-**Adjusted behavior of `relative_time` and `today_at`**
+Thanks, [@depoll], [@ehendrix23], [@petro31], and [@rokam], for these amazing
+additions down below! ❤️

+### Adjusted behavior of `relative_time` and `today_at` <!-- omit in toc -->
 
 [@Petro31] adjust the behavior for template entities using the `relative_time`
-and `today_at` template function, to now update their state once a minute. Nice!

-**New `is_hidden_entity` function**
+### New `is_hidden_entity` function <!-- omit in toc -->
 
 The brand new `is_hidden_entity` function was added by [@depoll], which can tell
 if a given entity has been marked "hidden" or not. This function also works
 as a test. Cool!

-**New `areas` function**
+### New `areas` function <!-- omit in toc -->
 
 Talking about areas, [@rokam] added an `areas` function, which returns a list
 of all areas you have!

+### Added `break` and `continue` for use in for loops <!-- omit in toc -->
 
 [@depoll] added support for `break` and `continue` in for loops, which allows
 short-circuiting those loops, allowing you to make them more efficient.
