To grab a copy of openFrameworks for your platform, check the download page on the main site. The master branch of this repository corresponds to the most recent release, with a few differences:

1. The release includes a simple openFrameworks project generator.
2. This GitHub repository contains code and libs for all the platforms, but the releases are done on a per-platform basis.
3. This GitHub repository has no project files for the different examples. They are generated automatically for each release using a tool in apps/devApps/projectGenerator/.

If you want to work with the openFrameworks GitHub repository, you should use the project generator to create project files for all the code in examples/.

For per-platform readmes, see readme.osx, readme.linux, etc.

openFrameworks uses Semantic Versioning, although strict adherence will only come into effect at version 1.0.0.
