[0.3.0] - 2025-12-20

Added

• Tests: Added tests for nested Object and Array access via get<Object>() and get<Array>() methods

Removed

• Breaking: Removed std::string_view support from Document, Object, and Array classes
  • get<std::string_view>(), set<std::string_view>(), and append<std::string_view>() are no longer available
  • This API created dangling references by returning views to temporary strings
• Breaking: Removed Serializer<T> instance methods serializeToString() and deserializeFromString()
  • These methods were redundant - use static methods Serializer<T>::toString() and Serializer<T>::fromString() instead
  • Instance methods serialize() and deserialize() (working with Document) are still available

Fixed

• Critical: Fixed dangling pointer bugs in Object::get<Object>(path) and Object::get<Array>(path) methods
  • These methods were creating temporary Document objects and returning Object/Array wrappers with pointers to the temporaries
  • After function return, the temporary was destroyed, leaving dangling pointers causing undefined behavior and segmentation faults
  • Now correctly returns Object/Array with references to the parent document and proper path
• Critical: Fixed dangling pointer bugs in Array::get<Object>(path) and Array::get<Array>(path) methods
  • Same issue as above - temporary documents were being destroyed after return
  • Now correctly returns Object/Array with references to the parent document and proper path

[0.2.0] - 2025-11-30

Added

• nfx-stringutils dependency: Added nfx-stringutils as a FetchContent dependency for string validation functions

Changed

• Format validation: Replaced all std::regex usage with constexpr nfx::string:: functions for ~50% performance improvement
• SchemaGenerator: Improved IDN/IRI detection for email, hostname, and URI format inference

Removed

• Regex.h: Deleted nfx::serialization::json::regex namespace (replaced by nfx-stringutils)
