The ANT tasks are refactored so that developers can easily find the targets they need and make their own extensions. Developers can still use Java Command Line as before. Ant Build Script " conductor.xml" is marked as deprecated, but developers can still use it as before. " build.xml" is the renamed version of " conductor.xml", and developers can use it as what they do with " conductor.xml". New users are suggested to use those separated build scripts like " build_dita2*.xml". The original demo ant script " build.xml" is renamed to " build_demo.xml". " build_demo.xml" should be used to verify the functions of the toolkit after this release.
