<\body> 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 , there are small spaces around the minus sign ; this is no longer the case in , where we use the minus as aprefix. Similarly, the spacing inside lists of operators > is now correct. However, the modification may alter the spacing inside some 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, > and > are now obtained by typing . The shortcuts for >, > and have also been changed. For more information, please refer to the documentation on . At this place, you will also find more information about the newly added semantic editing features.
