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.
|
|
|
18 ZIP64 data is automaticly added to items that needs it, and existing ZIP64 data need to be removed.
|
|
|
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
