| 2 Version 1.1, February 14h, 2010 | |
| 3 part of the MiniZip project - ( http://www.winimage.com/zLibDll/minizip.html ) | |

| 7 Modifications for Zip64 support | |

| 12 Changes | |
| 13 Oct-2009 - Mathias Svensson - Remove old C style function prototypes | |
| 14 Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives | |
| 15 Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions. | |
| 16 Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data | |
| 17 It is used when recreting zip archive with RAW when deleting items from a zip. | |
| 3284 | 18 ZIP64 data is automatically added to items that needs it, and existing ZIP64 data need to be removed. |
| 102 | 19 Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required) |
| 20 Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer | |
