Reminder: Warpstock Europe 2026, Amersfoort, The Netherlands, June 5-7

The OS/2 VOICE Foundation will be hosting Warpstock Europe 2026 June 5-7 in Amersfoort, The Netherlands.

VOICE is planning to provide a live video stream via YouTube, but the best Warpstock Europe experience is always in person.

Time is running short to register for Warpstock Europe, however! To register, use this link before May 25. For more information (travel, schedule of presentations, presenters, and more) please visit the Warpstock Europe website.

Don’t miss out on this fantastic opportunity to see, hear, and meet with people directly and indirectly involved with shaping the design and focus of ArcaOS, and working to keep it connected to our ever-changing landscape of information technology. Connect with your peers. There is always great fun and conversation, as well as in-dpeth technical stuff and great user-to-user exchanges.

We hear there will be another fun social outing on Saturday this year, too!

ArcaOS 5.1.2 now available

Arca Noae is proud to announce the general availability of ArcaOS 5.1.2 in English, German, Spanish, and Russian.

ArcaOS 5.1.2 improves the support for installation on the latest generation of UEFI-based systems, as well as the ability to install to GPT-based disk layouts. This enables ArcaOS 5.1.2 to install on a wide array of modern hardware. As with all ArcaOS releases, ArcaOS 5.1.2 still boots, installs, and runs well on traditional BIOS-based systems, offering enhanced stability and performance for either environment.

This release is free of charge to those with active ArcaOS 5.1 Support & Maintenance subscriptions, and there is no charge for requesting additional language ISOs (though your total number of ArcaOS 5.1 installations may not exceed the number of ArcaOS 5.1 licenses you have).

ArcaOS 5.1.2 can be used for new installs or to upgrade any prior English version of ArcaOS 5. If installing from USB stick, the USB install stick may be created using any major operating system at hand (Windows, Linux, MacOS, and of course, OS/2, eComStation, and ArcaOS). Once built, the USB stick can be inserted into any USB port in the target system to boot into the ArcaOS installer/updater in either UEFI or traditional BIOS mode (alternatively, the DVD image may be burned to physical media and also booted to either UEFI or traditional BIOS systems). See the wiki for specific notes and limitations of the USB stick creation utility on Windows.

For a complete list of updates in this release, see the ArcaOS wiki. Be sure to review the README.TXT, as well, as this contains critical information to ensure that you get up and running fast, and includes tips for getting things adjusted right away.

This upgrade is available at a steep discount with your valid ArcaOS 5.0 Support & Maintenance subscription (and your remaining subscription time will be added to the included support term). To download your fresh ISO, simply visit your customer portal page and select the Download Center link on the navigation panel to the left. From there, click the “Upgrade to 5.1” button, and proceed to checkout.

If your ArcaOS 5.0 Support & Maintenance subscription has already expired, you may still upgrade at less than the cost of a new ArcaOS 5.1 license. Follow the procedure above to order your upgrade, and the discount will be reflected in your cart.

New ArcaOS 5.1.2 license purchases are initially built as English. To request a different language, simply visit your Download Center, select the Build ISO Again button, and choose your language.

Need more convincing? How about a commercial operating system which doesn’t spy on you, does not report your online activity to anyone, and gives you complete freedom to choose the applications you want to use, however you want to use them? How about an operating system which isn’t tied to any specific hardware manufacturer, allowing you to choose the platform which is right for you, and fits perfectly well in systems with less than 4GB of memory or even virtual machines?

Arca Noae is committed to continuing the development, support, maintenance, and refinement of the OS/2 platform. The next release of ArcaOS is indeed already in the works. The future continues to look bright for Arca Noae and ArcaOS!

Major website migration complete

To address unanticipated changes forced upon us by functional components used by our website and online store, we have migrated the main Arca Noae site to a different server on our network. We hope this solves the most pressing issues regarding site availability, performance, and checkout completion.

