-Files: utf8.h utf8cpp.html ReleaseNotes
+- Feature request [1569543]: Add utf8 iterator adapter class
+- Feature request [1569479]: Add replace_invalid function
+- Reorganized the source code: rather than a single header file, the library now resides in three separate ones. To maintain the backward compatibility, there is also a convenience header utf8.h that includes all the other ones.
+- The requironment for octet_iterator is bidirectional, rather than random access, although in practice it probably doesn't mean a lot.
 
+Files included in the release: utf8.h, core.h, checked.h, unchecked.h, utf8cpp.html, ReleaseNotes
