A Guide to Software Revisions
Once you start playing with software you quickly become aware that each
software package has a revision code attached to it. It is obvious that
this revision code gives the sequence of changes to the product, but in
reality there's substantially more information available through the rev
code than that. This article provides a guide for interpreting the meaning
of the revision codes and what they actually signify.
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.
We fixed all the killer bugs ...
Uh, we introduced a few new bugs fixing the killer bugs and so we had
to fix them, too.
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.
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
Uh, sorry, one slipped through. One lousy typo error and you won't
believe how much trouble it caused!
Some anal-retentive pain in the ass found a deep-seated bug that's been
there since 1.0 and has been raising hell until we fixed it.
Hey, we finally think we've got it right! Most of the customers are
really happy with this.
Of course we did break a few little things.
More features. It's doubled in size now, by the way, and you'll need
to get memory and a faster processor ...
Just one or two bugs this time. Honest.
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.
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.
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 them.
