Stored Program Controls — API Changelog

API Version 1.1.5 (April 17, 2026)

Guide Book API (Patchouli Integration)

• SpcGuideBookRegistry: Thread-safe static registry for addon guide book content. Addons register categories and entries during mod setup; content is frozen alongside other registries in FMLCommonSetupEvent.
• SpcBookCategory: Record declaring a guide book category with categoryId (namespaced), name, description, icon, sortnum, and optional parent for subcategories.
• SpcBookEntry: Record declaring a guide book entry with entryId (namespaced), name, icon, category reference, sortnum, priority flag, and a list of SpcBookPage objects.
• SpcBookPage: Immutable page data with factory methods for common Patchouli page types: text(), spotlight(), crafting(), image(), entity(), and custom() for any Patchouli type.
• Multi-addon safety: Duplicate category/entry IDs are handled gracefully — first registration wins, subsequent duplicates log a warning and are skipped. No crash on conflicts.
• Unknown category references are logged as warnings at freeze time but do not prevent entries from being included.
• Content is served via an in-memory resource pack injected through AddPackFindersEvent. Addon mods do not need to ship Patchouli JSON files manually.
• New API package: com.hypernova.spc.api.book (4 classes).
• API jar: storedprogramcontrols-1.1.5-api.jar (42+ classes, 13 packages).
