- Improved compatibility when installed alongside other RuneFist and Portals products.
- Added authoritative package-level quick starts in English, Simplified Chinese, Korean, Brazilian Portuguese, and Spanish for this exact download variant.
- Added a product-specific offline HTML guide with installation choices, exact tested dependencies, troubleshooting, five-language quick starts, support requirements, and source-license guidance.
- Separated mutually exclusive resource providers and gameplay integrations into clearly labeled copy-one install options, preventing competing configurations from loading together.
- Rebuilt the ItemsAdder integration as a single ItemsAdder 4 content pack with portable folder casing and verified model, texture, armor, and sound references.
- Reworked the installation instructions so ItemsAdder no longer requires manually splitting files into legacy folders.
- Assigned a stable, unique ItemsAdder boss-bar glyph and aligned its MythicMobs display reference.
- Namespaced shared MythicMobs helper IDs and repaired stale skill/VFX references so the catalog can coexist without registry overwrites.
- Removed invalid legacy skill references and updated configuration compatibility where applicable.
- Package contents remain specific to the boss-arena tier; no Ultimate-only sound or VFX assets were added.
