Otto, there is no need to be rude. I'm very sorry if you feel offended.
I'm not offended at all, and I'm not intending to "be rude". Remember, text is a poor medium of conveying emotion. I'm trying to be straightforward and realistic. Don't confuse "bluntness" for "rudeness".
The truth is this:
1. The upgrade locked me out of my own installation, through no action of my own. I am positive of this.
2. The recover password link did not work. It sent an invalid key, upon repeated attempts.
While I have no problem believing #2 (that's where the "bug" is), the fact is that #1 is simply not the case. It's far more easy for me to believe that you forgot or mistyped your password than it is for me to believe that your password hash changed in some arbitrary way without your being aware of it. Sorry, not trying to be rude, just being blunt about it.
Here is a link to the bug tracker for this particular issue, if you'd like to follow it further:
I'd say, though, that an upgrade's rendering an installation basically unusable on a standard, unhacked, previously stable setup is more than just a bug or glitch.
It depends on what exactly you're talking about here. #2 is a known bug with a known and (partially) working fix for it. #1 is not a bug in the slightest, because the simple fact is that it worked without issues for me, on dozens of sites, and for almost everybody else. If there was an actual real bug where your password no longer worked, then everybody would be bitching about it. They're not. QED.
