Per https://aws.amazon.com/security/security-bulletins/AWS-2021-005/, users of aws-lambda-java-log4j2 should update to v1.3.0. We were not able to determine whether aws-lambda-java-log4j:1.0.1 was safe or not, so it was decided that we should update to aws-lambda-java-log4j2:1.3.0 to be sure.
datadog-lambda-java:0.3.4 should behave exactly the same as 0.3.3.
barring any additional critical security fixes, this will probably be the last update to datadog-lambda-java:0.3.x. Additional updates will be in v1.4.x
