Update v1.8.4 release notes

"Raiding and fighting. This is the life."
– Kynerak Gravewalker, Chieftain of House Ærthegn

Update v1.8.4 has been recently released in all platforms, bringing the Angels of Caliban expansion crates to the Shop and a few other novelties:
● A new Cultist archtype has been added to certain cards, clarifying which ones interact with effects related to Cultists.
● The Eightfold Brand card has received a minor change. It now creates a Cultist in your hand, rather than a 'Signus Cultist'
● Progress completing challenges is now saved throughout battle, so it will get counted even if the match ends due to a disconnection.
● Caliban has been added to the list of expansion available in the search boxes.
● There have been numerous improvements to the German translation.
● Several other minor bug fixes.
