+## Commit Message
+
+The Apache Cassandra project has a commit message precendence like
+```
+<One sentence description, usually Jira title or CHANGES.txt summary>
+
+ patch by <Authors>; reviewed by <Reviewers> for CASSANDRA-#####
+```
+
+The 'patch by …; reviewed by' line is important.  It permits our review-than-commit procedure, allowing commits from non-git-branch patches.  It is also parsed to build the project contribulyse statistics found [here](https://nightlies.apache.org/cassandra/devbranch/misc/contribulyze/html/).

 ## Beyond The Checklist
 
 In addition to stating the hard requirements, there are a bunch of things that we consider when assessing changes to the library. These soft requirements are helpful pointers of how to get a patch landed quicker and with less fuss.

 ### Supported Features
 
 gocql is a low level wire driver for Cassandra CQL. By and large, we would like to keep the functional scope of the library as narrow as possible. We think that gocql should be tight and focused, and we will be naturally skeptical of things that could just as easily be implemented in a higher layer. Inevitably you will come across something that could be implemented in a higher layer, save for a minor change to the core API. In this instance, please strike up a conversation in the Cassandra community. Chances are we will understand what you are trying to achieve and will try to accommodate this in a maintainable way.

-## Officially Supported Server Versions
-
-Currently, the officially supported versions of the Cassandra server include:
-
-* 1.2.18
-* 2.0.9
-
-Chances are that gocql will work with many other versions. If you would like us to support a particular version of Cassandra, please start a conversation about what version you'd like us to consider. We are more likely to accept a new version if you help out by extending the regression suite to cover the new version to be supported.
