is going to let go thier traditional release model for a new one.
As it is stated in an announcement. This is done to have more frequent and timely GA releases of the MySQL server, which allow a faster integration of new features and complex changes.
If you are just interested in maintaining a stable server you will not be affected. Because this will just be for development versions.
The basic principles of this model are:
- The trunk is always at least in beta quality.
- A milestone starts in beta quality (never in alpha) with a merge between the trunk and a stage tree;
- Milestone releases, with RC quality, released every three to six months.
- Integration windows between milestones allow the insertion of new features from staging trees
- GA releases happen every 12 to 18 months;
- There are not more than two releases in active support.
Which should look like this:
