While IBM’s OS/2 technically did die, its development was picked up again much later, first through eComStation, and later, after money issues at its parent company Mensys, through ArcaOS. eComStation development stalled because of the money issues and has been dead for years; ArcaOS picked up where it left off and has been making steady progress since its first release in 2017. Regardless, the developers behind both projects develop OS/2 under license from IBM, but it’s unclear just how much they can change or alter, and what the terms of the agreement are.
Anyway, ArcaOS 5.1.2 has just been released, and it seems to be a rather minor release. It further refines ArcaOS’ support for UEFI and GPT-based disks, the tentpole feature of ArcaOS 5.1 which allows the operating system to be installed on a much more modern systems without having to fiddle with BIOS compatibility modes. Looking at the list of changes, there’s the usual list of updated components from both Arca Noae and the wider OS/2 community. You’ll find the latest versions of of the Panorama graphics drivers, ACPI, USB, and NVMe drivers, improved localisation, newer versions of the VNC server and viewer, and much more.
If you have an active Support & Maintenance subscription for ArcaOS 5.1, this update is free, and it’s also available at discounted prices as upgrades for earlier versions. A brand new copy of ArcaOS 5.1.x will set you back $139, which isn’t cheap, but considering this price is probably a consequence of what must be some onerous licensing terms and other agreements with IBM, I doubt there’s much Arca Noae can do about it.
