We just released Valentina 5.7.5 update today. If you got Omegabundle for Xojo 2014 (which ends Monday, March 9 2015), or you purchased within the last 12 months this is a free update.
There are some improvements to Valentina Kernel and Valentina Server, but perhaps more specifically interesting is that there were some improvements to the example projects based on your feedback. The blog announcement with details is here.
I don’t want to assault you with too many links - for more information you can also visit the Paradigma Software website.
