I personally liked the idea of restricting access to login accounts. But, Dimi is right, we need to be able to link to bug reports from other pages. So, the restricted access is now disabled in bugzilla.
Also, there has been reports of some bugs loosing descriptions. Since the upgrade process is not reversible there is not much I can do about it. So this is a call for everyone to go through and check the bugs you submitted. If there is no desc, please re-enter one in the bug report. Don't submit them to me, I'll just ignore requests to fix individual bugs.
Also, don't ask me to add anything to the bugzilla code. If you want a feature in bugzilla, submit it to the main bugzilla page at: http://www.bugzilla.org/ If they include your feature I will put it in when the next stable build of bugzilla comes out. The most I will do is customize the look and feel via the new bugzilla template system. Any other changes I do always get lost when I upgrade to newer bugzilla builds.
