Release Engineering - logstash	content_right

logstash rel-eng.

The version patterns for logstash are x.y.z

• In the same x.y release, no backwards-incompatible changes will be made.
• Between x.y.z and x.y.(z+1), deprecations are allowed but should be functional through the next release.
• Any backwards-incompatible changes should be well-documented and, if possible, should include tools to help in migrating.
• It is OK to add features, plugins, etc, in minor releases as long as they do not break existing functionality.

I do not suspect the 'x' (currently 1) will change frequently. It should only change if there are major, backwards-incompatible changes made to logstash, and I'm trying to not make those changes, so logstash should forever be at 1.y,z, right? ;)
