There is a new version of frigcal, a Python 3.X/tkinter desktop GUI calendar program. This version makes an install of the third-party Pillow (a.k.a. PIL) library optional for some combinations of image-file type and Python version; addresses incompatible changes in color names in the Tk 8.6 library underlying tkinter in Python 3.4 and later; and on Linux improves the behavior of modal dialogs and window icons.
