Added * Firecracker uses two different named pipes to record human readable logs and metrics, respectively. Changed * Seccomp filtering can be enabled via setting the `USE_SECCOMP` environment variable. * It is possible to supply only a partial specification when attaching a rate limiter (i.e. just the bandwidth or ops parameter). * Errors related to guest network interfaces are now more detailed. Fixed * Fixed a bug that was causing Firecracker to panic whenever a PUT request was sent on an existing network interface. * The id parameter of the jailer is required to be an RFC 4122-compliant UUID. * Fixed an issue which caused the network RX rate limiter to be more restrictive than intended. * API requests which contain unknown fields will generate an error. * Fixed an issue related to high CPU utilization caused by improper KVM PIT configuration. * It is now possible to create more than one network tun/tap interface inside a jailed Firecracker.
