+trickery is not needed anymore. The most visible changes are the following:
+
+- Pressing { and } will insert LaTeX's \{ and \} which show up as { }
+ in the printout. To get LaTeX's {} nesting, you need to type \{.
+
+- Fonts changes now really nest. Repeated application of a font change
+ will result in nested font changes! To remove a font change without
+ removing the "contents", it is now possible to "pull the argument"
+ like in other insets, i.e. put the cursor in the first position of
+ the inset and press 'backspace'.
