I have reinstalled my main system with this 3.7.x (in development) version, fully 64bit 
The copy of the data was a bit boring, specially since apparently we need to stop using reiserfs, this is a very bad news since it is a very good and fast filesystem but seems like to be entirely abandoned by the kernel developers, not supported at all but even worse: it crashes your entire system (kernel crash) if you simply use it, so will be needed to backup the data and copy it back to the new filesystem system
The good thing is that now the preferred option is btrfs with transparent compression in zstd algorithm, and the overall system is pretty fast, with this filesystem your data takes less space and its also faster to access to it (system faster), my disk has been shrinked in almost half of its size with the same data
Now, the E17 desktop is entirely unusable, E22 is not customized by Elive but E16 which is retro is perfectly usable and customized (not the same features but perfectly usable), I had a little strange feeling using it at the start but now i'm working fluid from it, which is well integrated for Elive and also uses the same hotkeys, its just amazing how light, fast and strongly stable is this underrated desktop. Also it features "sound theme", which you may find funny or annoying but you can disable it. The look is somewhat dark at the moment
New browsers, new drivers, much wider support, bla bla
Finishing to make a few things more ready atm, but as said, E17 is not usable, so bad... Anyways, everything is correctly explained in the system / installation / bla bla
