Support for traditional PKWARE encryption was added, Windows and CMake support and documentation were improved. CVE-2011-0421, opening archvies with more than 65535 entries, and various other bugs and memory leaks were fixed. zip_get_num_files() has been deprecated with the new function zip_get_num_files().
This release adds support for creating torrentzipped archives. It fixes various bugs and portability issues (especially on Windows). zip_source_file now only keeps the file open while actually reading from it, which allows adding more files than can be opened simultaneously.
New functions were added for adding directories to an archive and to clear the internal error state. Zip archives larger than 2 GB and streamed zip archives are now supported.
Support for reading and writing file and archive
comments has been added. A new member has been
added to struct zip_stat for future encryption
support, and zip_add now returns the index of the
added file. Because of the last two changes, the
shard library major version has been bumped.
