The developers of FreeBSD have made available the second BETA of version 12.0. Changes in this version are binary compilation debug fix, gif_interfaces rc.conf(5) variable restored, Linux compatibility layer update, driver removals, and various bug fixes. As usual, try it out in a non-production environment. You may download the ISO/image file here.
A summary of changes since 12.0-BETA1 includes: o A debug option during binary compilation which was missed when branching stable/12 had been turned off. o The gif_interfaces rc.conf(5) variable had been restored. (PR 204700) o The timezone database files have been updated to version 2018f. o The debug.witness.trace entry in sysctl.conf(5) on installation media had been removed. o A system panic triggered by a combination of lagg(4) and vlan(4) had been fixed. (PR 227654) o The ability to prevent interrupting the boot process without entering the password in loader.conf(5) had been fixed. (PR 207069) o Several drivers originally targeted for removal in 12.0-RELEASE had been removed from the GENERIC kernel configuration on amd64 and i386. o An off-by-one error that could lead to a system panic with the sound(4) driver had been fixed. o The mlx5(4) driver had been updated to notify when a port on ConnectX-6 network cards had been turned off due to insufficient power. o The filter_reloc() function in objcopy(1) had been restored, which fixes building GCC. o The shared library version of OpenSSL in the base system had been increased from '9' to '111' in order to prevent shared library version collisions with OpenSSL installed via pkg(8) or the Ports Collection. o Updates to the Linux compatibility layer. o The ae(4), bm(4), cs(4), de(4), dme(4), ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), vx(4), wb(4), and xe(4) drivers have been deprecated.
