# knife-ec2 0.10.rc.0 release notes: This release of `knife-ec2` adds improvements around ssh configuration and EC2 IOPS provisioning. There is also a dependency update for the `fog` and `knife-windows` gems to improve support for additional EC2 capabilities and Windows authentication enhancements respectively.
