Security Enhancements

Rocky Linux 9.0 has seen a couple of security most notably:

  • SELinux Improvements – Memory overhead, loading time, and performance have been substantially improved.
  • OpenSSH 8.7 p 1 is the latest version. Notable improvements include the replacement of SCP/RCP protocol with SFTP protocol which offers solid encryption and more predictable handling of filenames.
  • OpenSSL 3.0.1 is the newest version. It provides improvements such as a new versioning scheme, support for new protocols & algorithms, and an improved HTTP(S) client among many others.
  • Deprecation of SHA-1 message digest for cryptographic purposes. The hash functions associated with SHA-1 are no longer considered secure.

Filesystem Improvements

The XFS filesystem now supports Direct Access (DAX) operations allowing direct access to byte-addressable persistent memory. This helps to avoid the latency of leveraging traditional block I/O conventions. Additionally, NGS introduces an “eager write” mount option for minimizing latency.

GNOME 40

In Rocky Linux 9, GNOME 40 is the default desktop environment. GNOME 40 is freshly redesigned to provide a sleeker UI for a desktop operating system. Now more than ever, it’s much easier to launch your applications and arrange your personal workspace.

Notable improvements for desktop usage include:

  • Fractional display scaling.
  • Ability to group applications into folders using the drag and drop method thanks to the revamped ‘Activities‘ application.
  • Ability to mute notifications by toggling on “Do not disturb” which appears as a separate button in the notification.
  • The different refresh rates for every screen.
