  • Upgraded VelocityStruts dependencies to those for Struts 1.3.x series and updated "struts" example app according to provided directions. (ndb)
  • Replaced "layout" example with new "showcase" example to interactively demonstrate all tools and the VelocityLayoutServlet. (ndb)

  • Added configurable getSelf() function to LinkTool to make self-referencing links easier. (ndb)
  • Added create() methods to CookieTool to support more complex Cookie creation. (ndb)
  • Added ContextTool for convenient access to context data and meta-data. (ndb)
  • VELTOOLS-71: Overhauled ant build process: dependencies are now automatically download, jars have manifests, checksums are auto-generated, and more. Also, building with JDK 1.3 is no longer supported. (ndb)
  • Updated license headers and notices to comply with new ASF policy. (henning)
  • Made auto-alternate default of AlternatorTool configurable via toolbox config. (ndb)

  • Fixed incomplete escaping in ValidatorTool (patch from Christopher Schultz. Jira Issue VELTOOLS-52). (ndb)
  • Fixed infinite loop logging problem with Tomcat 5.5 in the "simple" example webapp. (ndb)

  • Upgraded jars from Velocity 1.3.1 to Velocity 1.4 (ndb)
  • Simplified MessageTool interface to support $text.this.that syntax instead of just $text.get('this.that') (ndb)
