On SeptemMonnier announced that he would be stepping down as maintainer effective with the feature freeze of Emacs 25. Stefan Monnier and Chong Yidong have overseen maintenance since 2008. Richard Stallman has remained the principal maintainer of GNU Emacs, but he has stepped back from the role at times. Development took place in a single CVS trunk until 2008, and today uses the Git DVCS. The project has since adopted a public development mailing list and anonymous CVS access.

Īlthough users commonly submitted patches and Elisp code to the net.emacs newsgroup, participation in GNU Emacs development was relatively restricted until 1999, and was used as an example of the "Cathedral" development style in The Cathedral and the Bazaar.
Markus Hess exploited a security flaw in GNU Emacs's email subsystem in his 1986 cracking spree, in which he gained superuser access to Unix computers. It offered more features than Gosling Emacs, in particular a full-featured Lisp as its extension language, and soon replaced Gosling Emacs as the de facto Unix Emacs editor. GNU Emacs was later ported to the Unix operating system. In the current numbering scheme, a number with two components signifies a release version, with development versions having three components. A new third version number was added to represent changes made by user sites.
The "1" was dropped after version 1.12 as it was thought that the major number would never change, and thus the major version skipped from "1" to "13". Early versions of GNU Emacs were numbered as "1.x.x," with the initial digit denoting the version of the C core. The first widely distributed version of GNU Emacs was version 15.34, released later in 1985. Version 13, the first public release, was made on March 20, 1985. GNU Emacs is written in C and provides Emacs Lisp, also implemented in C, as an extension language. This became the first program released by the nascent GNU Project. GNU Emacs was initially based on Gosling Emacs, but Stallman's replacement of its Mocklisp interpreter with a true Lisp interpreter required that nearly all of its code be rewritten.

In 1976, Stallman wrote the first Emacs (“Editor MACroS”), and in 1984, began work on GNU Emacs, to produce a free software alternative to the proprietary Gosling Emacs. Richard Stallman, founder of the GNU Project and author of GNU Emacs The tag line for GNU Emacs is "the extensible self-documenting text editor". GNU Emacs is sometimes abbreviated as GNUMACS, especially to differentiate it from other EMACS variants. Throughout its history, GNU Emacs has been a central component of the GNU project, and a flagship of the free software movement. With proper support from the underlying system, GNU Emacs is able to display files in multiple character sets, and has been able to simultaneously display most human languages since at least 1999. GNU Emacs has been called "the most powerful text editor available today". In common with other varieties of Emacs, GNU Emacs is extensible using a Turing complete programming language. It was created by GNU Project founder Richard Stallman. GNU Emacs is a free software text editor. Unix-like ( GNU, Linux, macOS, BSDs, Solaris), Windows, MS-DOS
