Version 5.2 introduces support for HP-UX 11i v2 and HP-UX 11i v3 on HP Integrity servers with Intel Itanium 64-bit processors, and HP-UX 11i v3 on HP 9000 servers with PA-RISC processors, as well as Red Hat Enterprise Linux 5 for x86_64 and SUSE Linux Enterprise Server 10 for x86.

"UNIX servers will continue to hold their place in the data center as customers trust the security, availability, and reliability that UNIX provides," said Brian Cox, director, Software Planning and Marketing, Business Critical Systems, HP. "The ability to port C++ applications onto HP-UX 11i v2 and v3 through Mainsoft for UNIX's technology will further help customers run mission-critical applications in the best possible system environment."
