 Changelog
 =========
 
+0.28.0
+------
+
+Includes a wide variety of improvements:
+
+- support ``currentTime`` attr of audio/video elements
+- support for the ``files`` attribute from the target of input elements
+- model children are passed to the Javascript ``mount()`` function
+- began to add tests to client-side javascript
+- add a ``mountLayoutWithWebSocket`` function to ``idom-client-react``
+
+and breaking changes, the most significant of which are:
+
+- Refactor existing server implementations as functions adhering to a protocol. This
+  greatly simplified much of the code responsible for setting up servers and avoids
+  the use of inheritance.
+- Switch to a monorepo-style structure for Javascript enabling a greater separation of
+  concerns and common workspace scripts in ``package.json``.
+- Use a ``loadImportSource()`` function instead of trying to infer the path to dynamic
+  modules which was brittle and inflexible. Allowing the specific client implementation
+  to discover where "import sources" are located means ``idom-client-react`` doesn't
+  need to try and devise a solution that will work for all cases. The fallout from this
+  change is the addition of `importSource.sourceType` which, for the moment can either
+  be ``"NAME"`` or ``"URL"`` where the former indicates the client is expected to know
+  where to find a module of that name, and the latter should (usually) be passed on to
+  ``import()``
+
