014.
The star of this update is PHP. We’re expanding our platform to support testing and deployment of PHP projects. As the first step, three versions will be available on the platform out of the box: 5.3.28, 5.4.28 and 5.5.12. We are looking forward to sharing more news regarding PHP with you soon.
A full list of changes is available in the platform changelog.
