Hi, I downloaded 2.11.51, and there are two problems: 1) some syntaxes are changed such as \sustainOn and \sustainOff. I have no time to re-read the manuals, but the news page has no indication of it at the top. So \setTextCresc and \setHairpinCresc are also obsolete. Could someone provide a list of the syntax changes? 2 the compilation is successful, but a dialog box comes up: gs.exe encounters a problem and needs to be closed. I don't know whether the PDF is ok. But why gs.exe has this error?
