DevelopmentNoah Morgan originally created LARN 12.0 and released the UNIX version to the USENET in 1986. Don Kneller ported the UNIX version to MSDOS (both IBM PCs and DEC Rainbows).
Kevin Routley has been working on LARN enhancements on and off for the past two years. Version 12.1 had a limited distribution.
Version 12.2 is the last version from Routley that will maintain savefile compatibility with version 12.0 savefiles. Later versions (if any) were stated be released as Shareware.
