## Changes

### KMSCon user-space Linux Console feature

This set of unstable updates was dominated by trying to land KMSCon and enabling it by default.

However, we learned rather quickly that this would cause undesirable behaviour in the form of hi-jacking the visible display output, meaning the user would be presented with a KMSCon VT instead of the active display manager with no obvious way to switch back (CTRL+ALT+F1 would usually, but not always, work).

Therefore, we have decided to not enable KMSCon by default until this issue has been sorted out. This coincided with the Christmas holidays, so unearthing and corroborating the undesirable behaviour, and subsequently figuring out what a good next step might look like, took a bit longer than we anticipated.

### Declarative moss system-model export and import tech preview features

Moss now has the ability to use a declarative `/etc/moss/system-model.kdl` to define installed packages and repositories.

In addition, for users who prefer the classic “imperative” moss experience, it is now possible to `moss state --export` a `system-model.kdl` file of the current system to share with others.

In turn, it is also possible to one-shot `moss sync --import` an existing `system-model.kdl` file.

These features are delivered as a tech preview.

### Boulder package recipe version string requirements

The Boulder packaging tool now checks for a valid recipe version string (= anything starting with an integer) and errors out if the version string is not valid.

This is necessary because our `ent` package update checking tool compares version strings to determine whether packages need an update, and will give false positives if we have a version string that looks like e.g. `v0.1.2` (note the `v`).

### Highlights

- KDE Frameworks 6.21.0
- KMSCon 9.2.1 (currently not enabled by default)
- NVIDIA graphics driver 590.48.01

### Fixes

### Security Fixes:

- Patches to networkmanager and networkmanager-openvpn for CVE-2025-9615

### New packages
