Two releases ago the RC was better than 1.19. Now I red map out on every computer I have access to. It is total junk. Total complete junk. Did I tell you that it is complete junk? Then came the "required" release that crashed linux. That one did not work on my computer either. I don't know much about software development, but I do know that software that does not run is not worthy of release candidate status.
Every release of the client has gotten worse and worse and worse and worse. I'm still on Nicholaz, I advise all mac users to go to and stay on Nicholaz. (Here are the links to get 18.104.22.168 and then the mac patch.)
I have to say it: who ever is managing client development and quality assurance at LL hits 10 on the bozometer. These are not "release candidates" but furball builds coughed up from the innards of a yak with a keg of Corona as a build methodology. Fire this person. Fire which ever Linden decided that pissing of Nicholaz was good for lulz.
[I've updated the side links with Coolview as an open source client. And with Barney's coolview page for Mac. These are working on the machines I can test them on, will report more later. 768 leashing needs to be fixed next.]
This isn't software, it's griefing the user base.
