crewAI's 1.15.2a2 adds Bedrock support and flow improvements

crewAI, the open-source multi-agent orchestration framework with 54.7k GitHub stars and 7.7k forks, has released version 1.15.2a2 as a pre-release. This update focuses on expanding integration options and refining flow agent functionality. The standout feature is the addition of `aiobotocore` to the Bedrock extra, enabling seamless use of Amazon Bedrock as a model provider within crewAI pipelines. This bridges the gap between crewAI's agent orchestration and AWS's managed foundation models, giving developers more flexibility in model selection.

Flow agents receive several enhancements: new document flow agent options, a text helper for flow skill examples, and a dedicated text helper for flow CEL prompts. These tools improve the flexibility and readability of agent workflows. The release also introduces streaming documentation to the navigation, making it easier for users to find and understand real-time streaming capabilities. A critical bug fix rejects self-listening flow methods, preventing infinite loops in agent communication. Documentation updates include refreshed snapshots and changelogs for the previous v1.15.2a1. This pre-release sets the stage for more robust, production-ready multi-agent systems.
