Yes, I know wrong forum, but this will reach the most people. And half the playerbase is waiting for this.
From Blizzard forums:
Fixed an issue where Blood Lance could deal far more damage than intended under certain circumstances.
Fixed an issue where Warlock’s Eviscerate Fragment could deal unintended damaged when paired with Paingorger’s Gauntlets.
Fixed an issue where Ball Lightning was not a Core Skill.
Developer’s Note: The tooltip for Ball Lightning will continue to not show the tag, but it will function as a core skill. The tooltip will be updated with our next client patch.
Stability improvements.
