MixinTale

Breaking changes

• Complete rewrite of MixinTale (v1 was a minimal, experimental prototype and was not production-ready).
• Patch discovery is now index-driven (via generated mixintale.index.json) instead of relying on fragile runtime behavior.
• Runtime weaving strategy changed: handlers are now copied into the target class, removing the need for target classes to reference patch classes at runtime.
• Updated/standardized annotation contract and matching rules (method descriptors, internal names, callsite matching).

Added

• Full patch action set:
  • @Prefix, @Postfix, @Replace
  • Callsite patching: @RedirectCall, @WrapCall
  • Parameter roles: @This, @Arg, @Result
  • Operation<R> for safe “call original” behavior in wrap handlers
• Annotation processor that generates a per-mod patch index (mixintale.index.json).
• Deterministic patch ordering (stable application rules + priority support).
• Stronger validation and better error reporting for mismatches (require, ordinal, descriptor mismatches).

Changed

• Logging improved to better highlight applied/failed actions and why.

Fixed

• Numerous stability issues from v1 where patches would silently not apply, apply inconsistently, or fail due to classloader visibility.
• Reduced risk of NoClassDefFoundError / runtime linkage issues by eliminating runtime references to patch classes.

Performance

• Faster and more reliable patch discovery (no expensive scanning; index is read directly).
• More predictable weaving and reduced nondeterministic behavior across environments.
