 The jar to launch the Tetrad GUI is here (please download this one and delete any old ones):
 
-https://s01.oss.sonatype.org/content/repositories/releases/io/github/cmu-phil/tetrad-gui/7.2.0/tetrad-gui-7.2.0-launch.jar
+https://s01.oss.sonatype.org/content/repositories/releases/io/github/cmu-phil/tetrad-gui/7.2.1/tetrad-gui-7.2.1-launch.jar
 
 The application will work on all major platforms once a recent version of the Java JRE is installed. (Corretto 18 is fine, for instance.) You may be able to launch it by double clicking the jar file name, though on a Mac, this presents some security challenges--
