Rouge change log can be found here https://github.com/AftermathFreelancer/F...es/tag/1.3. I know I've forgotten some stuff from there. You can browse the commit history if you really want to know in depth what changed beyond that.
Note: There may be bugs. This is me we're talking about.
It's been brought to my attention some people are having SSL errors. This is because the old version used to run on http and the auto updater doesn't know how to automatically switch to use SSL. If that's the case, you'll just need to redownload it manually from github directly. I just updated it to compensate for this.
