The FreeBSD RE team has announced the public availability of FreeBSD 12.1 RC1. This is the first release candidate in projects 12.1 series and brings a lot of stability and security improvements over the previous BETA releases.
As usual, FreeBSD 12.1 RC1 is available for a wide range of platforms and devices ranging from Power PCs to small embedded systems. The distribution can be installed by burning on an optical disk or using a USB storage device.

So, it is not recommended to install this release on production systems. This release is mainly for community QA persons who would like to test the release and report bugs in proper channels. Depending on the severity and frequency of bugs reported, it will be fixed before the final release or in subsequent patches.
