Understanding software version numbers
1.0: Also known as "one point uh-oh", or "barely out of beta". We had to release because the lab guys had
reached a point of exhaustion and the marketing guys were in a cold sweat of terror.
1.1: We fixed all the killer bugs ...
1.2: Uh, we introduced a few new bugs fixing the killer bugs and so we had to fix them, too.
2.0: We did the product we really wanted to do to begin with. Mind you, it's really not what the
customer needs yet, but we're working on it.
2.1: Well, not surprisingly, we broke some things in making major changes so we had to fix them. But we did
a really good job of testing this time, so we don't
think we introduced any new bugs while we were fixing these bugs.
2.2: Uh, sorry, one slipped through. One lousy typo error and you won't believe how much trouble it
caused!
2.3: Some jerk found a deep-seated bug that's been there since 1.0 and wouldn't stop nagging until we
fixed it!!
3.0: Hey, we finally think we've got it right! Most of the customers are really happy with this.
3.1: Of course, we did break a few little things.
4.0: More features. It's doubled in size now, by the way, and you'll need to get more memory and a faster
processor...
