Editing DOS Navigator (section)

== History ==
The initial version of DN I (v 0.90) was released in 1991, and written by Stefan Tanurkov, Andrew Zabolotny and Sergey Melnik (all from [[Chișinău]], [[Moldova]]). After that, DN was rewritten using [[Turbo Vision]] by Stefan Tanurkov and Dmitry Dotsenko (Dotsenko developed DN at [[Moscow State University]]). These versions are sometimes referred as DN II.

In 1993, Slava Filimonov invited Stefan to join him to continue producing and publishing DN with joint efforts. Slava programmed new components, design and made countless optimizations and improvements. He wrote a new [[software key]] protection system that remained unbroken for almost four years after its introduction.<ref name="Fravia_1997"/>

DN II was actively developed until the start of 1995, until version 1.35.<ref name="Bezroukov_2011_DN"/> Several other programmers participated in development after version 1.35. Starting from version 1.37, Filimonov and Ilya Bagdasarov were in charge of bug-fixing. Filimonov and Bagdasarov solely maintained, developed and released versions 1.37 through 1.39. After they left, DN was maintained again by Tanurkov and Maxim Masiutin.

In 1998, the development mostly took a bug-fixing direction as Ritlabs' product [[The Bat!]] became a more promising software product with much better commercial potential. The last [[shareware]] version was 1.50. In late 1999, Ritlabs decided to make version 1.51 of the DOS Navigator completely free with freely available [[source code]].

Several open source DN branches currently exist including win32/dpmi/os2 version "dn/2"<ref>{{cite web |url=http://www.dnosp.com/ |title = DOS Navigator Open Source Project}}</ref> and Linux [[porting|port]] attempt "dn2l".<ref>{{Cite web|url=https://github.com/unxed/dn2l/|title=Dn2l|website=[[GitHub]]|date=8 November 2021}}</ref>
