- GNU Emacs history, versions, and release dates
- For more details about release contents, see the NEWS* files.
- Most of the development history of GNU Emacs is available in its
- source code repository <http://savannah.gnu.org/git/?group=emacs>.
- However, in the early days GNU Emacs was developed without using
- version control systems and was published via half-inch 9-track
- 1600-bpi magnetic tape reels. Although information about this early
- development is sketchy, the following text summarizes what is known.
- EMACS started out as a set of macros atop the TECO text editor, and
- was first operational in late 1976. It was inspired by earlier work
- such as the E editor of Stanford, and was based on older TECO macro
- sets. EMACS in turn inspired several similar editors. See:
- Stallman RM. EMACS: The Extensible, Customizable Self-Documenting
- Display Editor. AI Memo 519a, MIT, 1981-03-26
- <http://dspace.mit.edu/bitstream/handle/1721.1/5736/AIM-519A.pdf>.
- In 1984, work began on GNU Emacs, a fresh implementation designed to
- run on GNU and GNU-like systems, with a full-featured Lisp at its
- core. GNU Emacs 1.0 through 1.12 were released in early 1985. The
- next version after 1.12 was 13; this was the initial public release.
- Here is a list of known GNU Emacs stable releases starting with the
- initial public release. Entries in the list are of the form "GNU
- Emacs N (DATE) TAG", where N is the version number, DATE the release
- date, and TAG (if present) the corresponding tag in the source code
- repository. Any commentary about the version starts on the next line.
- Dates are approximate in the following list; some are when the version
- was made, some are when it was announced.
