-Some text here.
+We're happy to announce that the latest release of Nim, version 0.15.0, is now
+available!
+
+As always, you can grab the latest version from the
+`downloads page <http://nim-lang.org/download.html>`_.
+
+This release includes almost 180 bug fixes and improvements. To see a full list
+of changes, take a look at the detailed changelog
+`below <#changelog>`_.
+
+Some of the most significant changes in this release include: improvements to
+the documentation, addition of a new ``multisync`` macro, and a new
+``HttpClient`` implementation.
+
+Documentation
+~~~~~~~~~~~~~
+
+All pages in the documentation now contain a search box and a drop down to
+select how procedures should be sorted. This allows you to search for
+procedures, types, macros and more from any documentation page.

+  </a>
+
+Sorting the procedures by type shows a more natural table of contents. This
+should also help you to find procedures and other identifiers.

+
+Multisync macro
+~~~~~~~~~~~~~~~
+
+The ``multisync`` macro was implemented to enable you to define both
+synchronous and asynchronous IO procedures without having to duplicate a
+lot of code.
+
+As an example, consider the ``recvTwice`` procedure below:
+
+.. code-block:: nim
+  proc recvTwice(socket: Socket | AsyncSocket): Future[string] {.multisync.} =
+    result = ""
+    result.add(await socket.recv(25))
+    result.add(await socket.recv(20))
+
+The ``multisync`` macro will transform this procedure into the following:
+
+.. code-block:: nim
+  proc recvTwice(socket: Socket): string =
+    result = ""
+    result.add(socket.recv(25))
+    result.add(socket.recv(20))
+
+  proc recvTwice(socket: AsyncSocket): Future[string] {.async.} =
+    result = ""
+    result.add(await socket.recv(25))
+    result.add(await socket.recv(20))
+
+Allowing you to use ``recvTwice`` with both synchronous and asynchronous sockets.
+
+HttpClient
+~~~~~~~~~~
+
+Many of the ``httpclient`` module's procedures have been deprecated in
+favour of a new implementation using the ``multisync`` macro. There are now
+two types: ``HttpClient`` and ``AsyncHttpClient``. Both of these implement the
+same procedures and functionality, the only difference is timeout support and
+whether they are blocking or not.
+
+See the `httpclient <http://nim-lang.org/docs/httpclient.html>`_ module
+documentation for more information.
