+Starting with the 1.0.0 release, HBase is working towards
link:http://semver.org/[Semantic Versioning] for its release versioning. In
summary:
+* APIs available in a patch version will be available in all later patch
versions. However, new APIs may be added which will not be available in earlier
patch versions.
+* Client code written to APIs available in a given patch release can run
unchanged (no recompilation needed) against the new jars of later patch
versions.
+* Client code written to APIs available in a given patch release might not run
against the old jars from an earlier patch version.
+* A patch upgrade is a drop-in replacement. Any change that is not Java binary
compatible would not be allowed.footnote:[See
http://docs.oracle.com/javase/specs/jls/se7/html/jls-13.html.]. Downgrading
versions within patch releases may not be compatible.
