The 3.0.0 Installer
Your first encounter with the major new 3.0.0 release will be the new installer. It looks very similar to the old one but there have been a lot of improvements under the hood. It installs the prerequisites (Java and .NET), allows you to optionally bind the .mpr extension to the version you are installing and gives shorter names to the shortcuts so that you can quickly see version numbers. Also, if you want to get rid of a specific version the uninstaller does its work without leaving traces now.
