New Features

Group Frames (entirely new module — 23,000+ lines)

• Full party, raid, and mythic raid unit frames built from scratch as a first-class MSUF system
• Each frame shows HP bar, power bar, name text, role/leader icons, and status icons

• Healer Buffs — dedicated healer buff tracker with a built-in in-game editor
• GF Effects — HP gradient, missing HP overlay, absorb bar, and glow effects per group frame
• Group Number — optional group number display per frame
• Boss Frame Bridge — MSUF group frame system bridges Blizzard boss frames for consistent styling
• Edit Mode — full drag/drop placement and per-frame popup configuration in Edit Mode
• Masque support — group frame aura icons are Masque-skinnable
• Dedicated Options — two new options panels: Group Frames and Group Frame Auras

Blizzard Native Aura Renderer (Group Frames)

• Group frames use Blizzard's C-side native aura container by default
• Aura rendering happens at engine level — zero Lua overhead per aura update in raids
• Configurable types: Buffs, Debuffs, Dispellable auras, Externals, Private Auras — all independently toggleable
• Configurable: icon size, cooldown text, organization type, dispel mode, container anchor and offset
• Can be switched to MSUF custom renderer per group if desired
• This is the performance-with-Blizzard-auras change — in large raids, aura updates that previously fired Lua filter/render loops now pass through Blizzard's optimized C path entirely

Dispel Glow Effect (Unit Frames)

• New animated glow overlay on the dispel highlight border, powered by the bundled LibCustomGlow-1.0
• Three glow styles selectable: Pixel, AutoCast, Proc
• Configurable: line count, animation frequency, thickness
• Color follows the dispel border color automatically
• Test mode checkbox for previewing in the options menu

Elite / Rare Icon

• New icon overlay for Target, Focus, Target-of-Target, and Boss frames
• Gold icon for Elite and World Boss units; silver for Rare and Rare-Elite
• Configurable: size, anchor (TL/TR/BL/BR), X/Y offset, draw layer (1–10)

HP Bar Gradient Mode

• New Gradient bar color mode alongside the existing Dark, Class Color, and Unified modes
• HP bar shifts red → yellow → green based on current health
• Implemented via C_CurveUtil.CreateColorCurve — runs entirely C-side, fully secret-safe
• No Lua arithmetic on HP values

HP Bar Alpha Layer

• New HP Bar option in the per-unit alpha layer dropdown (previously only Foreground / Background)
• Separate in-combat and out-of-combat alpha sliders for the HP bar specifically
• Allows the HP bar to fade independently from the frame background and text

Preserve HP Color

• New "Preserve HP Color" checkbox in the alpha settings
• HP bar retains its class color / gradient even when transparent
• Uses the bundled Better Blizzard bar texture which supports color bleed-through at sub-1.0 alpha
• Works in all alpha layer modes

New HP Text Modes — Full Set

• 7 new HP text display modes added to the bars options dropdown:
  • Percent / Current — percent first, then current value
  • Current / Max — slash-separated, no percent
  • Percent / Max — percent first, then max
  • Current / Max / Percent — three-part display
  • Percent / Current / Max — percent-first three-part
  • Max / Percent — max then percent
  • Percent / Max / Current — full reverse
• New NormalizeHpTextMode() migration function maps old profile key names to new ones
• Missing HP value display using UnitHealthMissing for a "−deficit" style

Per-Debuff-Type Dispel Colors (Colors Menu)

• New Dispel collapsible section in the Colors menu
• Color mode dropdown: Single (one color for all dispels) or Per debuff type
• Individually configurable colors for: Magic, Curse, Disease, Poison, Bleed
• Dispel color is shared between the highlight border on unit frames and the dispel overlay on group frames

Per-Unit Highlight Override

• Each unit frame can now have fully independent highlight and border settings
• New hlOverride flag per unit DB entry — when enabled, that unit's highlight reads from its own config instead of the shared global settings
• Enables e.g. giving the target frame a unique dispel color while player stays on shared settings
• Group frames note in the menu clarifies which highlights apply to GF

Portrait Fade on Range

• New "Also Fade Portrait" toggle in Misc → Range Fade
• Portrait textures (2D and 3D) now participate in range fade alongside the rest of the frame

HP Smooth Interpolation (Native)

• Health bar smooth fill now uses Enum.StatusBarInterpolation.ExponentialEaseOut where available
• Hands interpolation to the C-side status bar engine — zero per-frame Lua cost

New Bar Texture: Better Blizzard

• New bundled bar texture registered as "Better Blizzard" in LibSharedMedia
• Used internally by the Preserve HP Color feature; also selectable as a regular bar texture

New Gradient Textures

• 4 new overlay textures: horizontal gradient, horizontal reversed, vertical gradient, vertical reversed

New Icon Sets — 11 Styles

• Role/leader icons now ship in 11 visual styles: Classic, DarkEmboss, Diamonds, Dots, GlassPanels, GlossyOrbs, Midnight, NeonOutline, RingSymbols, Shapes, Squares

