## 📋 Version History---### ⚡ v4.3.0 — Current ReleaseStability Fix- Fixed <code>ReActorFaceBoost</code> node — correctly configured as settings-only node (no image input)- Removed incorrect image connection to FaceBoost- FACE_BOOST output now properly feeds into ReActorFaceSwap enhancement slot---### 🔧 v4.2.0Compatibility Fix- Fixed <code>interpolation</code> value: <code>'lanczos'</code> → <code>'Lanczos'</code> (case-sensitive ComfyUI requirement)- Replaced unavailable upscale model with <code>8x_NMKD-Faces_160000_G.pth</code>- Switched to face-optimized 8x upscaler for superior portrait results---### 🔗 v4.1.0Pipeline Architecture Fix- Fixed critical type mismatch: <code>FACE_BOOST</code> output was incorrectly routed to <code>ImageUpscaleWithModel</code> (expects <code>IMAGE</code>)- Corrected FaceBoost role: now feeds as enhancement input to ReActorFaceSwap, not post-processor- Fixed ESRGAN upscale input to receive <code>SWAPPED_IMAGE</code> directly from ReActorFaceSwap---### 🚀 v4.0.0 — Initial ReleaseFull Pipeline Build- 18-node professional workflow- Dual restoration: GFPGAN (inline) + ReActorFaceBoost (enhancement pass)- 3-stage source preparation: 512px → 1024px- 2048px target preparation for maximum detail preservation- 8x ESRGAN face-optimized upscaling- Dual output: HD 1536px + 4K 4096px simultaneously- 6 color-coded node groups- Full in-workflow documentation (Guide + Requirements + Pro Tips)---### 🗑️ Deprecated (from base workflow)| What | Why Removed ||---|---|| <code>center</code> crop on source | Was cutting face edges || <code>768px</code> source optimization | Replaced with <code>1024px</code> || <code>codeformer_weight: 0.5</code> | Raised to <code>0.75</code> for sharper results || Inconsistent <code>1316×1365</code> output | Replaced with clean <code>4096×4096</code> |
