+This part is intended for committers who are packaging a release.
+
+* Check all your files are checked in
+* Execute "mvn clean test" to be sure all tests are passing
+* Update the version number in pom.xml
+* Update the release date in src/changes/changes.xml
+* Execute "mvn clean test" to be sure all tests are passing
+* Commit the changes
+
+
+* Build and deploy the artifacts 
+
+```
+   mvn -up clean deploy
+```
+
+* Go to [Sonatype staging repositories](https://oss.sonatype.org/index.html#stagingRepositories) and process the deploy
+  - select the repository and close it - wait until the close is processed
