4. Open Issues

  • [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.

5. Late-Breaking News

  • [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.
