+----

+When performing a release it is good practice to edit a copy of these notes during the process
+and merge the updated document into the repository following a release. To assist in this process
+a find-and-replace can be performed to update all the version numbers in order. For example
+based on a previous release of 1.4:
+
+- Next development version  : 1.5 -> 1.6
+- Next release version      : 1.4 -> 1.5
+- Previous release version  : 1.3 -> 1.4
+- Release candidate version : RC1 -> RC2   (if applicable)
+
+This allows the included commands to be coped during the release process.

 If you have several GPG keys, you may prefer to use "-u keyId" to select a specific
 key for signing the tag instead of "-s" which select automatically one key
 from the configured e-mail address.
 
 Check the tag GPG signature:
 
-  $ git tag -v RNG_1_4_RC1
+  $ git tag -v commons-rng-1.4-RC1

 as the **last release candidate** tag:
 
-  $ git tag -v RNG_1_4_RCX
+  $ git tag -v commons-rng-1.4-RC1
 
 Check the commit hash then add the release tag.
 Note: The 'rel/' prefix adds the tag to the release section of the tags.
 This cannot be deleted once pushed to the main repository due to restrictions
 on this section of the tag namespace (preventing deletion of official release
 tags).
