AWS iot documentation change
Summary
Added get_registry_data() to list of external functions in error actions and removed detailed billing explanations for specific functions
Security assessment
The change adds a new function (get_registry_data) to the list of available external functions but does not indicate any security vulnerability being addressed. The removed billing details relate to cost considerations rather than security. No evidence of security fixes or new security guidance was introduced.
