 IV. REMARKS ON THIS RELEASE
 
-Version 2.16 adds some control over spacing around aligned/gathered and
-adjustments to the generalized fraction code so that it works in xetex.
+Version 2.17
+Fixes a bug in the spacing around the closing delimiter in generalised
+fractions in xetex and luatex version added in release 2.16.
+Fixes a bug that overfull lines did not always produce warnings.
