+-------------------
+
+Security
+~~~~~~~~
+
+- Prevent users from receiving an invalid authority parsed from a malicious
+  URL. Previously we did not stop parsing the authority section at the first
+  backslash (``\\``) character. As a result, it was possible to trick our
+  parser into parsing up to the first forward-slash (``/``) and thus 
+  generating an invalid authority.

+  See also `GitHub pr-64`_ and `the blog post that sparked this change`_
+
+Bug Fixes and Features
+~~~~~~~~~~~~~~~~~~~~~~
+
+- Add ``from_uri`` to ``URIBuilder`` to allow creation of a ``URIBuilder``
+  from an existing URI.
+
+  See also `GitHub pr-63`_
+
+- Fix a typographical error in our documentation.
