[2019-11-04] A late issue was discovered where systems
using the graphics/drm-kmod port built on
FreeBSD�12.0-RELEASE will crash during boot. It is
advised to remove the port prior to upgrading, and build the
port instead of using the upstream binary package.
[2019-11-22] The FreeBSD�12.1-RELEASE announcement includes mention of FreeBSD/amd64 Amazon� EC2™ AMIs (Amazon Machine Images). Though it also included mention of FreeBSD/aarch64 being available in various regions, it had not passed third-party validation for inclusion in the Amazon� Marketplace.
FreeBSD�12.1-RELEASE aarch64 Amazon� EC2™ AMIs are now available in the Marketplace here.
