Previously, the Amazon Web Services (AWS) check for EC2 limits had an option to fetch limits from the AWS API, but several limits were still using hardcoded defaults instead:

VPC Elastic IP addresses: hardcoded to 5 — now read from the AWS Service Quotas API (quota: "EC2-VPC Elastic IPs")
VPC security groups: hardcoded to 2500 — now read from the AWS Service Quotas API (quota: "VPC security groups per Region")
VPC security groups of elastic network interface: hardcoded to 5 — now read from the AWS Service Quotas API (quota: "Security groups per network interface")

If you've raised any of these quotas above their defaults in your AWS account, the AWS/EC2 Limits service will now reflect your actual quota.
