Seriously though, you Mojang apologists need to stop being so hostile. All we're trying to do is point out bugs and give constructive criticism for the benefit of the dev team, and you keep jumping down our throats as if we're some sort of horrible troublemaking trolls. When you insult us with ad hominem attacks merely for expressing a dissenting opinion, that's immature. Please, take a step back and look at what you're doing.
Amen to this sentiment. The issue here is that while some bugs were fixed, it seems as many more were created in the process. This update did make for a worse experience for the players on a number of levels, and broke some key parts of the game, which is sort of why the resentment was here.
A great many of these bugs could have been caught by testers, and should have been.
BTW, in terms of the software being in beta, I think we all get that the software is going to be buggy to an extent. Still, when this software "goes gold" and leaves the beta stage of development (previously announced for when that is happening BTW), bugs of this nature should not get even this level of toleration. If there was to be a perpetual "Beta testing" branch where hardcore players would "bless" a release as good to go before it became generally accepted as a stable release, perhaps the criticism would be justified. Beta testing implies that bug reports can and ought to be filed by the "testers", which in this case is the users of the software. That is precisely what is happening here.
Simply put, if you want the stable release, stick with 1.5 as the 1.6 branch is currently very unstable. Those playing this game need to realize that, and the warnings to backup save files are very much justified. Don't trust the software because this particular branch is not ready for prime time yet and in fact inferior to the earlier version of the software.
I've seen this kind of thing happen with other game development companies where they do the public bug testing where key issues simply weren't considered before its release. Money is being paid here, so customers are justifiably upset that they are receiving an inferior product. You can debate if players should pay for updates as a separate issue, and then people would be completely justified for being pissed about this update.
I appreciate that Notch is hard at work (as evidenced by four subsequent rapid patches on the update), but he shouldn't be given a total pass here either. Telling people to shut up and stop complaining about bugs is perhaps the worst thing that can happen right now.
