I "think" the changelog thread http://www.forum.cncdrive.com/viewforum.php?f=12 is only updated for the official / final public release and not for the test UCCNC versions which are released in this thread http://www.forum.cncdrive.com/viewtopic.php?f=2&t=240 {and are accepted to maybe have unknown bugs in them.... that is why they are test releases, occassionally they are withdrawn when something major is found and users are asked to use the previous test release instead}
Or at least that was the way the changlog was apprearing to work when 037 was the last official current {non-beta} release.

I see its now been updated to 047 and the changelog has not been updated... :/ as the changelog thread is locked it may be worthwhile pointing users to the test release thread for the changelog then....
