Over 100 bug fixes and features were merged since the v1.0.0 release.
Some Highlights:
Go modules now supported
Support for new features in more recent kernels
Extended support for filters, actions, and tunnels
Support for bonds, ipoib, rdma
More features for vfs
We have been careful to preserve the existing functionality from release v1.0.0. There is one minor change to AddrAdd where it will no longer automatically set a broadcast address when you set a /31 or /32 address
If you notice any differences in behavior, please file an issue
