Robert Scholte commented on MRELEASE-431:
-----------------------------------------

There are at least two options:
- through Plexus Components ( example is [Maven Compiler 
Plugin|http://maven.apache.org/plugins/maven-compiler-plugin/xref/org/apache/maven/plugin/compiler/AbstractCompilerMojo.html#420]
 where you can choose a compiler by its id. Implementations are marked as a 
Component and can be chosen by the hint.
- through Plexus Configuration. I couldn't find a good example, but it should 
be something like this:
{code:xml}
  <configuration>
    <versionPolicyManager 
implementation="com.acme.custom.MyVersionPolicyManager">
    </versionPolicyManager>
  </configuration>
{code}
The advantage of the latter is that it is very straightforward if you want to 
use additional fields/setters on your VersionPolicyManager. For that reason 
this would be my choice right now.

>             Project: Maven 2.x Release Plugin
>          Issue Type: New Feature
>          Components: prepare
>    Affects Versions: 2.0-beta-8

> Currently, when preparing the release, the version to release is always the 
> next version which usually is the current version without the snapshot 
> extension.
> There are quiet a lot projects (Apache Felix, Sling and others) following an 
> even release numbering policy. So while the current development version is 
> odd (like 1.2.3-SNAPSHOT), the next released version will be 1.2.4.
> It would be nice if this could be made configuration through some 
> configuration property like
> <versionPolicy>next-even</versionPolicy> (with possible values being: next 
> (default, as-is), next-even, next-odd
> I briefly scanned through the code and it seems that adding support for this 
> requires changes in both, the release-manager and the release-plugin.
> If this feature gets accepted and if someone could give me some minor hints 
> how/where to add this I could come up with a patch.
