As of the next major release of Arbortext Publishing Engine, the 6.0 release, PTC is planning to support the Windows platform only.
PTC Will Discontinue Arbortext Publishing Engine Support on the Linux and Solaris Operating Systems with the Release of Arbortext Publishing Engine 6.0
Having reviewed customer product downloads and technical support submissions over the past four years, PTC has seen low adoption of Arbortext Publishing Engine running on non-Windows platforms. As a result, PTC is planning to support Windows only with the 6.0 release of Arbortext Publishing Engine. In addition, PTC has no plans to introduce support for Solaris on x86 platforms.
Arbortext Publishing Engine 5.4, including all of its maintenance releases, will continue to be supported on Windows, Solaris, and Linux platforms per the Arbortext 5.4 Software Compatibility Matrix.
We recognize that discontinuing support for Arbortext Publishing Engine on the Linux and Solaris platforms may be disruptive to some of our customers who plan to upgrade to future releases. Therefore, PTC is committed to providing an acceptable migration path to all Arbortext Publishing Engine customers currently running on the Linux or Solaris platform.
