-Removal of ``Embed.Empty``
----------------------------
+Embed Changes
+--------------
 
 Originally, embeds used a special sentinel to denote emptiness or remove an attribute from display. The ``Embed.Empty`` sentinel was made when Discord's embed design was in a nebulous state of flux. Since then, the embed design has stabilised and thus the sentinel is seen as legacy.
 
 Therefore, ``Embed.Empty`` has been removed in favour of ``None``.
 
+Additionally, ``Embed.__eq__`` has been implemented thus embeds becoming unhashable (e.g. using them in sets or dict keys).
