Editing NCSA Mosaic (section)

== Legacy ==
[[Netscape Navigator]] was later developed by [[Netscape]], which employed many of the original Mosaic authors; however, it intentionally shared no code with Mosaic. Netscape Navigator's code descendant is [[Firefox|Mozilla Firefox]].<ref name=Clark>{{cite book|last=Clark|first=Jim|title=Netscape Time|url=https://archive.org/details/netscapetimemaki00clar|url-access=registration|publisher=St. Martin's Press|year=1999|isbn=9780312199340}}</ref>{{Page needed|date=March 2022}}

After NCSA stopped work on Mosaic, development of the NCSA Mosaic for the X Window System source code was continued by several independent groups. These independent development efforts include mMosaic (multicast Mosaic)<ref>{{cite web |url=http://www.w3.org/AudioVideo/9610_Workshop/paper05/paper05.html |title=W3C mMosaic |last=dauphin |first=Gilles |publisher=World Wide Web Consortium |year=1996 |access-date=2007-11-02}}</ref> which ceased development in early 2004, and Mosaic-CK and VMS Mosaic.

'''VMS Mosaic''', a version specifically targeting [[OpenVMS]] operating system, is one of the longest-lived efforts to maintain Mosaic. Using the VMS support already built-in in original version (Bjorn S. Nilsson ported Mosaic 1.2 to VMS in the summer of 1993),<ref>{{cite web |url=ftp://ftp.ncsa.uiuc.edu/Web/Mosaic/Contrib/README.VMS |title=README.VMS |year=1993 |publisher=National Center for Supercomputing Applications |first=Bjorn |last=Nilsson |access-date=2007-11-02 }}{{Dead link|date=April 2020 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> developers incorporated a substantial part of the HTML engine from mMosaic, another defunct flavor of the browser.<ref name="changehistory">{{Cite web |url=http://wvnvms.wvnet.edu/vmswww/mosaic/versions.html |title=NCSA and VMS Mosaic Version Information |access-date=2012-08-02 |archive-url=https://web.archive.org/web/20080704121456/http://wvnvms.wvnet.edu/vmswww/mosaic/versions.html |archive-date=2008-07-04 |url-status=dead }}</ref> As of the most recent version (4.2), released in 2007, VMS Mosaic supported [[HTML]] 4.0, [[OpenSSL]], [[HTTP cookie|cookies]], and various image formats including [[Graphics Interchange Format|GIF]], [[JPEG]], [[Portable Network Graphics|PNG]], [[BMP file format|BMP]], [[Truevision TGA|TGA]], [[Tag Image File Format|TIFF]] and [[JPEG 2000]] image formats.<ref>{{cite web |url=http://www.openvms.org/stories.php?story=07/09/03/1740114 |title=OpenVMS.org – OpenVMS Community Portal (VMS Mosaic V4.2) |publisher=OpenVMS.org |year=2007 |access-date=2007-11-02 |archive-url=https://web.archive.org/web/20070911192043/http://www.openvms.org/stories.php?story=07%2F09%2F03%2F1740114 |archive-date=2007-09-11 |url-status=dead }}</ref> The browser works on [[VAX]], [[DEC Alpha|Alpha]], and [[Itanium]] platforms.<ref name=VMSMosaic>{{cite web |url=http://h71000.www7.hp.com/freeware/freeware80/mosaic40/freeware_readme.txt |year=2006 |title=Mosaic 4.0 freeware_readme.txt |publisher=Hewlett-Packard Development Company, L.P |access-date=2007-11-02 }}{{Dead link|date=April 2020 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

Another long-lived version, '''Mosaic-CK''', developed by Cameron Kaiser, was last released (version 2.7ck9) on July 11, 2010; a maintenance release with minor compatibility fixes (version 2.7ck10) was released on January 9, 2015, followed by another one (2.7ck11) in October 2015.<ref name="CK">{{Cite web|url=http://www.floodgap.com/retrotech/machten/mosaic/|title=Floodgap Mosaic-CK: an unsupported updated port of the NCSA Mosaic web browser|website=www.floodgap.com}}</ref> The stated goal of the project is "[[Lynx (web browser)|Lynx]] with graphics" and runs on Mac OS X, Power [[MachTen]], [[Linux]] and other compatible Unix-like [[Operating system|OS]]s.<ref name="CK" />
