Changelog

[1.0] - 28/01/2026

Initial release of LibEventBus-1.0.

• Added event bus creation via lib:NewBus(name, safe) and a global singleton via lib:GetGlobalBus().
• Event registration and management:
  • RegisterEvent(event, fn) returns an unregister function.
  • UnregisterEvent(event, fn) and UnregisterAll(event) for handler cleanup.
  • RegisterEventOnce(event, fn) for one-shot handlers.
  • IsRegistered(event) to check active handlers.
  • TriggerEvent(event, ...) to dispatch custom events.
• Safe dispatch with error handling using safeCall; optional fast path when safe is false.
• Native WoW event integration via a backing Frame (CreateFrame("Frame")) with lazy registration and automatic unregistration when no handlers remain.
• Handler list compaction and duplicate prevention to reduce allocations and keep dispatch efficient.
• Hooking support:
  • HookSecureFunc(frameOrGlobalName, funcName?, handler) for secure function hooks.
  • HookScript(frame, scriptName, handler) for frame script hooks (tracks hooks per-frame to avoid duplicates).
• Requirements: relies on LibStub; library registered as LibEventBus-1.0 (minor version 1).

Notes

• Versioning follows LibStub major/minor, with this being the first minor release.
• API is designed for safety-first usage by default (safe = true).
