Release notes v15
The result of an external security audit, every point fixed:
- Fixed a path-traversal bypass in {fetch}: allowed prefixes are now resolved via realpath() instead of a plain text-prefix comparison.
- {$engine.const.*} now always blocks sensitive constant name patterns (PASSWORD, SECRET, API_KEY, TOKEN, ...) – even without a security policy set.
- Fixed a crash in CacheManager when no engine instance is provided (nullable property instead of an uninitialized access).
- Debug output is now disabled by default instead of enabled by default.
- JavaScript escaping now also handles the Unicode line separators U+2028/U+2029.
