<p class="tag tag--new-features"><strong>New features</strong></p>
<ul>
<li>Feature 1</li>
<li>Feature 2</li>
<li>Feature 3</li>
</ul>

To create the template that I used to show how a release post would look like:
For the content, each element is a bullet in a bulleted list.

To separate the content in categories I made a p tag and has a <strong> tag inside.
the each p tag has 2 classes:
the ‘tag’ which is the same for each type. And then a class that represents the specific category. So, for example, I have:
class=”tag tag–new-features”

I used the following classes:
tag–new-features
tag–improvements
tag–fixes

If you need more categories, we can add them, but I will need to add some CSS to color-code them so they have a distinct look.
