★ HEADLINE: NEW MODULE — Group Frames

A complete party/raid frame system has been added. ~21,150 LOC across 17 new files, positioned as a built-in alternative to Grid2/Cell. All under GroupFrames/.

Architecture (new files)

• MSUF_GF_Core.lua — factory, layout, preview, hiding (EQoL-pattern hierarchy on SecureGroupHeaderTemplate)
• MSUF_GF_DB.lua — defaults + config resolution, 3-slot health text modes, name color, role-aware visibility
• MSUF_GF_Render.lua — coalesced dirty-flag visual pipeline (multiple DB writes → 1 update per tick)
• MSUF_GF_Effects.lua — per-frame RegisterUnitEvent, range fade (Grid2 pattern), aggro/dispel/target borders, AFK/DND text, UNIT_AURA coalescing
• MSUF_GF_Auras.lua — 3-group aura display (Buffs / Debuffs / Externals), zero-alloc icon pools, externals via BIG_DEFENSIVE filter
• MSUF_GF_AuraFilter.lua — 2-tier filter engine (Tier 1: Blizzard API tokens, Tier 2: declassified spell blacklist, user-toggleable)
• MSUF_GF_AuraPreview.lua — drag-to-position mock frame, live colors, real spell icons via process-lifetime cache
• MSUF_GF_PrivateAuras.lua — 12.0.5 Private Aura anchoring + Dispel Overlay (isContainer = true), no fallback paths
• MSUF_GF_SpellIndicators.lua + MSUF_GF_SpellIndicators_Data.lua — per-spell tracker for healer HoTs (icon/square/bar/number + frame effects: tint, border, glow, pulse, name color, alpha), multi-spec
• MSUF_GF_HealerBuffs.lua + MSUF_GF_HealerBuffs_Editor.lua — per-spec spell families, compilation, aura matching, manual slot management
• MSUF_GF_CornerIndicators.lua — 5 fixed slots (TL/TR/BL/BR/C) for dispel/aggro/custom dots, full perf rewrite
• MSUF_GF_GroupNumber.lua — subgroup number (1-8) overlay, hooked into public GF API
• MSUF_GF_Masque.lua — separate Masque group from A2, registers Icon + Cooldown only (count never passed)
• MSUF_GF_EM2.lua — Edit Mode 2 integration, GF behaves like a normal EM2 unitframe (CENTER-stored offsets)
• MSUF_BossFrameBridge.lua — bridges MSUF boss1..boss5 frames into the GF Private Aura subsystem (additive only, no GF child-registration)

GF features

• Party + raid in one addon — created via SecureGroupHeaderTemplate, A/B pool system to handle zone-change header recreation
• 3-slot health text — textLeft / textCenter / textRight independently configurable
• Power-bar role visibility — show/hide power per assigned role
• Smooth fill toggle — animated bar fill, default ON
• Hide-in-client-scene — auto-hide GF in cinematics/cutscenes
• Target/aggro highlight — configurable size / draw layer / texture
• Dispel tint + glow via LibCustomGlow integration
• Dispel Overlay edge modes — Full Frame / Bottom Edge / Top Edge / Left Edge / Right Edge
• Externals defensives panel — separate slot for external CDs (e.g. Pain Suppression, Roar of Sacrifice)
• Boss-heal auras for Boss frames — highlightOwn (highlight your own healing) + hideOthers (suppress other players' heals)
• Backed by Masque with separate skin group from A2
• Mini-cc integration — frames registered in _G.MSUF_UnitFrames for party1-4 / raid1-40 (base units never registered to avoid stomping power bar)
• Preview/edit mode — drag-to-position with radio-section UX, scaled preview (1.4×–2.8×)

Group Frames Options

• New Options/MSUF_Options_GF.lua (~9k LOC) — Layout / Health & Text / Indicators / Effects tabs
• New Options/MSUF_Options_GF_Auras.lua (~3k LOC) — Buffs / Debuffs / Externals scopes

---

★ ARCHITECTURE: Code Consolidation

Three large modules were collapsed from many small files into fewer, more cohesive ones — easier to navigate, fewer file-scope local pressures, faster TOC parse.

Auras 2.0 — 14 files → 6 files

• Removed: A2_Cache, A2_Collect, A2_Colors, A2_CooldownText, A2_Filters, A2_Icons, A2_Masque, A2_Preview, A2_Public, A2_Units
• Consolidated into: MSUF_A2_Core.lua (Cache + Collect + Icons), MSUF_A2_DB.lua (DB + Colors + Filters + Public + Units)
• Kept: A2_DB, A2_Reminder, A2_Render, A2_Events, A2_EditMode

