+Rules for major, minor and point releases
+=========================================
+
+It should always be safe to upgrade a system to the latest point release with matching
+major and minor version. If upgrading to a new major or minor version, users should always
+use the latest available point release. It is important to observe the following rules:
+
+1. Sequence number increases on a gold release are for build errors and regressions only.
+   A new sequence release should be considered as rendering earlier sequence releases invalid
+   and unsupported.
+2. NEVER include new functionality in point releases - only bug fixes
+3. If a bug fix introduces incompatibilities that might break existing ECL code, or
+   require it to be recompiled, it should be held until the next minor release.
+4. Any bug fix that is included in a gold release for a give major.minor version must
+   also be available (if relevant) in a gold release of all later released major.minor versions.
