Software Revision Guide

By now you have undoubtedly noticed that all software packages have version numbers. In theory each version represents improvements to the product, but many people have found that the version numbers tend to follow a general pattern. Use this guide to decipher the hidden meaning of version numbers. Also, do not be fooled. Using the year as the version number is a clever ploy, but it does not eliminate the fact that 4.0 follows 3.1.
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. We're praying that you'll find it more functional than, say, a computer virus and that its operation has some resemblance to that specified in the marketing copy.
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 anal-retentive pain in the rear found a deep-seated bug that's been there since 1.0 and has been raising heck 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 memory and a faster processor ...
4.1:
Just one or two bugs this time. Honest.
5.0:
We really need to go on to a new product but we have an installed base out there to protect. We're cutting the staffing after this.
6.0:
We had to fix a few things we broke in 5.0. Not very many, but it's been so long since we looked at this thing we might as well call it a major upgrade. Oh, yeah, we added a few flashy cosmetic features so we could justify the major upgrade number.
6.1:
Since I'm leaving the company and I'm the last guy left in the lab who works on the product, I wanted to make sure that all the changes I've made are incorporated before I go. I added some cute demos, too, since I was getting pretty bored back here in my dark little corner (I kept complaining about the lighting but they wouldn't do anything). They're talking about obsolescence planning but they'll try to keep selling it for as long as there's a buck or two to be made. I'm leaving the bits in as good a shape as I can in case somebody has to tweak them, but it'll be sheer luck if no one loses the source code.
