In our continuing commitment to ArcaOS 5.0 (Blue Lion), Arca Noae is pleased to announce the general availability of ArcaOS 5.0.8, the eighth maintenance release of the 5.0 line.

It should be noted that ArcaOS 5.1.0, the successor to the 5.0 line, is nearing availability. While ArcaOS 5.1.0 itself is ready, the production system which manages, builds, and distributes the new ISO images is not. However, the final testing of our updated production system is underway and nearing completion. In the interim, we are releasing ArcaOS 5.0.8 which can be distributed using the old production and distribution system.

ArcaOS 5.0.8 includes refreshed driver content, updated kernel and included software, as well as installation boot fixes since 5.0.7 was released at the end of 2021. It also rolls in a few fixes that come from our 5.1.0 development work. ArcaOS 5.0.8 can be used for new installs or to update any prior version of ArcaOS 5. If you have experienced difficulty installing previous releases of ArcaOS on your hardware, 5.0.8 may address your issue(s). 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.

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 update is included with your valid ArcaOS 5.0 Support & Maintenance subscription at no additional charge. To download your fresh ISO, simply visit your customer portal page and select the ArcaOS Download Center link on the navigation panel to the left.

Also, your active ArcaOS 5.0 subscription will entitle you to a discount on your ArcaOS 5.1 upgrade purchase, when available.

ArcaOS 5.0.5 introduces support for xHCI (USB3) controllers to install on a wider array of systems than ever before.

USB3-attached keyboards and mice should work, as well.

ArcaOS 5.0.5 includes over 100 updates, enhancements, and fixes since 5.0.4 was released. If you have experienced difficulty installing previous releases of ArcaOS on your hardware, the fixes and updates included in 5.0.5 may address your issue(s).

After nearly a year of development and testing, Arca Noae is proud to announce the general availability of ArcaOS 5.0.4, the fourth maintenance release of ArcaOS 5.0 (Blue Lion).

ArcaOS 5.0.4 introduces a new Updater feature, allowing all previous ArcaOS installations to be brought up to the current codebase by simply booting from the installation medium, selecting the new Update option on the Installation Type page, and finally the target system volume to be updated. The resulting system is essentially what a fresh install would be, without losing settings, other installed programs, application data, and having to reconfigure the environment from scratch.

ArcaOS 5.0.4 includes well over 100 updates and fixes since 5.0.3. The USB stick image package has also been updated to incorporate the latest changes in ArcaOS 5.0.4 and is now personalized, delivered in the same archive as the ISO itself, and may be created using any major operating system at hand (Windows, Linux, MacOS, and of course, OS/2, eComStation, and ArcaOS). Once the image is restored, eject, re-insert, and simply copy your ISO to the stick per the included directions (also detailed in the ArcaOS support wiki). The stick may then be inserted into any USB 2.0-controlled port in the target system, and used to boot into the ArcaOS installer/updater.

Systems originally installed from DVD may be updated using the AltBoot (USB stick) method, and systems originally installed from USB stick may be updated from DVD; the choice is yours.

If you have experienced difficulty installing previous releases of ArcaOS on your hardware, the fixes and updates included in 5.0.4 may address your issue(s). ArcaOS 5.0.4 includes a major update to the installation boot component, making it easier than ever to boot and install on systems with non-standard memory configurations.

Arca Noae is pleased to announce the immediate availability of ArcaOS 5.0.3, the third maintenance release of ArcaOS 5.0 (Blue Lion).

ArcaOS 5.0.3 is (again) the result of many hours of collaborative work to keep up-to-date and to further refine ArcaOS 5.0. Post-install fixes are included, and these will be made available for separate download as part of the ArcaOS 5.0 Support & Maintenance subscription. In the interim, a full download of the refreshed media image is required to obtain all of these fixes and updates.

ArcaOS 5.0.3 includes over 40 updates and fixes since 5.0.2. The USB stick image package (available as a separate download for ArcaOS licensees with current support and maintenance subscription) has also been updated to incorporate the latest changes in ArcaOS 5.0.3.

A bootable ArcaOS 5.0.3 USB stick may be created from any major operating system at hand (Windows, Linux, MacOS, and of course, OS/2, eComStation, and ArcaOS). Once the image is restored, eject, re-insert, and simply copy your personalized ISO (separately downloaded) to the stick per the included directions (also detailed in the ArcaOS support wiki). The stick may then be inserted into any USB 2.0-controlled port in the target system, and used to boot into the ArcaOS installer.

If everything is working in your current installation, it may be prudent to wait for the subscription content to become available, as Arca Noae has not classified any of the 5.0.3 updates as critical.

If you have experienced difficulty installing ArcaOS 5.0.2, the fixes and updates included in 5.0.3 may address your issue(s).
