This beta release is great news, I am eager to test it :)
Thank you Gidgreen for this hard work!
If I may say so, for accuracy, the "change log" your are pointing to is rather a diff of the files modification. The changelog would rather be the info on the download page http://www.question2answer.org/versions.php
You could actually *normally* issue an accurate changelog using "git log" command (provided that you have cloned the repo). Just like mentioned here for instance https://coderwall.com/p/5cv5lg :you would just need to replace version tags by commit hash since Q2A repo hasn't got actual tags on the repo.
However I say *normally*, because this assume a "standard" git practice of one commit for each and every change / fix, which is not exactly the case here (no offense here, just facts ;))
