Petting 4.2.3-beta.2 (Forge 1.20.1)

This version is a backport of the latest features from NeoForge 1.21.1 to Forge 1.20.1!

Major Changes and Backported Features:

• Registry System Overhaul: Migrated from NeoForge's \DeferredHolder\ and \DeferredItem\ back to Forge's \RegistryObject.
• Networking Modernization: Migrated the \Payload\ based networking to Forge's \SimpleChannel\ and \PacketDistributor.
• Capability System Reset: Downgraded the NeoForge Attachment system back to the classic Forge \Capability\ system for pet inventories.
• Attributes System: Adjusted UUID-based \AttributeModifier\ system to match the legacy 1.20.1 signature. Reverted \Attribute\ registry logic to use Supplier-based definitions.
• Config & GUI Enhancements: Ported the \ConfigScreenFactory\ implementation to use the older \ConfigScreenHandler. Also resolved numerous screen rendering changes, falling back to 1.20.1 compatible enderBackground\ and GUI drawing methods.
• Event Bus Adjustments: Re-mapped \LivingEvent, \LivingDamageEvent, and Menu Screen Registration events to their appropriate 1.20.1 equivalents.
• Controls & Keybindings Overhaul: Replaced brittle manual thread polling with native Forge \RegisterKeyMappingsEvent\ and \InputEvent.Key\ for responsive and reliable Pet Settings (P) activation.
• Settings UI & Network Synchronization: Resolved missing Network Packet registrations that caused the Settings UI to silently fail, fully restoring bidirectional UI-to-Server syncing.
• Translation Keys & Localization: Performed a massive extraction and injection of missing localization strings, tooltips, and dynamic action mapping states into en_us.json for proper English formatting.
