+One important change is to the behavior of character styles. By default,
+these now prohibit changes to the paragraph layout. Putting a description
+inside a character style typically results in invalid LaTeX code, so this
+makes certain mistakes harder to make. Power users who have taken advantage
+of the previous behavior can restore it by adding "ForcePlain 0" to the
+declaration of the character style, so long as this is done after "LyXType
+charstyle" has been declared.
