+1.7   2019-10-10
+      - Fix - because of a change in a macro name, it stopped
+        working with xe/lua
+      - Multi-level comparisons (up to 3), to better sort the items.
+      
 1.6   2019-09-30
       - Package option 'babel', which wraps each entry not in the main
         language with \foreignlanguage (or other macro).

 macro is \verb|\esindexlanguage|, which by default is `let' to the
 \textsf{babel} macro.
 
+Version 1.7 (besides fixing a bug with xe/lua) adds multilevel
+comparisons (up to three levels, ie, primary, secondary and tertiary).
+For example:
+\begin{verbatim}
+\esindexreplacesub{å}{a}{2}%
+\esindexreplacesub{à}{a}{1}%
+\end{verbatim}
+creates a two-level key sorting \verb|à| before \verb|å|. For a
+three-level key use \verb|\esindexreplacesubsub| (with 4 arguments). With
+\verb|\esindexexpandkeys| the three levels are expanded. (Internally,
+with the definitions above the key for \verb|ràpid| is
+\verb|rapid^^Ar1pid|.)
