Hi, I'm just discovering LE, is it useful to do it every night? Is it a “stable” version ?
And if I make a backup of version 12, can I come back to it without worrying ?
Our nightly builds are very stable, they are just not tested as much as the stable ones.
Make a backup from LE 12, and if something goes wrong with LE 13, you can go back by update folder method.