• Fully backwards compatible — MSUF2: profiles continue to import without issues
• Import/Export now includes Group Frame settings, all new alpha keys, elite icon settings, per-unit highlight overrides

Improved Existing Features

Status Indicators — AFK / DND Tracking Rewritten

• AFK and DND flag tracking replaced with a GUID-based bitfield cache
• MSUF_AWAY_AFK = 1, MSUF_AWAY_DND = 2 — stored as bitfield per GUID (or unit token as fallback)
• Separate cache tables: _msufAwayFlagsByGUID / _msufAwayCheckedByGUID (prefer GUID) and _msufAwayFlagsByUnit / _msufAwayCheckedByUnit (fallback for ungrouped units)
• PLAYER_FLAGS_CHANGED event now drives per-unit AFK/DND invalidation — zero polling, event-driven only
• New public API: MSUF_GetCachedAwayStatus, MSUF_InvalidateAwayStatus, MSUF_ClearAwayStatusCache
• Mouseover tooltips now call MSUF_GetCachedAwayStatus instead of direct UnitIsAFK/UnitIsDND
• AFK/DND suppression inside instances during combat preserved (_MSUF_AwaySuppressedNow)

Status Indicators — Icon Layer System

• New _MSUF_ApplyIconLayer helper applies per-indicator draw layer via the layout system
• Combat, Rested, and Rez icons each have independent layer settings
• MSUF_ApplyStatusTextLayout now exported as a global for external module use
• Symbol texture cache keyed on symbolKey + useMidnight flag — avoids repeat path-building

Auras2 Engine — Consolidation and Optimization

• 14 source files consolidated into 4 (A2_Core, AuraNative, A2_Render, A2_Reminder)
• Selective field copy: only the fields actually consumed by cache/filter/render are copied per aura — saves ~50% work vs. a generic for k,v in next over full C API aura tables
• Lightweight update copy for updatedAuraInstanceIDs path: only 5 mutable fields written (duration, expirationTime, applications, isRaid, isBossAura) — saves 8 table writes per update across ~31,000 calls/session in raid combat
• MSUF_AuraNative extracted as a shared abstraction for the CUSTOM and BLIZZARD renderer paths, used by both unit frames and group frames
• Buff reminder lookups now attempt direct C_UnitAuras.GetAuraDataByAuraInstanceID first, with cache fallback — more reliable on fresh login

HP Bar Color System

• File-scope cached bar mode variables (_ufcBarMode, _ufcBarModeIsGradient, _ufcDarkR/G/B, etc.) set once per settings change in RefreshSettingsCache
• Eliminates per-update table lookups in RefreshHealthBarColorFast hot path
• New MSUF_UFCore_GradientCurve global exposes the C-side color curve to MSUF_Bars.HealthCalcUpdate

Health Update — Calculator-Based

• CreateUnitHealPredictionCalculator per frame instead of UnitGetDetailedHealPrediction
• Single C-side call returns current health + absorbs + heal-absorbs + incoming heals simultaneously
• SetValue called directly without Lua-side secret-value guards — WoW 12.0 handles secrets C-side

Unit Normalization Cache

• NormalizeUnit() result now cached in a file-scope table
• Eliminates redundant GetBossIndexFromToken lookups that previously fired 8× per target click

Bars — Power Bar Scoping

• smoothFill for power bar now stored per-unit (player/target/focus/boss) rather than globally shared
• New helpers: MSUF_Bars_GetPowerBarScopeUnitKey, MSUF_Bars_GetSmoothPowerForCurrentScope, MSUF_Bars_SetSmoothPowerForCurrentScope
• HP/Power text modes are now independently scopeable from bar/highlight overrides via hlOverride

Bars — Colors Menu: Gradient in Bar Mode Dropdown

• Gradient added as fourth option in the bar color mode dropdown (alongside Dark, Class Color, Unified)
• Switching to gradient disables legacy darkMode / useClassColors flags automatically

Scheduler — Deduped Next-Frame Dispatch

• New MSUF_Scheduler replaces scattered C_Timer.After(0, ...) deferrals throughout the codebase
• Keyed scheduling: scheduling the same key twice in one frame yields exactly one callback
• Ring-buffer queue; OnUpdate registered only while work is pending, removed immediately after flush

BlizzKill — Extracted and Hardened

• Blizzard frame suppression logic extracted from the main file into MSUF_BlizzKill.lua
• Zero per-frame overhead: no OnUpdate, no polling
• Combat-deferred RegisterStateDriver via lazy PLAYER_REGEN_ENABLED listener
• Frames re-asserted hidden on PLAYER_ENTERING_WORLD (loading screens, zone transitions, flight)

Portraits — Unified 2D/3D System

• MSUF_3DPortraits.lua merged into MSUF_Portraits.lua — "Unified 2D/3D/Class portrait system"
• EnsureModel() creates the PlayerModel on demand — no separate preload file needed
• SafeCall helper prevents nil errors on partially constructed frames
• On PLAYER_TARGET_CHANGED: if portrait mode is OFF for all units, all portrait work is skipped entirely (no InvalidateByKey, no SyncUnitSafe, no HideAllDecor)

