SimpleUnitFrames v1.33.1 - Release

SimpleUnitFrames v1.33.1

This release ships the validated DataText enhancement track together with the first validated low-risk non-unit event coalescer rollout.

Highlights

• DataText layouts now support validated 3-slot, 5-slot, and 7-slot configurations.
• DataText LDB integration now supports per-slot display modes, tooltip fallback rendering, hover refresh, and click dispatch parity with common broker displays.
• Currencies, Reputation, Spec, and LootSpec provider paths have been hardened and validated, with parity between datatext and databar presentation.
• The low-risk coalescer pilot is included in this release:
  • shared SPELL_UPDATE_COOLDOWN + SPELL_UPDATE_CHARGES bucket
  • debounced BAG_UPDATE bucket
  • /suf coalescer and /suf coalescer reset diagnostics

Validation Summary

• DataText Step 3, Step 5, Step 5b, and Step 5c all passed in-game validation.
• Low-risk coalescer pilot validated in dungeon gameplay:
  • SPELL_UPDATE_COOLDOWN+SPELL_UPDATE_CHARGES 6002 -> 2700 (~55.0% reduction)
  • BAG_UPDATE 38 -> 21 (~44.7% reduction)
• CustomTracker bars remained correct for cooldown, charges, and bag-driven updates during validation.

User-Facing Changes

• 7-slot DataText support with outerLeft and outerRight slots
• Per-slot LDB display modes: AUTO, TEXT, ICON, ICON_TEXT
• Full-width DataText panel clamping with 40px default panel height
• Better LDB tooltip fallback and live hovered-source refresh
• Improved Spec/LootSpec display stability
• Better currency/reputation tooltip detail and databar parity

Notes

• This release includes the validated low-risk coalescer work.
• Broader coalescer expansion to additional non-unit buckets is deferred to follow-up work.

🔧 Technical Implementation

DirtyFlagManager Integration

• 4 New Helper Functions:

  • MarkFrameDirty() - Queue individual frames
  • MarkAllFramesDirty() - Batch all frames
  • MarkFramesByUnitTypeDirty() - Queue by unit type
  • GetFrameUpdatePriority() - Smart priority assignment

• 3 Modified Update Methods:

  • UpdateAllFrames() - Batched with fallback
  • UpdateFramesByUnitType() - Deferred updates
  • SetupPerformanceLib() - DirtyFlagManager init

Smart Priority System

• CRITICAL (4): Player frame - immediate visual feedback
• HIGH (3): Target/Focus frame - responsive targeting
• MEDIUM (2): Party frames - moderate batching
• LOW (1): Raid frames - aggressive batching

Event Configuration Expansion

Added 14 new events to intelligent batching pipeline:

• 13 UNIT_SPELLCAST_* events (START, STOP, CHANNEL_START, CHANNEL_STOP, EMPOWER_START, EMPOWER_UPDATE, FAILED, INTERRUPTED, DELAYED, UPDATE, INTERRUPTIBLE, NOT_INTERRUPTIBLE)
• UNIT_AURA (batch aura events)
