Version 4.1 incorporates the latest Zip and compression standards by supporting the LZMA algorithm, used by WinZip 12. UTF-8 character encoding in headers is also provided for improved support of international characters in filenames and comments. These enhancements ensure that developers can respond quickly to changes in the industry and keep a step ahead of their competition. (Note: The version number has also been synchronized with our other .NET Zip products.)
