What is the Open Liberty release strategy?

## Continuous fix pack delivery WebSphere Application Server Liberty follows a continuous delivery process. Instead of delivering a large amount of content in a new version, new content is delivered gradually as optional installable features in of each fix pack. Because of the Liberty zero-migration policy, you can update to the latest fix pack and then continue to use your existing configuration and applications, with no unexpected change in behavior. In contrast to WebSphere Application Server traditional, which has different fix packs for each version, Liberty has a single service stream. A Liberty fix pack contains the same content regardless of which product version you purchased. Fix pack 16.0.0.2 is the next Liberty fix pack after 8.5.5.9. ## Fix pack numbering Beginning with fix pack 16.0.0.2, WebSphere Application Server Liberty fix packs use the following numbering scheme: Y.R.M.F where: Y = year, last 2 digits R = release M = modification F = fix pack release during the year For example, fix pack 16.0.0.2 refers to year 2016, release 0, modification 0, and the second fix pack of the year. For the third fix pack of 2018, the fix name would be 18.0.0.3. This numbering change applies only to Liberty. WebSphere Application Server traditional fix packs continue to follow the V.R.M.F numbering scheme, where the letters stand for version, release, modification, and fix pack.
