The Zip capabilities in version 4.2 of Xceed Zip for .NET CF boast their most exciting and significant performance increase yet. Creating and updating zip files can be significantly faster, thanks to a greatly reduced use of temporary files.

Added a TarEvents class (currently undocumented). The class should be used like the ZipEvents class. For now, TarEvents only contains the ReadingTarItemProgression event. It will be triggered during the initial reading of the Tar archive. The Tar format does not allow the component to know the total number of items without a large time penalty. So true progression with a percentage is not possible. The event will report the value 0 in the 'Total' property until the last time the event is triggered. Then, the value in 'Total' will be the total number of items read. This will also serve to indicate that the operation has completed.
