Red Hat announced a new version of their Red Hat Enterprise Linux distribution on August 1st. The new release, version 7.4, contains mostly minor updates and a few security improvements. Old and vulnerable cryptography functions were removed and file system improvements were introduced. One of the more popular additions to Red Hat's product may be the real-time kernel which will be useful for systems with timing consistency requirements. One announcement that caused some surprise was the plan to remove the advanced Btr file system from future releases: "The Btrfs file system has been in Technology Preview state since the initial release of Red Hat Enterprise Linux 6. Red Hat will not be moving Btrfs to a fully supported feature and it will be removed in a future major release of Red Hat Enterprise Linux. The Btrfs file system did receive numerous updates from the upstream in Red Hat Enterprise Linux 7.4 and will remain available in the Red Hat Enterprise Linux 7 series. However, this is the last planned update to this feature."
