The comment on the change is:
more detail on VVS singleton vs VelocityEngine

------------------------------------------------------------------------------
   * A: This is because Struts' !ActionServlet needs to be initialized before trying to use the Struts tools. Have a look at your web.xml file and make sure it starts up first. (Nathan Bubna)

   * Q: Why is the !VelocityServlet deprecated in favor of Tools !VelocityViewServlet?
-  * A: Some time back, the Velocity Developers decided it might be better to separate web functionality from the core Velocity engine. They decided that VelocityTools would be a better place to drop this functionality. Nobody has had the guts to remove !VelocityServlet from the Core, maybe in 2.0? <grin>  (Tim Colson)

-  * Q: (since VelocityTools 1.2) Why doesn't my non-web use of Velocity no longer work?
-  * A: Because it's no longer sharing a configuration with VVS. (Will Glass-Husain) '''TODO: add a link to the list archive.'''
+  * Q: (since VelocityTools 1.2) Why doesn't my non-web use of Velocity no longer work?  For example, I have code that allows the user to send email (based on a Velocity template) from a web app and it no longer works.
+  * A: One possibility is that it might not be sharing a configuration with VelocityViewServlet. More specifically, VelocityViewServlet was previously based on a singleton Velocity class.  If you had other uses of Velocity within the same webapp that also used the singleton Velocity class, they would share configuration data.  Now VelocityViewServlet uses a VelocityEngine instance to process templates.  You can get this instance for other uses of velocity by calling getVelocityEngine from a subclass.  Or, create and configure a second instance of VelocityEngine.  (while slightly more involved, this allows different configuration options which are often desired).  (Will Glass-Husain) 
  
  === DVSL & Anakia & Texen & Misc ===
   * Q: Is DVSL stable enough for use in production environment?
