+16.2.1
+------
+*(April 29, 2016)*
+
+This version sees the soft debut of [socketutils][socketutils], which
+includes wrappers and tools for working with the built-in socket. A
+lot of [socketutils.BufferedSocket][socketutils.BufferedSocket] changes.
+
+  * [BufferedSocket.recv_until][socketutils.BufferedSocket.recv_until] now
+    supports multibyte delimiters and also includes the delimiter in its returns.
+  * Better BufferedSocket timeout discipline throughout.
+  * Various BufferedSocket argument name changes, *maxbytes* became
+    *maxsize*, *n* became *size*, *marker* became *delimiter*, etc.
+  * [BufferedSocket][socketutils.BufferedSocket] BufferedSocket became
+    threadsafe
+  * [BufferedSocket.recv][socket.BufferedSocket.recv] now always returns the
+    contents of the internal buffer before doing a socket call.
+  * [BufferedSocket.recv_close][BufferedSocket.recv_close] now exists
+    to receive until the sending end closes the connection.
+  * Can now pass *recvsize* to
+    [BufferedSocket][socketutils.BufferedSocket] constructor to tune
+    the size passed to the lower-level recv call.
+  * [socketutils][socketutils] got documented and tested.
