• Use data_collection.http_headers.request for ip address collection (both env and request)
  • Sensitive headers like auth and cookies are now ALWAYS filtered unlike before
• Use data_collection.cookies for cookie collection (fix Hash signature since it always was one)
• Use data_collection.url_query_params for query string and parse query into Hash and filter
• Use data_collection.http_bodies for body
  • JSON is also parsed and filtered now, form data is also filtered for sensitive keys
• Deprecate rack_env_whitelist, will be removed in major
