Breaking Changes

●Issue #1

The base index now uses 'id_' instead of 'get_doc_id()', which may affect custom index implementations relying on the old method name.

Migration Steps

  1. 1
    Update custom index implementations to use 'id_' instead of 'get_doc_id()'.
  2. 2
    Migrate away from deprecated agent packages to supported core alternatives.
  3. 3
    Ensure aioboto3 is updated if using Bedrock-related integrations.

Release Summary
