What's New!! in v2010 R2

NEW: Ability to hide calls to methods and properties from external assemblies (such as those from the .Net framework).
NEW: Ability to hide calls to unrenamed methods and properties from the project assemblies. So, even if some methods and properties must be excluded from renaming, its impossible to determine when, where and how they are used.

NEW: General UI improvements and much faster obfuscation.

What's New!! in v2009

NEW: Deep integration (merging) of the LogicNP.CryptoLicensing.dll assembly in your assembly to remove obvious links between your assembly and CryptoLicensing, making it even more difficult to reverse-engineer or crack your assemblies.
NEW: Support for .Net Framework 4.0 Beta 2 and Visual Studio 2010.
NEW: Improved support for Silverlight 2.0 and 3.0.
NEW: Improved support for Compact Framework.