Range Fade — Improvements

• Range fade strength now a configurable 0–60% slider (previously hardcoded)
• New FRIENDLY_SPELLS table per class for non-party friendly range detection, covering all specs: Druid, Evoker, Hunter, Mage, Monk, Paladin, Priest, Rogue, Shaman, Warlock, Warrior
• Portrait fade toggle added as separate option from frame fade
• Improved runtime API: MSUF_RangeFade_EvaluateActive / MSUF_RangeFade_ApplyCurrent and their fallback-frame equivalents

Interrupt Indicator

• _RefreshRawNotInterruptible re-queries UnitCastingInfo/UnitChannelInfo live when no cached value is present; keeps both _msufApiNotInterruptibleRaw (target/focus) and MSUF_apiNotInterruptibleRaw (boss) in sync
• New _CastAllowsKickIndicator guard added to all three show paths — prevents the indicator firing on spells the castbar has confirmed as uninterruptible

Edit Mode — Consolidated

• 18 source files consolidated into 5 (EM2_Core, EM2_Layout, EM2_HUD, EM2_Movers, EM2_Popups)
• Registry, State, Undo, Snap, Grid, Anchors, Init all merged; element registration API documented inline

Class Power — Consolidated

• 15 source files consolidated into 3 (MSUF_CP_Core, MSUF_CP_Modes, MSUF_CP_Controller)
• New reload prompt popup when enabling or disabling class resources

Colors — Bar Mode Dropdown

• Bar color mode dropdown now shows all four modes: Dark Mode, Class Color Mode, Unified Color Mode, Color Gradient
• Switching modes correctly migrates legacy darkMode / useClassColors flags

Colors — Dispel Section Revamped

• "Dispel" is now its own collapsible section in the Colors menu
• Hint text clarifies that the dispel color is shared between the UF highlight border and the GF dispel overlay
• Single-color mode and per-debuff-type mode selectable via dropdown
• Per-type colors (Magic, Curse, Disease, Poison, Bleed) each have a color swatch with picker

Bars Options — Highlight Section Refactored

• MakeOutlineRow helper consolidates Aggro, Dispel, Purge, and Boss Target row creation
• Each outline row has an on/off dropdown and a test-mode checkbox
• Dispel outline now has a preview dropdown (per debuff type) — visible difference only with "Per debuff type" color mode
• Dispel glow sub-section (style, lines, frequency, thickness) collapses when glow is disabled

Fonts Options — Group Frame Scope

• Font scope tabs now include Party and Raid (Raid scope also applies to Mythic Raid)
• Per-scope fontOverride stored in gf_party / gf_raid / gf_mythicraid DB keys independently

Castbars Options — Disabled State

• New SetCastbarOptionEnabled helper applies enable/disable state to all control types (checkboxes, dropdowns, sliders, font strings) with proper alpha dimming

Gameplay Options — Disabled State

• Option controls dim to 0.35 alpha and disable mouse when their feature is off
• SetGameplayControlEnabled applies consistently across buttons, sliders, dropdowns, checkboxes, and their sub-elements

Colors Options — Accordion Behavior

• Opening a section auto-collapses the previously open section (radio accordion)

Portraits Options — Smart Accordion

• Portraits panel upgraded with radio accordion behavior, section state memory, and auto-open to last used section

Search Registration

• Portraits panel registered with MSUF_Search_RegisterRoots — searchable by "portraits", "portrait type", "shape", "border", "background"

Misc Menu — Status Indicators Removed

• "Status Indicators" section (AFK/DND/Dead/Ghost toggles) removed from the Misc menu — now 4 sections
• The toggles are accessible in the per-unit Status Indicator settings

Slash Menu

• Navigation header open/close state saved per-session in MSUF_GlobalDB.global.slashMenu.navHeaders
• Alpha build detection: shows a Discord report prompt for pre-release builds
• Theme refresh: new background, edge, accent (cyan), danger (red), success (green), and card colors

Font Aliases for Migration

• Legacy shortnames mapped to full names on profile import: FRIZQT, ARIALN, MORPHEUS, SKURRI, "Friz Quadrata (default)" → their proper display names

Profile Codec — MSUF3

• CBOR-first deserialization with decompression fallback
• Improved base64 padding normalization (handles unpadded strings correctly)
• Profile payload wrapped in a versioned envelope (addon = "MSUF", fmt = 2)

Default Settings

• Default startup scaling now off (disableScaling = true) — users opt in explicitly
• UIScale = { Enabled = false, Scale = 1.0 } added as a top-level default
• All alpha keys now have explicit defaults instead of nil fallbacks: alphaSync, alphaExcludeTextPortrait, alphaLayerMode, alphaHPInCombat, alphaHPOutOfCombat, alphaPreserveHPColor
• Group Frame DB defaults seeded with Blizzard renderer and sensible aura type toggles on first run
