About:
UnZip will list, test, or extract files from a ZIP archive, commonly found on DOS and Windows systems. A companion program, Zip, creates ZIP archives; both are part of the Info-ZIP project. Both programs are compatible with archives created by PKWARE's PKZIP or Nico Mak's WinZip, but in many cases the program options or default behaviors differ.

Release focus: Minor bugfixes

Changes:
Support for PKWARE's Deflate64 compression method, support for simple "execute command after extraction" in UnZipSFX (compile sources with CHEAP_SFX_AUTORUN defined), and a fix for a directory-traversal security hole with a new "-:" option to override.

That is incorrect. The zlib in-memory, deflate/inflate compression library is there (or at http://www.zlib.org/), but Zip and UnZip are separate (and older) command-line utilities for processing zipfiles. They live at http://www.info-zip.org/pub/infozip/ (web pages) and ftp://ftp.info-zip.org/pub/infozip/ (files).

Note that UnZip can use zlib, but this is optional.
