In 1995, work began to enhance the file system to be more scalable and to support machines that had more than one processor. Another goal was to have a more portable file system, capable of running on multiple operating systems. After several years of designing, coding, and testing, the new JFS was first shipped in OS/2 Warp Server for eBusiness in April 1999, and then in OS/2 Warp Client in October 2000. In December 1999, a snapshot of the original OS/2 JFS source was granted to the open source community and work was begun to port JFS to Linux. The first stable release of "JFS for Linux" appeared in June 2001. The "JFS for Linux" project is maintained by a small group of contributors known as the "JFS Core Team". This release of sources also worked to form the basis of a re-port back to OS/2 of the open-source JFS.
