I discovered today there is a 4.0.308.1 version of PDF Tools 4 SDK (June 3 2014).
I'm using your tool in a software of mine, it's a "old" 2013 version.
Where can I find a changelog? I'd like to upgrade my next projects to this new version, but I need to be sure there will be no problem. I mean: if this new version is faster or provides new functions it's ok, but if some functions are changed or used in a different way it would be a disaster
Thanks,
Luca
