• 2006-03-20: In anticipation of releasing the new version of JR (2.00001) in about a week, we've reorganized the web pages.  Some previous pages (such as installation and execution instructions, and "code extracts") have been moved to pages for a particular version of JR.  Please let us know if you find something broken!
  
• 2006-03-10: Francois Kilchoer of L'Ecole d'ingénieurs et d'architectes de Fribourg/Hochschule für Technik und Architektur Freiburg has developed a vim syntax file for JR that provides keyword highlighting, etc.  See "editing JR programs" on the "translating and executing JR programs" page for a particular version of JR.
  
• 2005-12-04: we have been working on a new version of JR (2.00001).  It is a modified implementation of JR using Java 1.5 (aka Java 5.0) and extends JR with Java 1.5's new language features.  We've been using this new implementation locally for a few months and it is nearly ready for public release.  See Angela Chan's thesis for details.
• 2005-07-11: the new release of JR (1.00061) is available!  It contains the concurrent invocation statement, timeout arm on inni (see vsuite/inni/timeout in JR's distribution for examples), better support for Cygwin, and some cleanup and performance improvements.  (As you can see below, we were overly optimistic about when we would have this version ready.  Sorry for any inconvenience.)  Important note to current users: this version replaces jr.jar with jrt.jar and jrx.jar, so you'll  need to change your CLASSPATH accordingly; for details see "translating and executing JR programs" page for a particular version of JR.
