+  <expand|tmdoc-title|Improved spacing inside formulas (1.0.7.10)>
+
+  In the new version, the spacing around mathematical operators has been made
+  dependent on the semantic context. For instance, when used as an infix
+  operator in a subtraction <expand|math|x-y>, there is are small spaces around the
+  minus sign <expand|math|->; this is no longer the case in <expand|math|-x>, where we
+  using it as a<expand|nbsp>prefix. Similarly, the spacing inside lists of operators
+  <expand|math|+,-,\<times\>> is now correct. However, the modification may modify
+  some of the spacing for formulas in existing documents. For critical
+  documents, you may thus want to review the line breaking.
+
+  Some of the keyboard shortcuts inside formulas have also been modified. For
+  instance, <expand|math|\<wedge\>> and <expand|math|\<vee\>> are now obtained by typing
+  <expand|key|&> <expand|abbr|resp.> <expand|key|%>. The shortcuts for <expand|math|\<in\>>,
+  <expand|math|\<prec\>> and <expand|math|\|> have also been changed. For more information,
+  please refer to the documentation on <expand|hlink|editing mathematical
+  formulas|$TEXMACS_DOC_PATH/main/math/man-math.en.tm>. At this place, you
+  will also find more information about the newly added semantic editing
+  features.
