Description

Each component in Strands now yields callback events to the Agent class, which in turn passes the events to the configured callback handler. Consequently, we no longer need to pass around the callback handler throughout code.

strands-agents/docs#113

Type of Change

• Bug fix
• New feature
• Breaking change: This is a breaking change for customers who invoke callbacks in their custom tools. This is a pattern we want to discourage. Instead, we will ask customers to yield events from their tools and in turn, pass those events to the callbacks on their behalf. We are announcing this in [ANNOUNCEMENT] Upcoming Breaking Changes #253.
• Documentation update
• Other (please describe):
