As the volume of a detail style considerably increased compared with earlier versions, from version 17.2 on the file will only be saved as binary file with the file extension .stx. All commands for loading a detail style require that the style files in this format.
Tip: The former text file format (file extension
.sty) will not be supported any more from version 18.0 on and, if need be, must be converted together with the previous version.
