BFA WowCombatLog.txt Changes

Good morning,

I’m working on a project where I’m using the raw WowCombatLog.txt, and was pretty far along prior to the BFA pre-patch, I’ve noted that there are additional fields in some events such as SWING_ and SPELL_DAMAGE (etc). I have been looking all over for an explanation of what the new fields are in the middle of the lines.

Can anyone please help me with a description of these new fields?

Thank you in advance for your assistance.
