1983 to 1990

Shortly after the publication of Steele-1983, the File effectively stopped growing and changing. Originally, this was due to a desire to freeze the file temporarily to ease the production of Steele-1983, but external conditions caused the "temporary" freeze to become permanent.

. The File's compilers, already dispersed, moved on to other things. Steele-1983 was partly a monument to what its authors thought was a dying tradition; no one involved realized at the time just how wide its influence was to be.

As mentioned in some editions:

, circulated even in cultures far removed from MIT's; the content exerted a strong and continuing influence on hackish slang and humor. Even as the advent of the microcomputer and other trends fueled a tremendous expansion of hackerdom, the File (and related materials like the AI Koans in Appendix A) came to be seen as a sort of sacred epic, a hacker-culture Matter of Britain

 chronicling the heroic exploits of the Knights of the Lab. The pace of change in hackerdom at large accelerated tremendously, but the Jargon File passed from living document to icon and remained essentially untouched for seven years.


1990 and later

A new revision was begun in 1990, which contained nearly the entire text of a late version of jargon-1 (a few obsolete PDP-10-related entries were dropped after consultation with the editors of Steele-1983). It merged in about 80% of the Steele-1983 text, omitting some framing material and a very few entries introduced in Steele-1983 that are now only of historical interest.

The new version cast a wider net than the old Jargon File; its aim was to cover not just AI or PDP-10 hacker culture but all of the technical computing cultures in which the true hacker-nature is manifested. More than half of the entries now derive from Usenet

 maintains the new File with assistance from Guy Steele, and is the credited editor of the print version, The New Hacker's Dictionary. Some of the changes made under his watch have been controversial; early critics accused Raymond of unfairly changing the file's focus to the Unix hacker culture instead of the older hacker cultures where the Jargon File originated. Raymond has responded by saying that the nature of hacking had changed and the Jargon File should report on hacker culture, and not attempt to enshrine it. More recently, Raymond has been accused of adding terms to the Jargon File that appear to have been used primarily by himself, and of altering the file to reflect his own political views.
