Qubes OS
Compartmentalized desktop, stable release 4.3.2.
Published by The Qubes team.
In short
Qubes OS is the compartmentalized desktop from the Qubes team. On 20 Oct 2026 the downloads page said Qubes OS 4.3.2 is the latest stable release and named the ISO Qubes-R4.3.2-x86_64.iso. The release notes are dated 2026-10-02 and call 4.3.2 a patch release. They say the default Fedora template moved to Fedora 44 and kernel-latest moved to Linux 7.2. Qubes 4.2 is end of life on that page. The license text was not read after a redirect, so no SPDX id is stated. The download did not print a price.
Product pricing strategy
02
Free
The downloads page publishes the 4.3.2 ISO, a signature, and a torrent, and it does not print a dollar price. No paid Qubes edition was on that page or the 2 Oct 2026 release notes. The summit in Berlin is an event with tickets mentioned on the download page as a link. This listing did not open a ticket price, so none is quoted. Fedora 44 as the default template is a version fact, not a Red Hat subscription you buy from the Qubes page. Do not invent a support contract. If a hardware partner sells a preinstalled laptop, that price lives on the partner's page and was not opened here.
Utility and features
03
The downloads page says Qubes OS 4.3.2 is the latest stable release and recommends it for new and existing users. The ISO name printed there is Qubes-R4.3.2-x86_64.iso, with a detached signature and a torrent. The release notes, dated 2026-10-02 by the Qubes team, call it a patch release that collects security updates and bug fixes since the previous stable release. What is new, on that page, is a default Fedora template upgraded to Fedora 44, kernel-latest upgraded to Linux 7.2, security updates, and bug fixes. The same notes say Qubes 4.2 has reached end of life and tell 4.2 users to upgrade to 4.3.
- Stable ISO 4.3.2. The downloads page on 20 Oct 2026 said 4.3.2 is the latest stable release and named Qubes-R4.3.2-x86_64.iso.
- Fedora 44 and Linux 7.2. The 2026-10-02 notes say the default Fedora template moved to Fedora 44 and kernel-latest moved to Linux 7.2.
- 4.2 is end of life. The same notes say Qubes 4.2 has reached end of life. The license body was not read, so no SPDX id is claimed.
A note on that page gives the summit dates as October 30 to November 1 in Berlin. This listing quotes the dates and does not copy the announcement's urgency line. The license document URL on qubes-os.org redirected onward, and the license body was not captured, so this listing does not invent an SPDX identifier. A github.com path tried for qubes-os returned 404, so no GitHub field is set. Whonix's download table lists Qubes as a host. That is Whonix on Qubes, which is a different install from the Qubes ISO itself. Tails remains the amnesic USB.
- 1
Download 4.3.2 for a new install. Treat 4.2 as end of life, as the notes say.
- 2
Keep Fedora 44 and Linux 7.2 attached to the 4.3.2 notes.
- 3
Use qubes to separate work. Do not treat a qube as permission to reach a system you do not own.
Caveats
04
Qubes 4.3.2 is the stable ISO. Qubes 4.2 is end of life, which the 2 Oct 2026 notes say outright. Do not describe 4.2 as current. Fedora 44 and Linux 7.2 belong to the 4.3.2 notes. Do not paste them onto an older release.
The license text was not read after the redirect, so this page does not name a SPDX id. The tried GitHub repository URL returned 404. Compartments reduce the blast radius of one qube. They do not make a network action authorized, and they do not replace the attribution rules of an investigation. The release notes also describe an in-place update for people already on 4.3. This listing does not repeat those commands.

Potential use cases
06
- Qubes 4.2 is about to be called current. The downloads page on 20 Oct 2026 said 4.3.2 is the latest stable release and named Qubes-R4.3.2-x86_64.iso. The notes dated 2026-10-02 say 4.2 has reached end of life. They also say the default Fedora template moved to Fedora 44 and kernel-latest moved to Linux 7.2. Those facts belong to 4.3.2.
- A license id is about to be invented. The license URL redirected and the body was not read. A github.com/QubesOS/qubes-os request returned 404, so no GitHub field is set. No dollar price was on the download page. The summit dates on that page are October 30 to November 1 in Berlin. A ticket price was not opened.
- A qube is about to be briefed as permission. Compartments separate work on one computer. They do not authorize a network action, and they are not the same install as Whonix's Qubes host option. Quote the ISO for a new Qubes install, and quote Whonix's table only when the job is Whonix.
Hard cases
The case where the first result is easy to over-read.
Fedora 44 is assigned to Qubes 4.2
Fedora 44 and Linux 7.2 are in the 4.3.2 notes. Qubes 4.2 is the release those notes say has reached end of life. Putting the new template on 4.2 reverses the page. Keep the template on 4.3.2.
