-- Add datetime_today template method ([@Petro31] - [#57435])

-- Add average template function and filter ([@Petro31] - [#57727])
+For some of our more advanced users, this release has some helpful template
+improvements included as well!
+
+Let's start with the new `today_at` filter/function that [@Petro31] added. It
+allows you to quickly get a DateTime at a certain time of today. This can be
+really helpful if you need to compare against another DateTime. For example:
+
+{% raw %}
+
+```yaml
+# Is the current time past 10:15?
+{{ now() > today_at("10:15") }} 
+```
+
+{% endraw %}
+
+Next up is [@raman325], who added the `area_entities` and `area_devices` filter
+and function that allows you to get all devices or entities that are in an area.
+The methods return a list, which you can loop on.
+
+{% raw %}
+
+```yaml
+{{ area_entities('Living Room') }}  # ['light.ceiling', 'media_player.tv', ...]
+```
+
+{% endraw %}
+
+Lastly, [@Petro31] added another one: the `average` filter and function. It does
+what you think it does... It calculates the average of a list of items you pass
+to it.
+
+{% raw %}
+
+```yaml
+{{ [1, 2, 3, 4, 5] | average }} # Result: 3
+```
+
+{% endraw %}