Edit Mode 2 — 16 files → 5 files

• Removed: EM2_Anchors, EM2_Compat, EM2_Elements, EM2_Grid, EM2_Init, EM2_Nudge, EM2_PopupFactory, EM2_Popup_Aura, EM2_Popup_Cast, EM2_Popup_Unit, EM2_Registry, EM2_Snap, EM2_State, EM2_Ticker, EM2_Undo
• Consolidated into: MSUF_EM2_Core.lua (Registry + State + Undo + Init), MSUF_EM2_Layout.lua (Grid + Snap + Anchors + Nudge + Ticker)
• Kept: EM2_Movers, EM2_Popups, EM2_HUD

ClassPower — 15 files → 4 files

• Removed all ClassPower/Modes/MSUF_CP_Mode_*.lua, Features/MSUF_CP_*.lua, Core/MSUF_CP_*.lua, MSUF_CP_Profiles.lua
• Consolidated into: MSUF_CP_Core.lua (Build + Layout + Presentation + Runtime + Specials), MSUF_CP_Modes.lua (all mode builders)
• Kept: MSUF_CP_Constants.lua, MSUF_CP_Controller.lua

Removed legacy modules

• Core/MSUF_Indicators.lua — replaced by MSUF_EliteIcon.lua + indicator changes in core
• Modules/MSUF_3DPortraits.lua — replaced by the rewritten MSUF_PortraitDecoration.lua

---

★ NEW: Foundation & Core Modules

Foundation/MSUF_BlizzKill.lua (NEW, 334 LOC) — Blizzard frame kill system + compat anchors + HideDefaultFrames. Tracks killed frames for re-assertion on PLAYER_ENTERING_WORLD (loading screens, flight, zone transitions). Combat-deferred RegisterStateDriver via lazy PLAYER_REGEN_ENABLED. Zero per-frame overhead. Extracted from the main backbone for maintainability.

Foundation/MSUF_Scheduler.lua (NEW, 96 LOC) — central next-frame / delayed scheduler. Replaces scattered C_Timer.After(0, ...) runtime deferrals with keyed, deduped scheduling. Secret-safe (no protected/secret API reads).

Core/MSUF_EliteIcon.lua (NEW, 136 LOC) — per-unit elite / rare / rare-elite icon overlay using nameplates-icon-elite-gold and nameplates-icon-elite-silver atlases. Supported on: Target, Focus, Target-of-Target, Boss. Per-unit DB keys: showEliteIcon, eliteIconSize, eliteIconAnchor, eliteIconOffsetX/Y, eliteIconLayer.

---

★ Performance Overhaul (Midnight 12.0)

UnitframeCore — hash-dispatch event handler

• Replaced if/elseif chain in FrameOnEvent with _UF_DISPATCH hash table (UNIT_HEALTH, UNIT_POWER_UPDATE, UNIT_POWER_FREQUENT, UNIT_MAXHEALTH, etc.)
• Lazy text-clear flags _msufHpTextCleared / _msufPowerTextCleared — skip redundant SetText("") calls

Bars — calculator-based unified health update

• New _MSUF_HealthCalcUpdate — ONE CreateUnitHealPredictionCalculator per frame, ONE UnitGetDetailedHealPrediction call delivers HP, max-HP, absorbs, heal-absorbs, incoming heals (all C-side, secret-safe)
• Eliminates per-event API call clusters; only runs on UNIT_MAXHEALTH/UNIT_ABSORB_AMOUNT_CHANGED/UNIT_HEAL_ABSORB_AMOUNT_CHANGED/UNIT_HEAL_PREDICTION/UNIT_MAXHEALTHMODIFIER (lean path on UNIT_HEALTH)
• Pure-function unit-key normalize cache — eliminates 8× GetBossIndexFromToken lookups per target click
• Settings-serial gate (_msufBarConfigGen) skips redundant overlay-color and absorb-enable resolution
• MSUF_SetBarValue / MSUF_SetBarMinMax reduced to 1-line direct C calls (no smoothing/transaction wrappers)

Auras2 Render — render-path optimizations

• Inlined DirtyAdd + ScheduleFlush (3 function calls → 0)
• Inlined AcquireIcon fast path — pool[i] hit skips function call entirely
• Per-configGen cached resolved config — eliminates ~40 table reads per aura event
• Combat-skip for preview entirely (isEditActive always false in combat)
• Aura table pool (max 64 entries) — zero Lua allocations for aura updates in steady-state raid combat
• Sort-order 0 fast path: pure cache iteration, ZERO C API calls per render
• _masqueButtonCount tracking — Masque ReSkin only on structural change

StatusIndicators — AFK/DND cache

• New _MSUF_GetCachedAwayStatus with bit flags + invalidation API
• Cached _MSUF_AwayHasBit / _MSUF_AwaySetBit — replaces per-frame UnitIsAFK/UnitIsDND polling

RangeFade — array-cached frame refs

• New _pollFrames array (replaces map-based iteration), _pollUnits, _pollConfKey, _pollCount for tight inner loop
• 175 added / 47 removed LOC

