B.1 Version 6.4 =============== Compatibility changes for luatex 1.9 and later. The location of pdftops is no longer configurable; it is only searched for on the searchpath. Some corner cases should be handled more successfully. The GUI now requires Tcl/Tk version 8.5 or higher. On Windows, epspdf.tlu is now invoked via a batchfile. This should prevent black console windows popping up.
