flash引擎-Flixel

Flixel comes in a few different flavors: Master, Beta, and Dev.Master is the most stable, but thusly the oldest code. That giant download button up there is for the Master branch. Beta is newer than Master, but is still being tested by the community. Dev is the least stable, most experimental version of Flixel. Generally, when new features are added to Flixel, they are first added to the Dev branch. When the dust settles, those changes graduate to Beta, and are eventually merged to Master.
