[Release] crewaiInc/crewAI 1.14.7a4: 1.14.7a4

crewAI v1.14.7a4 introduces runtime migration for @listen/@router decorators to read from FlowDefinition and adds pluggable default backends for memory, knowledge, RAG, and flow components. This release enhances the framework's flexibility by allowing developers to swap backend implementations without code changes. The update includes documentation updates and contributions from three core team members.

Key Points

• •Migrate @listen/@router decorators to read configuration from FlowDefinition instead of hardcoded runtime values
• •Implement pluggable default backends for memory, knowledge, RAG, and flow modules
• •Enable flexible backend swapping without modifying core agent code
• •Improve separation of concerns between flow definition and runtime behavior
