It’s not usual for elementary OS to get incremental builds of its releases, but thanks to a new release process that helps the development team tag and build ISO images much faster, there’s now a new spin of the elementary OS 5.1 “Hera” ISO release, versioned 5.1.2. elementary OS 5.1.2 is based on the Ubuntu 18.04.3 LTS (Bionic Beaver) operating system release, which means that it ships with the Linux 5.3 kernel that features support for AMD Navi GPUs, as well as for keyboards and trackpads of 2015 MacBook models, and many other hardware improvements.
