Version 2 of SolusVM is a total rebuild of SolusVM. V2 is primarily written in C with a PHP frontend, allowing better stability and more advanced functions and features over version 1.
When will Version 2 be released?
As you know this is not something we can really answer, however we hope to see it hit you guys around April – May 2012.
