## News

* Numbers of FreeBSD-head-amd64-test_zfs are changed after OpenZFS importing,
we encouage everyone check and fix the failing and skipped test cases.

## Failing jobs

* https://ci.freebsd.org/job/FreeBSD-head-amd64-gcc6_build/
There are still mutiple errors when building with gcc6, error log available at
