Dear Qubes Community,
Shortly after the announcement of 4.0.2 [1], a bug [2] was discovered in
the dom0 kernel included in that release. Since the bug would have
presented installation problems for the majority of users. That bug has
now been fixed, along with a few installer fixes, resulting in
4.0.3-rc1.
In keeping with standard semantic versioning [3], we've incremented the
patch version number to reflect this latest fix, so 4.0.2 has become
4.0.3. This is the first release candidate (rc1) for 4.0.3, because we'd
like to give the community an opportunity to test it before declaring it
to be the stable release. However, the changes from 4.0.2 are minimal,
and 4.0.2 itself was preceded by three release candidates, so we plan to
keep the 4.0.3-rc1 testing period brief.
As with 4.0.2, 4.0.3-rc1 includes many updates over the initial 4.0
release, in particular:
- All 4.0 dom0 updates to date
- Fedora 30 TemplateVM
- Debian 10 TemplateVM
- Whonix 15 Gateway and Workstation TemplateVMs
- Linux kernel 4.19 by default
Qubes 4.0.3-rc1 is available on the Downloads page:
https://www.qubes-os.org/downloads/
What is a point release?
========================
A point release does not designate a separate, new version of Qubes OS.
Rather, it designates its respective major or minor release (in this
case, 4.0) inclusive of all updates up to a certain point. Installing
Qubes 4.0 and fully updating it results in the same system as installing
Qubes 4.0.3.
What should I do?
=================
If you installed Qubes 4.0, 4.0.1, or 4.0.2 and have fully updated [4],
then your system is already equivalent to a Qubes 4.0.3 installation. No
further action is required.
Regardless of your current OS, if you wish to install (or reinstall)
Qubes 4.0 for any reason, then the 4.0.3 ISO makes this more convenient
and secure, since it bundles all Qubes 4.0 updates to date.
*Note:* The Qubes 4.0.3 ISO will not fit on a single-layer DVD (for the
technical details underlying this, please see issue #5367 [5]). Instead,
we recommend copying the ISO onto a sufficiently large USB drive. [6]
However, if you would prefer to use optical media, we suggest selecting
a dual-layer DVD or Blu-ray disc.
Release candidate planning
==========================
If no major issues are discovered in 4.0.3-rc1, we expect the stable
release of 4.0.3 to follow sometime next week. As usual, you can help by
reporting any bugs you encounter. [7]
