This is a fairly big release, implementing complete support for OpenWrt (currently only the nftables-based installs are supported, iptables support will be implemented soon'ish). Also lots of under-the-hood stuff has been changed and improved, including the usage() functions in several scripts, error and console messages. Much of the code has been compacted.
Full Changelog: v0.2.0-nftables...v0.2.1-nftables
