Oracle Linux 9 Developer Preview is ready for download

Approximately three weeks after the release of the 8.6 version, Oracle Linux 9 Developer Preview is released. This release is based on the Red Hat Enterprise Linux (RHEL) 9, which also has been released at about the same time as Oracle Linux 8.6.

Offers two kernel choices

Oracle Linux 9 Developer Preview comes with many new features and improvements. The Developer Preview version comes with both the Unbreakable Enterprise Kernel (kernel-uek-5.15.0-0.23.1.el9uek) and Red Hat Compatible Kernel (kernel-5.14.0-1.7.1.el9) packages.

It brings automatic network activation in the graphical installation interface and locks the root account by default. On the kernel side, the RHCK kernel is now signed with trusted SecureBoot certificates which eliminate the need to enroll a separate public key while UEFI Secure Boot is enabled. The compilers’ and development tools’ package versions can be seen below:

  • System toolchain components
    • GCC 11.2.1
    • glibc 2.34
    • binutils 2.35.2
  • Performance tools and debuggers
    • GDB 10.2
    • Valgrind 3.18.1

  • Compiler toolsets
    • LLVM Toolset 13.0.1

    • Go Toolset 1.17.7
  • python-jsonpointer is rebased to version 2.0
  • grafana-pcp is rebased to 3.2.0

Oracle Linux 9 Developer Preview is shipped with GNOME 40 desktop environment and it replaces PulseAudio / Jack audio services with Pipewire. The file system options deliver some enhancements as well, and exFAT is now supported. The dynamic programming languages and web/database server-related packages are also updated, which can be seen below:

  • Node.js 16
  • Ruby 3.0.3
  • Perl 5.32
  • PHP 8.0
  • Git 2.31 and Git LFS 2.13
  • Subversion 1.14

  • Varnish Cache 6.6
  • Squid 5.2
  • MySQL 8.0
  • Redis 6.2
