History
UnZip
UnZip 1.0 (March 1989) was released by Samuel M. Smith. It was written in Pascal and C. Pascal was abandoned soon after.
UnZip 2.0 (September 1989) was released by Samuel M. Smith. It included support for the "unimploding" (method 6) introduced by PKZIP 1.01. George Sipe created Unix version.
UnZip 2.0a (December 1989) was released by Carl Mascott and John Cowan.[3]
In Spring 1990, Info-ZIP was formed as a
UnZip 3.0 (May 1990) became the first public release by Info-ZIP group.
UnZip 4.0 (December 1990) adds support of "central directory" within .ZIP archive.[3]
UnZip 5.0 (August 1992) introduces support of
Method 8 has become the de facto base standard for ZIP archives.In 1994 and 1995 Info-ZIP turned a corner, and effectively became the de facto ZIP program on non-MS-DOS systems. A huge number of ports were released that year, including numerous minicomputers, mainframes and practically every microcomputer ever developed.[citation needed]
UnZip 5.41 (April 2000) was relicensed under Info-ZIP License.[3]
UnZip 5.50 (February 2002) adds support of
UnZip 6.0 adds support of "Zip64" .ZIP archive and bzip2 (method 12) decompression.[5] Support for bzip2-style compression was also in Zip from 3.0f beta.[6]
Zip
Zip 1.9 (August 1992) introduces support of
Zip 2.0 (September 1993) has many portability improvements.
Zip 2.1 (May 1996) added new "UNIX" time info to preserve file times across timezones and OSes.
Zip 2.3 (December 1999) was the first Info-ZIP archiver tool under the new
Zip 3.0 (2008-07-07) supports "Zip64" .ZIP archive, more than 65536 files per archive, multi-part archive, bzip2 compression, Unicode (UTF-8) filename and (partial) comment, Unix 32-bit UIDs/GIDs
WiZ
WiZ 4.0 (November 1997) was released by Info-ZIP.[3]
WiZ 5.01 (April 2000) was relicensed under Info-ZIP License.[3]
MacZip
MacZip 1.05 (July 2000) was released under Info-ZIP License.
MacZip 1.06 was released in February 2001. It was written by Dirk Hasse.[3]
Forks and patches
As a slowly-updated open software package, many patches have been written by various Linux distributions to improve info-zip tools. In addition, from 2015 to 2019, 14 unzip vulnerabilities have been published on the CVE list without version or website updates from info-zip.[7] (Three CVEs from 2014 in oCERT-2014-011 are left out of most statistics; info-zip did provide patches on their now-defunct forum.)[8]
Mark Adler has a set of patches for unzip 6.0 that detects zip bombs of the overlapping type. This issue has a CVE ID of CVE-2019-13232.[9]
The Debian project provides various patches to correct typographical errors and security issues, including the 17 unzip CVEs. It also hardens against format string injection and other obvious security issues.[10]

Official betas
Some official improvements to zip and unzip are stuck in beta-stage as zip 3.1c and unzip 6.10b from 2015. Among other things, both added support for PPMd8 and LZMA compressions in .zipx files, support for AES encryption, and included iconv-based Unicode improvements (based on unzip-iconv).[14] A newer release candidate, Zip 3.1d, appeared on the official FTP site in 2015, but the SourceForge page was not updated. Partially due to the added compressors, the zipped file size increased from 1.4 MB (3.1c) to 2.9 MB (3.1d).
The antinode.info FTP site seems to be hosting an even more cutting-edge source of info-zip utilities. Individual revisions are organized into folders containing files differing from the previous revision, and zip archives for sources are occasionally released. As of May 2023[update], the site provides Unzip 6.10c (rev. 25, 21 Dec 2018) and an loose-file development version of Zip 3.1e (rev. 21, 14 Dec 2021).[15] The owner of the site, Steven Schweda, maintains these versions.[16] Schweda is a member of the original info-zip team.[17]
Replacements
FreeBSD has opted to replace info-zip utilities. It produces a command-line compatible version of unzip based on libarchive, which also supports zipx and AES.[18][19]
