 # Changelog
 
+## 0.9.10
+- Updates aws.lambda parser for Init Duration, incl. tests
+
+## 0.9.9
+- Improved error handling / descreased timouts calling AWS APIs to fail fast in case AWS throttles API calls

+- Skip over more invalid vpc flowlog entries
+
+## 0.9.8
+- Fix for ALB AccessLog parser to handle spaces in request_url
+- Improved VPC FlowLog metadata augmentation
+- better error handling for VPC FlowLog parsing
+
+## 0.9.6
+- Augment VPC FlowLogs with ENI metadata incl. global cache
+
+## 0.9.5
+- Added support for VPC FlowLogs
+
 ## 0.9.4
 - Improved S3 file type detection, also handles one line access logs
 - default fluentd upstream url scheme
