v0.5.3 fixes three bugs affecting agent operations: KeyError in optional use_aws parameters, batch concurrency failures, and context initialization.

Why it matters: Three bugs fixed: optional parameters in use_aws no longer throw KeyError, batch operations handle concurrency, context options initialize correctly. Update if using these features.
