Dynamic Icons version 2.5.6 for ArcaOS released

Dynamic IconsDynamic 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.
