OmniOSce v11 r151060 is out!

On the 2nd of November 2026, the OmniOSce Association has released a new stable version of OmniOS - The Open Source Enterprise Server OS. The release comes with many tool updates, brand-new features and additional hardware support. For details see the release notes.

Highlights include:

  • Significant performance improvements in the IPS packaging system - pkg starts faster, uses far less memory, installs and removes packages in a fraction of the time, and the dependency solver now explains concisely why an operation cannot be satisfied. Run pkg update-format after upgrading to convert existing images to the new format and benefit fully;
  • NFSv4.1 delegations in the NFS server, and SMB 3.1.1 support in the SMB client;
  • posix_spawn() is now implemented in the kernel and is significantly faster;
  • multiple queue pairs and event index support for virtio networking, improving network performance in virtual machines, along with IPv6 TSO offload and other improvements for bhyve guests;
  • the new zpool wait command;
  • address space layout randomisation (ASLR) enabled by default on new installations;
  • OpenSSH 10.6p1 - check the release notes for changes in behaviour which may affect existing configurations.

Note that r151056 is now end-of-life. You should upgrade to r151058 or r151060 to stay on a supported track. r151054 is a long-term-supported (LTS) release with support until May 2028.

OmniOS is fully Open Source and free. Nevertheless, it takes a lot of time and money to keep maintaining a full-blown operating system distribution. Our statistics show that there are almost 2’000 active installations of OmniOS while fewer than 20 people send regular contributions. If your organisation uses OmniOS based servers, please consider becoming a regular patron or taking out a support contract.

Any problems or questions, please get in touch.
