+What's new in version 2.1.5?
+----------------------------
+
+We have fixed a number of bugs and made a number of improvements. Many
+of these were minor, but there were a few crashes we fixed, too.
+
+Please note that this is the final release in the 2.1.x series. It is
+intended for users who for some reason do not wish to upgrade to 2.2.x
+at this time. We strongly encourage all such users to upgrade to this
+version.
+
+One of the main features of 2.1.5 is its ability to read and write files
+in the 2.2.x format. Since the conversion process back and forth usually
+will not leave one with an identical file, however, we do not recommend
+attempting to collaborate with users of 2.2.x.
