To ensure consistency, and to let users get the information they
want/need at a glance, we're introducing release announcement
templates. The Chef release team will use these tasks to generate the
release announcements before posting them to Discourse.

+Ohai Chefs!

+# Release Highlights

+# Get the Build
+As always, you can download binaries directly from [downloads.chef.io](https://downloads.chef.io/chef-client) or by using the new `milib-install` command line utility available in ChefDK 0.19.6 or greater.
+
+```shell
+$ mixlib-install download chef -v <%= @version %> -c current
+```
+
+Alternatively, you can install Chef using one of the following command options:
+
+```shell
+# In Shell
+$ curl https://omnitruck.chef.io/install.sh | sudo bash -s -- -P chef -v <%= @version %> -c current
+
+# In Windows Powershell
+. { iwr -useb https://omnitruck.chef.io/install.ps1 } | iex; install -project chef -version <%= @version %> -channel current
+```
+
+If you want to give this version a spin in Test Kitchen, create or add the following to a `.kitchen.local.yml` file:
+
+```yaml
+provisioner:
+  product_name: chef
+  channel: current
+  product_version: <%= @version %>
+```
