V1.4.0

​

Core Changes

• Migration to Pipeline - Library code migrated to use new Pipeline replacing legacy RawChain and ResultChain
• Response Generation - Enhanced ResponseGenerator with improved error handling using CanCarryState interface
• Partial Response Validation - Updated validation flow to use new state interface
• Type Safety Improvements - Better type annotations and interface compliance across pipeline components

​

Breaking Changes

• JsonSchema factory methods - Parameter order changed in factory methods:
  • Old: JsonSchema::string($name, $nullable, $description)
  • New: JsonSchema::string($name, $description, $title, $nullable)
• Pipeline interfaces - Introduction of CanCarryState interface may affect custom pipeline processors (update type hints from ProcessingState to CanCarryState)

​

JsonSchema Package

• Fixed parameter ordering - Corrected JsonSchema factory method parameter order for consistent API across string(), integer(), number(), boolean(), enum(), array(), and collection() methods
• Enhanced nullable handling - Fixed bug where nullable property was incorrectly set when description was passed as second parameter

​

Pipeline Package

• CanCarryState Interface - Introduced new CanCarryState interface for improved state management abstraction
• ProcessingState Optimizations - Slimmed down ProcessingState class for cleaner API
• Enhanced Error Handling - Improved error extraction and processing with better type safety

​

Bug Fixes

• JsonSchema nullable property - Fixed critical bug where nullable: true was incorrectly set in JSON schema output when description was passed as nullable parameter
• Parameter type coercion - Resolved issue where string descriptions were being cast to boolean for nullable property

​

Documentation

• Pipeline Documentation - New CHEATSHEET.md and OVERVIEW.md with current API patterns
