1 GNU Emacs history, versions, and release dates
3 For more details about release contents, see the NEWS* files.
5 Most of the development history of GNU Emacs is available in its
6 source code repository <http://savannah.gnu.org/git/?group=emacs>.
7 However, in the early days GNU Emacs was developed without using
8 version control systems and was published via half-inch 9-track
9 1600-bpi magnetic tape reels. Although information about this early
10 development is sketchy, the following text summarizes what is known.
12 EMACS started out as a set of macros atop the TECO text editor, and
13 was first operational in late 1976. It was inspired by earlier work
14 such as the E editor of Stanford, and was based on older TECO macro
15 sets. EMACS in turn inspired several similar editors. See:

17 Display Editor. AI Memo 519a, MIT, 1981-03-26
18 <http://dspace.mit.edu/bitstream/handle/1721.1/5736/AIM-519A.pdf>.
20 In 1984, work began on GNU Emacs, a fresh implementation designed to
21 run on GNU and GNU-like systems, with a full-featured Lisp at its
22 core. GNU Emacs 1.0 through 1.12 were released in early 1985. The
23 next version after 1.12 was 13; this was the initial public release.
25 Here is a list of known GNU Emacs stable releases starting with the
26 initial public release. Entries in the list are of the form "GNU
27 Emacs N (DATE) TAG", where N is the version number, DATE the release
28 date, and TAG (if present) the corresponding tag in the source code
29 repository. Any commentary about the version starts on the next line.
30 Dates are approximate in the following list; some are when the version
31 was made, some are when it was announced.
