Warpstock Europe 2025

Come join us at Warpstock Europe 2025 this weekend!

If you’ve never attended a Warpstock or Warpstock Europe event, these are truly unique and enjoyable experiences. This weekend, in Amersfoort, The Netherlands, Arca Noae Managing Member, Lewis Rosenthal, and Chief UI Architect, Alex Taylor will be on hand to present and answer questions regarding ArcaOS past, present, and future.

It’s not too late to register for the event. Visit the Warpstock Europe homepage for more information and to purchase tickets.

Lewis will provide the latest roadmap for ArcaOS 5.1, including highlights of development and planning for the 5.1.2 release. Alex will be discussing what it takes to create a localized ArcaOS version, and for developers, how to write or update existing applications to take advantage of some of the newer dynamic font sizing support in ArcaOS.

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.

Arca Noae turns 10

Very quietly on July 28, Arca Noae, LLC marked its tenth year since its founding in 2014. On this occasion, we at Arca Noae would just like to take a moment to thank our valued customers, clients, and fans for their business, continued dedication to the OS/2 platform, and for their love of ArcaOS, from the warm reception we received at our humble beginnings to the overwhelming excitement at the initial release of ArcaOS Blue Lion nearly three years later, in 2017, and right up through our current versions and updates.

Last year, we released ArcaOS 5.1, which has been a major milestone in OS/2 history, as the first version capable of installing and booting on modern UEFI-based systems without the aid of a Compatibility Support Module (CSM), and the first version to be able to utilize GPT partitioned storage devices.

Today, we stand on the cusp of delivering ArcaOS 5.1.1, which promises to be the first ArcaOS version available in languages other than English, and is slated to include many fixes and enhancements to the installation process for 5.1.

Our continuing mission is to provide support for modern hardware on the OS/2 platform, to make ArcaOS easier to use and more functional for daily computing needs for home users, small-medium sized businesses, and enterprise customers. In that, we see no end in sight.

Thanks for traveling with us on our journey.

Clearing up some more upgrade confusion: Subscription downloads

It’s important to remember that when an ArcaOS 5.0 license is upgraded, the existing ArcaOS 5.0 license is converted to an ArcaOS 5.1 license. This does not create a new license for another system. If the ArcaOS 5.0 license has a Support & Maintenance subscription in effect, any remaining time is added to the ArcaOS 5.1 subscription. Several actions take place automatically on Arca Noae’s side of the transaction and other actions should take place on the customer’s side.

First, on the Arca Noae side:

  1. The existing ArcaOS 5.0 Support & Maintenance subscription for that license is terminated as of the date of the upgrade of its associated license to ArcaOS 5.1.
  2. With the termination of the ArcaOS 5.0 Support & Maintenance, access to associated downloads for ArcaOS 5.0 is removed If you have more than one ArcaOS 5.0 license with current support and are only upgrading one of those licenses to 5.1, the associated downloads will still be available for your other ArcaOS 5.0 licenses.
  3. Whatever time was left on the ArcaOS 5.0 Support & Maintenance subscription is added to the included subscription for ArcaOS 5.1. So, if you recently renewed your 5.0 subscription, and it had 12 months before the next renewal, your new ArcaOS 5.1 personal license will now have 18 months of support & updates (6 months from the new ArcaOS 5.1 subscription plus the remaining 12 months from the old ArcaOS 5.0 subscription). You don’t lose anything.

On the customer side, the installation of the ArcaOS 5.0 license being upgraded should be upgraded to ArcaOS 5.1. It is a violation of our license terms to upgrade a 5.0 license to 5.1, install the 5.1 license on another system or partition, and to continue using the 5.0 installation. One license is consumed per bootable installation, regardless of the edition (personal or commercial). If that license has been upgraded, the upgraded license is only valid for the upgraded ArcaOS version. An upgrade does not create a new license for another installation.

If you would like to maintain access to ArcaOS 5.0 downloadable content, but would also like to install ArcaOS 5.1, then we invite you to purchase a new ArcaOS 5.1 license from our store or from your preferred authorized reseller. In that case, the two subscriptions will be separate, and their contents will be available in your ArcaOS Download Center as long as the respective subscription remains in force.
