I am considering downloading Beta Version 2.1 of LyX, I am currently using version 2.0.6 I have Three questions. The first is, how reliable is this beta version? Second, which files should I download If I am already using Version 2.0.6? Lastly, will I be able to use both versions side by side? I got the picture below from here ftp://ftp.lyx.org/pub/lyx/devel/lyx-2.1/lyx-2.1.0beta1.
