 ### Updates since last release
+
+* v1.91 Replace all KaTeX woff2 fonts with woff versions.
+  This fixes the big delimiters problem. I hope that WebView in a later
+  version of JavaFX will accept woff2 fonts and I can switch back.
+* Add WebEngine debugging code from debugWebEngine branch.
+* Add div margin styles to improve vertical spacing of typeset maths.
+* Remove \> controls (tabs) from fmprint output, which don't seem to serve any
+  useful purpose, using katexMacros.
+* Always insert parentheses when calling a function using the pop-up keyboard,
+  and rewrite ln to log.
