• 🐛 Fixed a bug where two jars running in the same instance would have overlapping Skidfuscator factories, causing one of them to fail


  • ✨ NEW Added compatibility for J20 and J21. Skidfuscator now supports J7->J21
  • ✨ NEW Flow Gen 3.1! New, better, improved. Now supports modularity switch, with 3 random parameters
  • ✨ Improvements to String Encryption, Flow Obfuscation, and more!
  • ✨ New console look!
  • ✨ Unintentionally added shrinking mechanics. Bigger jars will be... smaller... with obfuscation (???)
  • 🐛 Fixed a bug where verification would attempt to check non hierarchal libraries, adding redundancy
  • 🐛 Fixed a bug where Driver would return null due to collision
  • 🐛 Fixed a bug where InterfConstRef would be invalid
  • 🐛 Fixed a bug where clone implicit bridge would be obfuscated, causing conflicts
  • 🐛 Improved hierarchy caching in speed, accuracy and efficiency
  • 🐛 Fixed a bug where hierarchy would conflict method groups and not properly define them
  • 🐛 Fixed a bug where method exemptions for groups would fail to check class parent exemptions
  • 🐛 Fixed a bug where an exempted local method would break and not properly reflect gen 3 flow changes
  • 🐛 Fixed a bug where improperly cached invocation would be attempted to be read as an expression
  • 🐛 Improved outputting speed by caching the output mappings map
  • 🐛 Fixed a bug where exempted classes would never receive any bytecode level modifications
  • 🐛 Fixed a bug where exempted classes would not rename invocations
  • 📚 More documentation to wiki
