 	This release adds a couple of new features.
 
-XXX	The shared library names???
+	The library is mostly source-level compatible with nettle-3.0.
+	It is however not binary compatible, due to the introduction
+	of versioned symbols, and extensions to the base64 context
+	structs. The shared library names are libnettle.so.6.0 and
+	libhogweed.so.4.0, with sonames libnettle.so.6 and
+	libhogweed.so.4.
 
 	Bug fixes:
 
+	* Fixed a missing include of <limits.h>, which made the
+	  camellia implementation fail on all 64-bit non-x86
+	  platforms.
+
 	* Eliminate out-of-bounds reads in the C implementation of
 	  memxor (related to valgrind's --partial-loads-ok flag).
