New Zenwalk Release Features Linux 7.1 and Xfce 4.20

On September 5, 2026, a testing release of Zenwalk, the Slackware-based Linux distribution, was published. It is named Zenwalk Current Milestone 2026. It is a milestone update coming more than four years after the previous generation, Zenwalk 15.0. It is now available for weekend testing.

According to reporting by Michael Larabel at Phoronix, the key points of this release are clearly laid out. It builds on the existing Slackware upstream with Zenwalk-specific improvements. The default kernel is Linux 7.1. It combines it with the BORE scheduler aimed at reducing latency. The desktop environment is based on Xfce 4.20. Another feature is the distribution-wide integration of Flatpak support.

The original text reads as follows.

It’s been over four years since the original release of Zenwalk 15.0 while released today is a new Zenwalk Current Milestone snapshot.

This single sentence sums up its positioning as a restart after four years. Details on how to obtain it are available on Zenwalk.org.

Background and Positioning of Zenwalk’s Revival

Zenwalk is a distribution with a long history as a Slackware derivative. Slackware 15.0 was released in February 2022. Zenwalk 15 followed in its wake. Since then, no major milestone releases had been published. This Current Milestone is a testing release that fills that gap.

The design philosophy of Current Milestone is clear. It incorporates the latest Slackware upstream. It then adds Zenwalk’s own system improvements. It also refines the desktop experience at the same time. It aims to combine a conservative base with a modern feel.

Phoronix had already covered Zenwalk back in 2006. Even then, it was known as a lightweight and responsive distribution. It inherited Slackware’s simple design. It included adjustments that made it easier for beginners to use. This update continues that lineage.

Slackware-based systems change slowly. They have been supported by users who prioritize stability. On the other hand, the freshness of application software remained a challenge. Current Milestone addresses this structure. It is an attempt to broaden the user base while maintaining upstream robustness.

Significance of Adopting Linux 7.1 and BORE

The default kernel is Linux 7.1. It is one of the major kernel series in the second half of 2026. The same kernel series is also used in Amazon Linux 2027 Preview Released with Linux 7.1. Improved hardware support and security are expected. As a base refresh, it is highly significant.

A highlight is the adoption of the BORE scheduler. BORE is a scheduling mechanism aimed at improving responsiveness. It focuses on reducing latency for interactive operations. The Zenwalk developers have been working on low-latency improvements since last month. This time, those results are reflected in the default configuration.

Slackware-based systems traditionally favor a simple configuration. Changes to the scheduling mechanism have been handled cautiously. Even so, smooth responsiveness is important for desktop use. For video playback and audio processing, latency directly affects the perceived experience. In development work, too, the quality of input response affects productivity.

The adoption of BORE demonstrates a desktop-focused approach. It differs in direction from tuning for server use. It is a choice that puts everyday comfort first. It is now at the stage of confirming its effectiveness in a testing release for evaluation. Reports from users will influence future tuning.

Updating the kernel and scheduler also affects maintenance. A custom scheduler increases follow-up work. Keeping pace with upstream updates will be a challenge. A testing framework in the testing release is important. Adoption for production use should be decided after assessing the results.

Aim and Effects of Full Flatpak Integration

The biggest change this time is the full integration of Flatpak. Application installation via Flatpak is supported across the distribution. It can be used alongside traditional Slackware-style management. Users gain more choices for obtaining software.

Slackware has kept automatic dependency resolution to a minimum. It is a philosophy that values system transparency and simplicity. This philosophy has been highly appreciated by advanced users. On the other hand, installing new applications took effort. Adjusting individual dependencies burdened users.

Flatpak is a mechanism for distributing applications in containers. It bundles and isolates the necessary runtime environment. It is less affected by differences in the base system. It makes it easier for developers to deliver the latest applications. It allows users to simplify installation procedures.

Full integration is significant. It is not merely an additional installation method. It is designed for use from the initial state. It also ties in with enhanced multimedia support. It helps ensure codec and playback environments.

It could also change the character of the distribution. The separation between a conservative base and a new application layer will advance. The base can be kept stable while applications can be updated quickly. This two-layer structure has become established in recent distribution design. Zenwalk can be seen as having joined that trend.

Xfce 4.20 and Desktop Refresh

The desktop environment is based on Xfce 4.20. Xfce is a lightweight desktop environment with low resource consumption. It runs without becoming sluggish even on older computers. Its traditional workflow is easy to learn. It pairs well with stability-oriented distributions.

This update includes desktop-related improvements. A new graphical system management tool has been added. System status and settings can be handled graphically. It reduces the burden on users unfamiliar with the command line. It serves as an entry point for administrative tasks.

Improved multimedia support is also highlighted. Audio and video playback environments have been prepared. Installation of codecs has become smoother. Integration with playback software via Flatpak is also effective. Fewer issues are expected in daily use.

Other minor changes are also included. Artwork and user experience have been refined. Modernization to fill the long gap has been carried out. It is presented as the desktop image for 2026. The screen layout remains simple.

Demand for lightweight desktops remains strong. A resource-efficient configuration is also advantageous in virtual environments. It is suitable for development machines and media playback terminals. The adoption of Xfce 4.20 is a solid choice. It prioritizes sustained use over flashiness.

Installation Notes and How to Obtain It

Current Milestone is positioned as a testing release. It is not intended as a replacement for daily use. It is intended for weekend testing and evaluation. Bug reports will help development. It is safer to wait for a stable release before full deployment.

It is available via Zenwalk.org. ISO images are provided. Trying it in a virtual machine is also effective. If installing on physical hardware, a backup is essential. Important data must be copied in advance.

Operating Slackware-based systems has its own conventions. There are many cases where configuration files are edited directly. Users accustomed to automated tools may be confused. It is safer to proceed while consulting documentation and records. The graphical management tool can be used as an aid.

There are also caveats for using Flatpak. Containerized applications tend to consume disk space. This is because runtimes are duplicated. Check your network connection and available storage. It is advisable to limit installation to necessary applications.

Note also the use of a custom scheduler in the kernel. Hardware behavior may differ. In particular, power-saving and wireless-related behavior should be checked. If problems occur, switching configurations can be considered. Sharing test results will help the distribution mature.

Editorial Opinion

In the short term, we see reactions to the testing release setting the direction for development. The effectiveness of responsiveness improvements from BORE will be the focus of testing. The completeness of the Flatpak integration will also directly affect user evaluations. The Slackware user base has strict standards for quality. Reports over the next three to six months will determine the pace of stabilization. It may be re-evaluated as a lightweight desktop option.

In the long term, we assess that balancing a conservative base with a modern application layer will be the challenge. A two-layer structure — keeping the base stable while delivering applications quickly via containers — is becoming established. Zenwalk can be said to be a case that fits that structure. On a one- to three-year timescale, the burden of maintaining a custom scheduler will be questioned. Balancing upstream tracking with responsiveness tuning will determine sustainability. Maintaining a small development team will be key.

The remaining issue is the division of roles between Flatpak and native formats. If dependence on containers advances, will the simplicity of the system be diminished? Which layers should the graphical management tool cover? For which tasks will the effects of BORE be most noticeable? As editors, we believe accumulated test reports and a clear statement of design philosophy are needed. The balance between expanding the user base and preserving tradition is at stake.
