Qubes OS 4.2 Releases With PipeWire Support And Refreshed Core Apps
|
||||
======
|
||||
Qubes OS 4.2 update features improved core apps, and more goodies!
|
||||
With a recent announcement, Qubes OS 4.2 was released, and it features some important improvements.
|
||||
|
||||
For context: **what is Qubes OS?**
|
||||
|
||||
Well, Qubes OS is an interesting take on what a Linux distro can be. It's very different from most distros out there, with a focus on being “ **A Reasonably Secure Operating System** ”.
|
||||
|
||||
It uses **security-isolated compartments** , called ' **qubes** ', that are kept separate from each other. One could have a qube for doing casual web-browsing, another for handling e-mails, and another for handling banking stuff; these are called ' **app qubes** '.
|
||||
|
||||
These app qubes are based on another type of qube called ' **template** ', which is usually running a Linux distro such as Fedora or Debian. It shares its root file system (all programs and files) with the other qubes based on it.
|
||||
|
||||
Due to which, you can run the same apps on different qubes. More on its architecture [here][1].
|
||||
|
||||
💡
|
||||
|
||||
Qubes OS is heavy on system resources (needs more RAM than usual).
|
||||
|
||||
Now that you know about the distro, let me highlight things from its latest release.
|
||||
|
||||
## 🆕 Qubes OS 4.2: What's New?
|
||||
|
||||
![][2]
|
||||
|
||||
Powered by [**Xen 4.17**][3] **, a secure bare-metal hypervisor,** Qubes OS 4.2 is here with some neat changes that improve the overall performance and usability.
|
||||
|
||||
Some of the **key highlights** include:
|
||||
|
||||
* **Dom0 with Fedora 37**
|
||||
* **Core App Improvements**
|
||||
* **Template Upgrades**
|
||||
* **PipeWire Support (Pending)**
|
||||
|
||||
|
||||
|
||||
### Dom0 with Fedora 37
|
||||
|
||||
The ' _dom0_ ' qube now features Fedora 37, which is powered by [Linux kernel 6.0][4], this should enable Qubes OS to take advantage of newer hardware, such as Intel 13th Gen Raptor Lake CPUs.
|
||||
|
||||
A ' _dom0_ ' qube is basically the ' **admin qube** ', this is used to administer the entire operating system.
|
||||
|
||||
It has been designed in a very security conscious manner like the rest of the OS, resulting in no network connectivity, and only being used to run the desktop environment, and the window manager.

||||

|
||||
|
||||
### Core App Improvements
|
||||
|
||||
![][6]
|
||||
|
||||
Another place where we see major changes is the **complete rewrite of some Qubes OS core apps** , which were done in a bid to improve the overall user experience.
|
||||
|
||||
What you saw above was the **new Qubes OS Policy Editor tool** , which has a very minimal interface with all the required options.
|
||||
|
||||
![][7]
|
||||
|
||||
The **Qubes OS Global Config app also sees an upgrade** , and it is now more intuitive to use, while unifying all the important settings under one roof.
|
||||
|
||||
![][8]
|
||||
|
||||
And finally, the **Qubes OS Update tool also receives a makeover** , with subtle changes here and there to make it more user-friendly.
|
||||
|
||||
### Template Upgrades
|
||||
|
||||
The included default templates have also been upgraded, with the default **Debian template now featuring Debian 12** , and **Xfce being the default desktop environment** for the Fedora and Debian templates.
|
||||
|
||||
### PipeWire Support
|
||||
|
||||
After a long wait, Qubes OS finally features [PipeWire][9] for the handling of audio/video. This should result in **a better and more secure media handling experience** across the operating system.
|
||||
|
||||
### 🛠️ Other Changes and Improvements
|
||||
|
||||
Other than that, here are some changes that are worth noting:
|
||||
|
||||
* Better **keyboard layout switching**.
|
||||
* Improvements to **Qubes Builder v2**.
|
||||
* **SELinux support** in Fedora templates.
|
||||
* A new optional, **automatic clipboard clearing feature**.
|
||||
* Integration of [fwupd][10] for handling firmware updates.
|
||||
|
||||
|
||||
|
||||
I suggest you go through the [release notes][11] for a more in-depth look into the Qubes OS 4.2 release.
|
||||
|
||||
## 📥 Download Qubes OS 4.2
|
||||
|
||||
You can get this release from the [official website][12]. Just keep in mind that, Qubes OS works properly when on bare metal, and is not meant to be run on a [Virtual Machine][13].
|
||||
|
||||
[Qubes OS 4.2][12]
|
||||
|
||||
If you are new to Qubes OS, then I recommend you go through the [official documentation][14] to learn more about this distro.
|
||||
|
||||
**For existing users,** you can follow the official [upgrade guide][15] to upgrade from Qubes OS 4.1 to 4.2.