EventBus — simplified dispatch

• Removed _DispatchSafe/_DispatchFast split; removed :SetSafeCalls
• Direct dispatch via simplified Compact / MaybeUnregister helpers
• 285 LOC removed, 74 added — net -211

Modules.lua — pcall removed from registration

• SafeCall no longer wraps in pcall; runs callback directly
• Replaces former hooksecurefunc for RoundedUF init with explicit _G.MSUF_RoundedUF_OnModulesApplied notify

---

Bars (Core/MSUF_Bars.lua)

• NEW Bar Mode: gradient — HP-derived gradient mode added alongside dark / class / unified
• Gradient direction pad — independent gradientDirLeft / gradientDirRight / gradientDirUp / gradientDirDown flags (replaces single gradientDirection string; auto-migrates on first load)
• Gradient strength slider — gradientStrength 0–1 (default 0.45)
• Power bar gradient — powerGradientEnabled independent of HP gradient
• Scope-aware bar border thickness — new MSUF_NormalizeBarBorderScope / MSUF_GetScopedBarBorderThicknessDB / per-scope cache (MSUF_BarBorderCache.byScope)
• hlOverride flag — additional override key alongside hpPowerTextOverride for absorb display/anchor/opacity resolution
• Dark-tint helper ns.Bars._DarkTint(g, r, gg, b) and `ns.Bars....

4.0b13

Midnight Simple Unit Frames 4.0 — Beta 13 Changelog

Beta 13 is a focused bugfix release for absorb handling and Group Frame Edit Mode.

Fixes

• Fixed absorb and heal-absorb display settings not correctly respecting per-frame overrides.
• Improved absorb/heal-absorb bar updates by using the shared health calculation path and safer fallback APIs.
• Fixed absorb and heal-absorb bars not clearing properly when no absorb value is active.
• Cleaned up absorb overlay colors and removed stale legacy color key conflicts.

4.0b12

MSUF 4.0 Beta 12 — Bugfixes

Fixed

• PI tracking removed — Power Infusion entries cleared from spell-indicator data (SecretSpellIDs, icon table, TrackableAuras, SpecDefaults).
• Phased players — UNIT_PHASE now triggers a full frame refresh instead of only updating the phase icon. Names and frame state stay in sync when players phase in/out.
• Roster reshuffle leftovers — When a SecureGroupHeader slot gets reassigned to a different unit, the new occupant no longer inherits the previous player's debuff stripe, dispel border, displayed-aura cache, or aggro state.
• Debuff stripe stuck on — Removed debuffs that weren't currently visible as icons (over icon limit, or filtered into the stripe-only path) now correctly clear the stripe via the dispatchAura remove-only fast path. Disabling the stripe feature in options now also hides the visual immediately.
• Cooldown swipe missing on debuffs — Aura icons now call SetUseAuraDisplayTime(true) alongside SetCooldownFromDurationObject, which is required in 12.0 for the C-side swipe animation on non-self auras. Diff-gated, no extra cost on steady state.
• Private Aura position / layer — X/Y offset sliders and Layer dropdown now apply live. Cheap reposition path avoids tearing down AddPrivateAuraAnchor registrations when only the container offset changed.
• Fixed Target of Target anchoring

MSUF Beta 11 — Changelog

3.70

Full Changelog: 3.66...3.70
MidnightSimpleUnitFrames 3.70

Big interrupt-indicator pass. The feature was broken on 12.0.5 — colors didn't wire up, non-interruptible casts still showed green, and several paths tainted. 3.70 fixes and refactors the whole module, adds a new border-tint style, and hardens the surrounding castbar pipeline.

Fixed

• Interrupt Ready Indicator wasn't actually using the Colors-menu swatches — "Ready color" / "Not ready color" under "Interrupt Ready Indicator" were ignored. Now correctly read on every paint.
• Non-interruptible casts (boss spells with permanent shields, immune buffs) showed a green/red indicator anyway. Now fully invisible — the indicator only appears on actual interruptible casts.
• Brief green/red flash at the start of shielded boss casts — eliminated via deferred first paint.
• GCD bar / castbar pipeline would taint and break on hasted specs (12.0.5 marks haste returns as secret values; arithmetic on them crashes the addon). Pipeline reworked end-to-end to never touch secret values from Lua — they now flow only through the C-side helpers (SetAlphaFromBoolean, EvaluateColorFromBoolean).
• Three Focus-Kick-Icon color paths that would have tainted as soon as the indicator started returning real data — rewritten to be secret-safe.

New

• Castbar border tint as an alternative to the colored box — tints the existing castbar outline green when your interrupt is ready, red when on cooldown, fully transparent on non-interruptible casts. Switch via the new Style dropdown in Section 7.
• Auto-size to castbar height checkbox (on by default). Manual size slider expanded to 8–32 px.
• Inline hint in Section 7 pointing to where the colors are configured.

3.66

Full Changelog: 3.65...3.66

Fixed issue with castbars not working
