Notes

• UnitDebuff and other UnitAura-based queries may not be accurate immediately after casting a spells that applies an aura to its target.

History

• Patch 1.9 introduced the removable argument.
• Patch 2.0 extended the maximum number of debuffs to 40 (from 16).
• Patch 2.0 introduced name and rank return values.
• Patch 2.1 introduced duration and timeLeft return values.
• Patch 3.0 changes this into an alias of UnitAura; durations are now available for all debuffs.
• Patch 3.1 changed "isMine" to "unitCaster". It is now possible for addons to retrieve the unitId that cast the buff/debuff.
