[x264-devel] What can I do if I want to checkout a specified build version

[Emily Bowman]

API versioning is hard and this method is common in open source media
products. A simple check against the library version tells you if you know
how to handle it, so it's an early way to know you can't link this one.

x264 and its API are not the same, though, so I wouldn't call API versions
x264 versions. The library version encompases features and adjustments and
general stability, and usually leaps a couple of API versions. The API
version says nothing other than the library won't crash if you know this
version, but might if you don't.

Stable branch gets master branch commits after enough testing. Right now
there are no differences; most patches lately have been quite minor. It's
been a long time since a really experimental update.
