[2019-07-04] An issue which can cause a crash when connecting to a bhyve(4) instance with a VNC client under certain circumstances had been reported. An errata notice is planned post-release.
[2019-07-04] An issue booting bhyve(4) virtual machines compiled with clang(1) version 8.0.0 or later had been reported late in the release cycle. An errata notice is planned post-release.
This issue is believed to only affect OpenBSD virtual machines compiled with clang(1).
[2019-07-04] An issue when upgrading from FreeBSD�11.3
to FreeBSD�12.0 (which occurred earlier in time,
comparatively), had been reported where the
com.delphix:spacemap_v2
zpool(8)
feature does not exist on FreeBSD�12.0, will fail to
import the ZFS pool.
At this time, it is advised to defer migrating from FreeBSD�11.3 to FreeBSD�12.x until FreeBSD�12.1 is available.
Upgrading from earlier FreeBSD�11.x releases to FreeBSD�12.0 are believed to be unaffected.
[2019-12-06] An issue has been reported with the FreeBSD�11.3-RELEASE images on the Google Compute Engine platform which causes virtual machines to fail to start properly.
While we intend to investigate how to handle similar situations should they arise in the future, updated images will not be provided as of this time.
Users wanting to use FreeBSD in Google Compute Engine are
advised to use 12.0-RELEASE or 12.1-RELEASE, or for those
who wish to track 11.X
, the
freebsd-11-3-stable-amd64-v20190801
snapshot from stable/11
has been
reported to work correctly.
