Check out the Rankophilia Wikia
- JFLAP Wiki Born!
- July 2008 - JFLAP now has two listservs. To join, go to lists.duke.edu You do not need to be a member of Duke to join the listserv.
- jflap-announce@duke.edu - for announcements on new releases of JFLAP or new info on the JFLAP web page
- jflap-discuss@duke.edu - for anyone to have discussions about JFLAP
- July 27, 2018 - JFLAP 7.1 now available. We have updated JFLAP 7 to Java 8 and made some changes to Turing machines.
- We recommend using JFLAP 7.1 and NOT JFLAP 8 Beta as the Beta version was never finished and doesn't cover as many topics.
