ArcaOS 5.1 provides a modern OS/2 distribution, adding support for computers using the Unified Extensible Firmware Interface (UEFI) and for storage using the GUID Partition Table (GPT) format.
ArcaOS 5.1 is currently available in English, Spanish, German and Russian. In time, ArcaOS 5.1 will add translations to the following languages: Traditional Chinese, Simplified Chinese, French, Italian, Japanese, Korean, Dutch.
The focus is on running a full OS/2 implementation on bare metal, not just in virtual machines, and towards that goal we have done a considerable amount of testing on popular, industry-standard hardware. Blonde Guy is an active beta tester for Arca Noae. Look at Blonde Guy's ArcaOS 5.1 preloaded computers for examples of supported hardware.
ArcaOS 5.1.0 was released on August 26, 2023. ArcaOS 5.1.1 was released on February 16, 2023 in English, Spanish, German and Russian.

ArcaOS 5.1 Support and Maintenance subscription is a different product than ArcaOS 5.0 Support and Maintenance subscription. This is because some 5.1 content is only licensed for use with 5.1, so users who decide to wait to upgrade their licenses to 5.1 will get updates and support for 5.0 *only*. Likewise, there are components in 5.0 which will not ship with 5.1 (the current ArcaMapper GUI, for example). These updates would not be of any use to 5.1 licensees.
Arca Noae intends to continue support for 5.0 for some time. Whether that is based on the calendar (e.g., 1 or 2 years) or until the next minor release - 5.2 - comes out, is to be determined. For now, customers wishing to stick with 5.0 should know that they will be able to renew their support, download the latest 5.0.x ISO, and get driver updates just as they have been getting them.
ArcaOS 5.0 Support & Maintenance subscription provides continued access to the bug tracker and any updates to 5.0.x which are released.
