desktop multimedia support. Updated versions of various bundled components, both IBM and non-IBM, were also included. eComStation 1.2 was released in English, German and Dutch NLVs. Version 1.2 media refresh (1.2R) Serenity Systems announced its intention to provide a "media refresh" incorporating a number of fixes and updates which had been made available after the release of eComStation 1.2. This was released as version 1.2R, initially on November 12, 2005, but subsequently withdrawn and re-released (due to a last-minute bug fix) on November 17, 2005. The principal new feature of eComStation 1.2R was support for installation on Athlon 64 systems, which had previously required unsupported workarounds. eComStation 1.2R was released in English, German, and Italian NLVs. Additionally, a beta release of a Traditional Chinese NLV was made available via download for registered customers. Version 2.0 eComStation 2.0 had a longer-than-usual development cycle. The first beta was released on December 21, 2005, with the first "release candidate" being announced on June 18, 2007; the final GA release was not available until May 2010. The biggest change in eComStation 2.0 was the addition of ACPI support, which represented the first major update to the core operating system to be developed specifically for eComStation (and not by IBM). The benefits of ACPI included support for modern hardware, including advanced power-management features, as well as support for IRQs above 15. In addition, the new ACPI driver allowed access to OS/2's symmetric multi-processing support, obviating the need for IBM's proprietary SMP-enablement driver. Consequently, starting with eComStation 2.0, SMP support was included in the base product at no additional cost. The other major feature introduced in version 2.0 was an enhanced version of the Journaled File System which allowed the operating system to be booted directly from JFS-formatted partitions. (Previous versions of JFS had only been usable on non-bootable data partitions.) Installing the operating system onto JFS allowed a significant performance improvement, due to the much larger cache sizes supported by JFS, as well as reduced CHKDSK times in the event of a non-clean shutdown. The eComStation pricing model was revamped significantly with version 2.0. The standard consumer version was the Home & Student Edition. This edition had a lower recommended retail price than previous versions of eComStation; however, one customer was limited to five purchases. The Business Edition was targeted at commercial customers, with no limit on the number of purchases. The Business Edition also