Meanwhile, this migration brings with it some changes to procedures, namely, population of subscription content lists in the Download and Renewal Center. The new process will refresh content for all subscribers over a longer period of time vs on-demand download of fresh driver packages (as an example). The change should be fairly transparent to the end user (when a download link is displayed, it will be functional, as before), but note that there may be some delay between the announcement of new or updated content and downloads actually being listed. We are continuing to work to improve this feature.

For all those who have experienced difficulty with renewals, for a limited time, we have extended the normal grace period to one full year before the late renewal fee is applied. This should give everyone ample time to renew his or her ArcaOS Support & Maintenance subscription(s) without concern. This is a limited time offer, however, so if you have been holding off on a renewal due to site frustrations, please do so now at your earliest convenience.

Website issues impacting new and renewal orders

Our most recent website updates (mandatory, for security reasons) seem to have led to some instabilities. We have worked to manage the situation while we continue to solve the underlying problem(s). In the interim, customers may experience intervals of exceptional slowness on the site and there is a potential for failed payment processing.

We apologize for the inconvenience. If your order fails to process, please try again.

Meanwhile, we believe we have solved the issue with renewal orders not properly displaying the required credit card input fields for payment. Renewal orders should add the renewal to the cart and land on the Shop page. From there, proceed to checkout. If you find that your link has taken you to the checkout page directly, select the link there to visit your shopping cart, then use the Proceed to checkout button (or use the Renew button for your subscription from your Download Center).

At times, changes to our website are forced upon us by the software developers, generally in response to a security concern. It is impossible to predict how an update to one facet of the site may impact something else. We do our best to handle these situations when they arise, and appreciate your patience.

The Download Center is now the Download & Renewal Center

In January of 2023, we introduced the ArcaOS Download Center. After expanding this download center to include all subscriptions and their associated downloads, we renamed it simply the Download Center. However, because this portal has so much more functionality which may not be apparent without visiting it first, we have again modified the name to the Download & Renewal Center.

If you are not familiar with this handy tool, in the left navigation area you should see the Download & Renewal Center link. Clicking it will bring you to a consolidated listing of your ArcaOS licenses and associated downloads followed by your other subscriptions and their associated downloads. Need a new ISO? No problem. Just find your ArcaOS license with active support, and request a new one. In addition, no matter which type of subscription you have, you’ll be able to see at a glance when the subscription is set to expire, and have the ability to simply click a button to renew a subscription. That’s it!

So, if you are using an email client or web mail which for some reason does not properly provide you with a usable link in your renewal reminder email, simply visit your Download & Renewal Center, select the license with expiring support, and click Renew.

Dynamic Icons version 2.5.6 for ArcaOS released

Dynamic Icons has been updated to version 2.5.6, and is now available as part of the Support & Maintenance subscription for your ArcaOS product. Please log into your account and see your ArcaOS order details page to access your software. This update is available for 5.0 and 5.1 ArcaOS licensees with active Support & Maintenance.

Version 2.5.6 introduces a new caching scheme which essentially eliminates duplicated icons, significantly reducing memory overhead and dramatically improves desktop responsiveness. In addition, it is now possible to specify different icon size parameters for Tree and Icon views, a longstanding and often requested enhancement.

For those who rely on Dynamic Icons, this update is a must-have.

Many, many thanks to Rich Walsh for his hard work on this update.

If you are still running OS/2 and/or eComStation systems and haven’t yet moved up to ArcaOS, this is a great reason to do so now. If you’ve already made the switch, but haven’t renewed renewed your support subscription, this is also a good time. Not sure what’s coming next? Have a look at our product roadmap pages.

Why update or upgrade to ArcaOS 5.1.1?

If you’re holding off upgrading from ArcaOS 5.0 to 5.1 or updating from 5.1.0 to 5.1.1, here are a few things to consder to get you off the fence.

