+# Release 4.0.0
+
+Multiple (self-contained) example programs have been added to illustrate the features of this
+libary. Otherwise, just smaller clean up tasks.
+
+As part of the clean up, the `DigestTypes` enum has been moved from the openssl namespace into
+the mococrw namespace. A `using` statement  was added to make this backwards-compatible API-wise.
+It is, however, an ABI change. Thus, this is a new major version release.
+
+## Details
