Major and minor
AlliedWare Plus uses a numerical release versioning structure, formatted as "a.b.c-d.e". The first number represents the primary software version, with the second and third numbers representing the major software release. The last two numbers represent the minor and maintenance updates release, respectively. Major and minor releases typically introduce new features or product support, while maintenance releases are usually bug fixes. For example, when this article was first written, the current AW+ software version was 5.4.4-2.3.