ArcaOS 5.1.1, over a year and a half in development, incorporates over 50 improvements and refinements, from smoother installation and better integration with other operating systems to better stability and usability of the system. Here are a few points to consider from the changelog:

Now available in four languages (with more on the way): English, German, Spanish, and Russian. More comfortable computing in your native language? This is all made easier with ArcaOS 5.1.1.
For existing English installations, upgrading from 5.0 or updating from 5.1.0 could not be easier. Back up your system, boot from the installation media, select the option to update/upgrade, and select your existing installation from the list. The rest of the procedure is automatic.
Multimedia support has been upgraded and enhanced. Not only has the multimedia subsystem been translated to the system language, but if you have a CD collection and a modern PC, ArcaOS now handles digital transfers and supports the GnuDB CD track identification database.
Both remote control of the ArcaOS system and control of other systems from ArcaOS has been greatly enhanced with a new VNC server and client, supporting features found in UltraVNC, such as chat, file transfer, and encryption for web clients.
Of course we’ve also included the latest ACPI and updated device drivers for USB, video, mouse (new, major revision), FAT32 filesystem (for better interoperability and data exchange with other operating systems), and even a new keyboard driver for better operation on more hardware.

In short, 5.1.1 is the most stable, best performing ArcaOS release to date, and provides a truly modern OS/2 computing experience for PCs. It’s also quite at home in a virtual environment, running under Oracle VirtualBox or VMware ESXi or Workstation.

Best of all, for ArcaOS 5.1 licensees with active support subscriptions, the update from 5.1.0 to 5.1.1 is absolutely free. Let your subscription lapse? You can still renew and get the 5.1.1 release for no additional charge. Still running 5.0? Now is a great time to take advantage of the steep upgrade discounts offered to upgraders.

ArcaOS 5.1.1 now available

Arca Noae is proud to announce the general availability of ArcaOS 5.1.1 in English, German, Spanish, and Russian.

ArcaOS 5.1.1 continues to support installation on the latest generation of UEFI-based systems, as well as the ability to install to GPT-based disk layouts. This enables ArcaOS 5.1.1 to install on a wide array of modern hardware. Of course, ArcaOS 5.1.1 is just as much at home on traditional BIOS-based systems, offering enhanced stability and performance across both environments.

ArcaOS 5.1.1 can be used for new installs or to upgrade any prior English version of ArcaOS 5. If installing from USB stick, the USB install stick may be created using any major operating system at hand (Windows, Linux, MacOS, and of course, OS/2, eComStation, and ArcaOS). Once built, the USB stick can be inserted into any USB port in the target system to boot into the ArcaOS installer/updater in either UEFI or traditional BIOS mode (alternatively, the DVD image may be burned to physical media and also booted to either UEFI or traditional BIOS systems).

New ArcaOS 5.1.1 license purchases are initially built as English. To request a different language, simply visit your Download Center, select the Build ISO Again button, and choose your language.

Arca Noae is committed to continuing the development, support, maintenance, and refinement of the OS/2 platform. The next release of ArcaOS is already in the works. The future looks bright for Arca Noae and ArcaOS!

ArcaOS named Best Alternative OS of 2025 by TechRadar!

It is always gratifying to receive acclaim from our peers and the educated press. It seems that TechRadar has listed ArcaOS as #1 in their list of Best alternative operating systems of 2025, albeit with some slight misstatements in their overview (which we have brought to their attention).

One of the points which is specifically incorrect is the negative notion that ArcaOS is “for older PCs.” ArcaOS 5.1 should install on many or most new or recent Intel or AMD-based hardware. It is capable of booting on UEFI-only systems, without the aid of a CSM, using our proprietary 64-bit UEFI loader, and then booting ArcaOS (which itself is 32-bit) just as it would on a traditional BIOS system.

ArcaOS 5.1 also supports booting from GPT partitioned media, making it a great companion OS for multiboot configurations where the disk (or SSD) has already been partitioned this way and where it may be impractical to wipe and convert to MBR-style partitioning.

In fact, it is also something to note that ArcaOS is specifically not intended for use on “older” hardware, such as ISA, EISA, or MicroChannel, as most of the device drivers for those architectures were removed from ArcaOS prior to its initial release.

Another misstatement in the article pertained to pricing which quoted figures for licensing of the 5.0 release which itself is no longer available (though support for 5.0 continues with no stated EOL). Also, if you already have an ArcaOS 5.0 license, generous upgrade discounts apply should you want to move up to ArcaOS 5.1.
