This is the next release of OSv since the previous one 0.52.0 was crafted. Unlike previous one this release does deliver new exciting feature - it supports running OSv on new lightweight hypervisor firecracker which makes possible to boot OSv Read-Only FS image in as low as 5ms per bootchart. We hope next release will happen before end of second quarter of 2019.
