Heals through beacon no longer trigger the casted animation, which also seems to have stopped LoD from animating in the the air.
Light of Dawn frequently and seemingly randomly will fail to cast, and will display an "Invalid Target" error. This is a glitch, but I thought it was worth mentioning.
Word of Glory now uses the CoH graphic.
The Body and Soul run speed buff now has a new, very sparkly effect (may also effect Speed of Light).
The Holy Word mouseover glitch was fixed, but only for Holy Word Sanctuary. HW: Serenity still isn't working properly via mouseover / click cast addon.
Holy Word: Sanctuary and Holy Word: Serenity now have their own spell icons.
Feel free too add more to the list
