2024-10-01	Enhancement: - Added support for new unparsed logs of type AWS_VPC_FLOW.
2024-07-31	Enhancement: - Added support for JSON format logs.
2023-04-06	Enhancement - Mapped "metadata.event_type" to "GENERIC_EVENT" where both "srcaddr" and "dstaddr" is not present.
2022-10-18	Enhancement - Modified mapping for the value of following fields from "additional.fields" to "about.resource.attribute.labels" : - "interfaceId" , "packets" , "SubnetID" , "logStatus" ,"tcp_flags" ,"traffic_path" ,"start_time" ,"end_time", "sublocation_id","sublocation_type" ,"pkt_dst_aws_service" ,"pkt_src_aws_service". - Added grok pattern to parse logs in which "destination_port" might not be present.
2022-07-07	Enhancement - The newly ingested SYSLOG format logs have been parsed and handled using proper grok pattern.
2022-05-30	Enhancement - Modified the grok pattern to avoid incorrect mapping of UDM fields. Mapped 'start_time', 'end_time', 'traffic_path', 'sublocation_id', 'sublocation_type', 'pkt_dst_aws_service' and 'pkt_src_aws_service' to 'additional.fields'. Added a new grok pattern to parse the logs of different format. Mapped 'flow_direction' to 'network.direction'. Mapped 'az_id' to 'principal.cloud.availability_zone'.
