Overview

We can iterate over site.posts and keep track of the current year. When the year changes, we’ll output the year as a title and then carry on outputting the post details.

...
{% for post in site.posts %}
  {% capture current_year %}{{ post.date | date: "%Y" }}{% endcapture %}
  {% if current_year != previous_year %}
    {% unless forloop.first %}
      </ul>
    {% endunless %}
    <h2>{{ current_year }}</h2>
    <ul>
    {% assign previous_year = current_year %}
  {% endif %}
  <li><a href="{{ post.url }}">{{ post.title }}</a></li>

  {% if forloop.last %}
    </ul>
  {% endif %}
{% endfor %}
