Changelog

Stay up to date with the latest improvements, bug fixes, and new features in wYnFuscate.

BetaJanuary 11, 2026

Runtime-Encrypted Functions

  • NewAdded WYNF_ENC_FUNC macro — encrypt function bodies at build time, decrypt at runtime with a key from your server
  • NewAdded Hex Key Generator tool in Dashboard Settings — generate secure 64-character hex strings for use with WYNF_ENC_FUNC
  • SecuritySupports whitelist/key-server workflows where critical functions only work with a valid runtime key
  • SecurityFail-closed behavior: wrong key or tampering causes trap, not garbage output
BetaJanuary 11, 2026

Dashboard Improvements

  • NewAdded code editor to upload page — paste Lua code directly instead of uploading a file, with syntax highlighting and line numbers
  • NewAdded copy-to-clipboard button for completed jobs (files under 4MB) in job history and job details pages
  • NewAdded bulk operations to job history — select multiple jobs to delete or download as ZIP
  • ImprovedAdded tooltips to action buttons throughout the dashboard for better discoverability
BetaJanuary 11, 2026

Security Macros & Dead Code Pruning

  • NewAdded WYNF_SECURE_CALL macro for restricting functions to VM-only callers — external calls are rejected (fail-closed)
  • NewAdded WYNF_SECURE_CALLBACK macro for securing event handlers and callbacks passed to Roblox APIs with fail-quiet behavior
  • ImprovedWYNF_OBFUSCATED now prunes dead branches in obfuscated builds (dev/fallback code is removed from the output)
BetaJanuary 10, 2026

New Macros

  • NewAdded WYNF_ENC_NUM macro for encrypting sensitive numeric constants like product IDs and feature flags
  • NewAdded WYNF_LINE macro for stable source line numbers in error messages and debug logs
  • NewAdded WYNF_NO_UPVALUES macro for callback compatibility with certain environments while maintaining protection
BetaJanuary 9, 2026
