Engert. A number of features from OS/2 Warp 4 which IBM had omitted from the Convenience Package release, such as voice navigation and dictation, System improvements developed by Serenity itself including a new installer, various user interface enhancements, system configuration changes, and a rapid deployment system based on Serenity Managed Client. Open source utilities from the Unix world. A number of small utilities and drivers developed by various third parties. As IBM began to wind down OS/2 development, Serenity and its partners began to take up the slack (through a combination of in-house, contract, and community/open source development efforts) in terms of keeping the operating system usable on current hardware. The results of many of these efforts are included in version 2 of eComStation; among others: ACPI support. A new generic graphic card driver called Panorama. A bootable version of JFS. A 'universal' sound card driver based on ALSA. AHCI support (introduced in version 2.1). On-the-fly resizing of hard drive partitions. A new client to access CIFS/SMB (Windows-style) LAN resources (supporting both files and printers) based upon Samba. Ports of current Mozilla Firefox and Mozilla Thunderbird for browsing and email. A port of the OpenOffice.org office suite. A server version of eComStation is available, which is based on IBM OS/2 Warp Server for e-business (WSeB) 4.52. It includes the same set of software bundled with WSeB, which includes the IBM WebSphere Application Server, and the Lotus Domino Go Webserver. History Origins When it became clear that IBM would not release any new retail version of the OS/2 Warp client operating system after version 4 in 1996, users began to consider other alternatives. IBM released a final version of its server edition, IBM OS/2 Warp Server for e-Business or WSeB, internally called version 4.5. IBM also continued updating the client and merged parts of it with the server, so it was proposed by Bob St. John of Serenity Systems, that an OEM company could and should create its own client, using the existing OS/2 client with IBM enhancements and adding its own improvements where needed. But Serenity as an IBM business partner had done a similar thing with OS/2-based vertical applications like the Serenity Managed Client, a rapid deployment OS based on Workspace On-Demand, and Ecomstation Server, a managed server based on WSeB. The OS/2 software vendor Stardock made such a proposal to IBM in 1999, but it was not followed
