It's fine as long as you keep consistent naming. Calling 3.7 version 4 is dumb, if you're going to call it 4 then bump up the version number, if you're not going to bump up the version number until later then stop calling it 4.
I moved to Seattle with my dog, from Indiana.
She's anything but a city dog, and I think the next time I drive home, she'll be coming with me; I'll give her to a friend or my sister.
As dog-friendly as Seattle is, there are definitely dogs that can't do the city.
I don't think I'll ever get to this point, but I'm slowly working my way up. Sold a few computers, excessive speakers, and more a few weeks ago to finish paying off my collegiate credit card debt.
It's unbelievably liberating.
