Introduce guidelines for standardized milestones

[jrgriffiniii]

Currently there are inconsistent and varied milestones for each core component. There should be recommended guidelines for the milestones for each of these GitHub Projects.

Evaluating branch naming practices which have been followed by other practices, there seems to be the following pattern which has emerged:

- 1.x-stable
- 2.x-stable
- 2.1-stable
- 3.0.0-release

What I shall propose is that, for cases such as one with three major releases:

• 3.0.0
• 2.2.1
• 1.1.2

...that there be the following branches:

• 1.1-stable
• 2.2-stable
• 3.0-stable

Please note that minor releases should ensure that only backwards-compatible changes are introduced:

MINOR version when you add functionality in a backwards compatible manner, and

Hence, 1.0-stable would be released for the initial 1.0.0 version, and then track each successive change until 1.1.0 is released. Once 1.1.0 is released, the branch 1.0-stable should be deleted, and 1.1-stable should be created. Henceforth, 1.1-stable should contain all of the changes for the next patch release.

Milestones should then follow this pattern, with each milestone tracking defined releases:

• 1.1.2 (Closed Milestone)
• 1.1.3 (Open Milestone)
• 2.2.1 (Closed Milestone)
• 2.2.2 (Open Milestone)
