+
+Hot out of the oven! We just released Elixir v0.7.2 with a number of delicious improvements.
+
+One of the most important changes in this minor release is a partial rehaul of
+the type specification syntax.
+
+Here's the gist:
+
+    @spec myfun(integer), do: integer
+    # becomes
+    @spec myfun(integer) :: integer
+
+    @type a :: fun
+    # becomes
+    @type a :: (... -> any) or ((...) -> any) or (fun(...) -> any)
+    @type a :: fun(do: integer)
+    # becomes
+    @type a :: (() -> integer) or (fun() -> integer)
+    @type a :: fun(integer, do: integer)
+    # becomes
+    @type a :: (integer -> integer) or ((integer) -> integer) or (fun(integer) -> integer)
+    @type a :: fun(integer, integer, do: integer)
+    # becomes
+    @type a :: (integer, integer -> integer) or ((integer, integer) -> integer) or (fun(integer, integer) -> integer)
+
+Another change is that Mix now echoes the output of external tools
+such as git and rebar, and handles exit status correctly. This have previously
+led to some less-than-perfect workflows.
+
+We've also added a more compact and visual form of the `function` helper. Now, instead of `function(Enum, :all?, 2)` you can use `function(Enum.all?/2)`.
+
+We've also figured out how to achieve an up to 6x [performance increase](https://github.com/elixir-lang/elixir/blob/v0.7.2/lib/elixir/lib/kernel.ex#L1386-L1417) when using records.
+
+...and [many other fixes & improvements](https://github.com/elixir-lang/elixir/blob/v0.7.2/CHANGELOG.md).
+
+Lastly, but not least importantly, I'd like to mention that we're very excited about how the community around Elixir is building up. Thank you all for being around and supporting us!
