Nem: Healer Alerts

## v12.0.22 — May 2, 2026 ### Mistweaver Monk — Major Performance Improvements Removed background polling entirely from the Mistweaver module. The addon no longer runs a repeating check every 0.25 seconds — every detection now reacts to in-game events as they happen. In practical terms: zero idle CPU cost between pulls, and noticeably less CPU impact during heavy combat. **Soothing Mist changes:** - The addon now detects your Soothing Mist channel target the moment you start casting, via WoW's spell cast events. Mouseover macro target switches are handled correctly — if you retarget mid-channel, the old target is released and the new one is picked up after a brief delay. - The Enveloping Mist alert clears the instant EM lands on your target, rather than waiting for the next evaluation cycle. **Raid frame glows:** - Raid frame glow updates no longer run on a timer. Buff changes trigger a deferred update that fires on the next game frame instead. Multiple buff changes on the same frame within one render frame are collapsed into a single update pass — same visual result, less CPU work. **Other removals:** - Removed a background Renewing Mist tracking system that was carrying dead code since v12.0.20 and doing work with no visible effect. **Measured CPU results (20-person raid):** | | Before | After | |---|---|---| | Average CPU | 3.48% | **0.40%** | | Encounter CPU | 6.07% | **5.33%** | | Peak CPU | 21.45% | **13.92%** | ### New: `/nha env` command Snapshot diagnostic for the Enveloping Mist alert. If the alert is misbehaving, run this command and check the output — it shows your active SM target, whether the EM check passed, and current alert state. ---
