RHEL 7.x-grenen understøttes parallelt med RHEL 8.x and will be supported until June 2024. The first phase of support for the RHEL 7.x branch, which includes functional improvements, has completed. The release of RHEL 7.8 marked overgangen the transition to the maintenance phase, where the priorities shifted towards bug fixes and security, with minor improvements related to major hardware systems support. For those wishing to upgrade to the new branch, after the release of Red Hat Enterprise Linux 8.2, users will have the opportunity to upgrade from Enterprise Linux 7.8.

De mest bemærkelsesværdige Optimeringer:

• The interface for switching virtual desktops in the GNOME Classic environment has been changed; the switch button has been moved to the lower right corner and designed as a bar with thumbnails.
• Support for new Linux kernel parameters has been added (mostly related to managing the protection against new attacks on the CPU speculative execution mechanism): audit, audit_backlog_limit, ipcmni_extend, nospectre_v1, tsx, tsx_async_abort, mitigations.
• For guest systems running Windows that use ActivClient drivers, the ability to share access to smart cards has been implemented.
• The samba package has been updated to version 4.10.4.
• An implementation of the SHA-2 algorithm optimized for IBM PowerPC processors has been added.
• OpenJDK now supports encryption using the elliptic curve secp256k1.
• Full support for Aero SAS adapters (mpt3sas and megaraid_sas drivers) has been provided.
• An EDAC (Error Detection and Correction) driver for Intel ICX systems has been added.
• The ability to mount partitions using the FUSE mechanism in user namespace ID spaces has been implemented, which allows the use of the fuse-overlayfs command in containers without root.
• The limitation on the number of IPC identifiers (ipcmin_extend) has been increased from 32 thousand to 16 million.
• Full support for Intel Omni-Path Architecture (OPA) has been provided.
• A new role 'storage' (RHEL System Roles) has been added, which can be used to manage local storage (file systems, LVM volumes, and logical partitions) using Ansible.
• In SELinux, launching a graphical session for users in the sysadm_u group has been permitted.
• Support for DIF/DIX (Data Integrity Field/Data Integrity Extension) for certain Fibre Channel Host Bus Adapters (HBA) has been added. Full support for NVMe/FC (NVMe over Fibre Channel) has been added to Qlogic HBA.
• Der er sikret eksperimentel (Technology Preview) understøttelse af OverlayFS, Btrfs, eBPF, HMM (heterogen hukommelsesstyring), kexec, SME (Secure Memory Encryption), criu (Checkpoint/Restore in User-space), Cisco usNIC, Cisco VIC, Trusted Network Connect, SECCOMP i libreswan, USBGuard, blk-mq, YUM 4, USB 3.0 i KVM, No-IOMMU for VFIO, konvertering af Debian- og Ubuntu-billeder via virt-v2v, OVMF (Open Virtual Machine Firmware), systemd-importd, DAX (direkte adgang til FS uden at bruge sidetilstandscache uden anvendelse af blokniveau) i ext4 og XFS, kørsel af GNOME-desktop ved brug af Wayland, fraktionel skalering i GNOME.
