Red Hat announced the release of Red Hat Enterprise Linux (RHEL) 7.6 on October 31. Apart from the usual package updates and security improvements, there were a number of notable depreciations in the release notes. Some of them were expected and have been mentioned before, such as the migration to Python 3 and the plan to drop Python 2 from future major versions of RHEL. The Sendmail mail service is being replaced by Postfix and Btrfs (an advanced file system) will not be offered in future major versions of RHEL. Future versions will also drop support for KDE Plasma, suggesting Red Hat plans to streamline its support coverage: "KDE Plasma Workspaces (KDE), which has been provided as an alternative to the default GNOME desktop environment has been deprecated. A future major release of Red Hat Enterprise Linux will no longer support using KDE instead of the default GNOME desktop environment."
