For download coordinates and archetype usage, see the project's README.md document.
At the time of this writing and the release of the aforementioned versions, there are no significant differences between the source files of the master (5.3.x), 5.2.x, and 5.1.x branches. The main purpose of having three branches is for the convenience of testing with three different versions of the Spring Framework.
