+## 3.8.5 — 2026-11-06 — UI polish and initialization cleanup
+
+- Replace the theme checkboxes with one **UI:** dropdown below Search: Default, Darkened or Golden, preserving existing choices.
+- Add a version button beside Defaults in Advanced Options, opening a copyable Gitea project link.
+- Match equipped-item comparison backgrounds to the source tooltip in Darkened UI.
+- Preserve native mail, quest-log and NPC quest/gossip parchment colors and torn edges in both themes, including empty quest-log artwork. Restore Golden UI's darker NPC title strip.
+- Keep item-rarity borders and formatted Golden titles consistent when windows update or are recolored again.
+- Consolidate deferred initialization, batch duplicate delayed recolors and bound the texture-classification cache while preserving frame exclusions.
+
 ## 3.8.4 — 2026-11-06 — Action-bar proc highlights
 
 - Add **Proc & Reactive Spell Highlights** (Action Bar, off): event-driven pale light-blue glows for supported spells and macros, with native pulsing animation where available. Central proc alerts remain with dedicated addons such as Proc Doc.

 > **Upgrading to 3.7:** the modules of the separate *ShaguTweaks Extras ClassicAPI* addon are now built into ShaguTweaks. **Disable or delete `ShaguTweaks-extras`** after updating, otherwise its older copies replace the built-in ones. Your on/off settings carry over. Raid Frames, Bag Item Click, Bag Search Bar and Auction Alt-Buy were not merged. See [Docs/EXTRAS_MERGE.md](Docs/EXTRAS_MERGE.md) for where each module went and why some were left out. See the [migration guide](Docs/EXTRAS_MERGE.md#removed-later) for removed modules.

 ### Interface
 
-- Darkened UI *(off)*
-- Golden UI *(off)*: gold borders, tooltips and dialogs like the WoW Forever client. Darkened UI and Golden UI also recolor the borders of ShaguDPS, Bagshui, Outfitter, SoulstoneTracker, OctoBus, RollFor and VCB, and of addon minimap buttons; Golden UI retains the default text colors. TrinketMenu keeps its own styling in every UI mode.
+- **UI:** dropdown below the Advanced Options search bar, with **Default**, **Darkened** and **Golden** (Default initially). Select one mode and press Okay to apply/reload. Existing theme selections carry over; old saves with both enabled retain Darkened priority. Both themed modes recolor supported addon borders and minimap buttons. Golden uses gold borders, tooltips and dialogs like WoW Forever while retaining default text colors. TrinketMenu keeps its own styling.
 
 Golden and Darkened UI keep the original NPC quest/gossip parchment, including its torn edges, while styling the outer frame. No stationery overlay is used on those panels.
