• fix: build issues with -fmodules flag by @greghuels in #47

Full Changelog: v2.0.0...v2.0.1

v2.0.0

Added

• EvaluationClient - lightweight client for flag evaluation that can be used for manual synchronization
• ConfigurationStore convenience API for setting configuration by value:
  • ConfigurationStore(Configuration config) - constructor accepting Configuration by value
  • setConfiguration(Configuration config) - setter accepting Configuration by value
• Move constructor and move assignment operator for Configuration class
• parseConfiguration() convenience function for simplified configuration parsing:
  • parseConfiguration(flagConfigJson, error) - parse flags only with error feedback
  • parseConfiguration(flagConfigJson, banditModelsJson, error) - parse flags and bandits together
  • Provides simple string-based error handling for common use cases
  • Built on top of ParseResult<T> for structured error collection
• parseConfigResponse() and parseBanditResponse() functions returning ParseResult<T>:
  • Support parsing from both JSON strings and input streams
  • Collect all parsing errors instead of failing on first error
  • Enable partial success handling (return value with warnings)
• New ParseResult<T> template for structured error reporting during parsing
• Support for building without exceptions via -fno-exceptions flag
• Abort-free configuration parsing - all parsing operations can now fail gracefully

Changed

• BREAKING: ConfigurationStore::getConfiguration() now returns std::shared_ptr<const Configuration> instead of Configuration by value
  • Eliminates expensive configuration copies on every flag evaluation
• BREAKING: Configuration constructors now take parameters by value for better performance
• BREAKING: SDK now uses RE2 regex library instead of std::regex
  • RE2 is not vulnerable to ReDoS (Regular Expression Denial of Service) attacks
  • RE2 works without exceptions, enabling exception-free builds
  • This change improves security and reliability
• ConfigurationStore now uses atomic operations instead of mutex internally for better performance
• BREAKING: Parsing functions now report errors instead of silently skipping invalid entries:
  • parseConfigResponse() and parseBanditResponse() return ParseResult<T> with error collection
  • Use the new parseConfiguration() convenience function for simplified error handling
  • Errors are aggregated and returned rather than causing silent data loss
• BREAKING: client.getBoolAssignment renamed to client.getBooleanAssignment for consistency with getBooleanAssignmentDetails
