Full Changelog: v0.2.2...v0.2.3

v0.2.2

Changes

Core Dependencies

• Added duckdb>=1.4.3 for efficient data querying
• Added pandas>=2.3.3 for enhanced data manipulation
• Added async-lru>=2.0.5 for async caching capabilities

Type System Enhancements ( src/agentics/core/atype.py )

• Added comprehensive docstring to pydantic_model_from_dict() function explaining:
• Dynamic Pydantic model creation from sample dictionaries
• Type inference and field name normalization
• Usage examples and edge cases
• Renamed composition fields from left/right to target/source for semantic clarity:
• target : The destination type in a composition
• source : The source type in a composition
• Removed debug print statement from create_pydantic_model()

Default Types ( src/agentics/core/default_types.py )

• Added Abool type: A new semantic type for boolean values with type validation
• Ensures only boolean values are accepted during construction
• Follows the same pattern as existing Astr type

Transduction Improvements ( src/agentics/core/transducible_functions.py )

• Enhanced Transduce class with string representation methods:
• Added str() : Human-readable string output
• Added repr() : Developer-friendly representation
• Added _one_to_str() : Handles Pydantic models, dicts, lists, and generic types
• Added new parameters to transducible() decorator:
• transduce_fields : List of specific fields to transduce
• prompt_template : Custom prompt template for transduction
• Fixed transduction return type: Now returns TransductionResult consistently
• Fixed generate_prototypical_instances() : Updated field definition to use optional list

Core AG Enhancements ( src/agentics/core/agentics.py )

• Improved batch processing:
• Transduction now chunks inputs using amap_batch_size for better memory management
• Processes chunks sequentially to handle large datasets
• Fixed state merging logic:
• Now filters output fields against allowed model fields (Pydantic v2 compatibility)
• Prevents errors from extra fields in merged states
• Validates AG lengths before merging
• Enhanced explanation generation:
• Improved prompt instructions for better semantic understanding
• Renamed explanation variables for clarity ( left/right → target/source )
• Added confidence scoring guidance to LLM
• Improved compose_states() method:
• Changed from nested loops to paired zip() iteration (matching AG lengths)
• Fixed semantic naming: left/right → target/source
• More efficient and semantically correct composition
• Better error handling:
• Added validation in merge_states() to check length compatibility
• Meaningful error messages for debugging
• Truncated display names: Limited AG names to 30 characters in progress descriptions

v0.2.2a2 Preview - Semantic operators improvements

Changes

This alpha release includes significant improvements to the Agentics framework's type composition system and transduction capabilities.

Key Features

• Improved Batch Processing: Transduction now chunks inputs for better memory management
• Better State Merging: Fixed Pydantic v2 compatibility with proper field filtering
• Enhanced Explanations: Improved LLM instructions for more meaningful semantic transductions
• New Dependencies: Added duckdb, pandas, and async-lru for improved data handling

Technical Improvements
