This Oracle Solaris 11.4 release is dedicated with great appreciation to the memory of UNIX pioneer Roger Faulkner (1940-2016).

Roger worked at Bell Labs from 1976 until 1990, where he co-created the /proc file system, and was a leader and mentor in Solaris engineering from the time he joined Sun Microsystems in 1990 until his passing. Every single release of Solaris from Sun Solaris 2.0 through Oracle Solaris 11.4 has included Roger’s work, and we are proud to publish his final changes in this release.

Diversity and Inclusion

Oracle is fully committed to diversity and inclusion. Oracle respects and values having a diverse workforce that increases thought leadership and innovation. As part of our initiative to build a more inclusive culture that positively impacts our employees, customers and partners we are working to remove insensitive terms from our products and documentation. We are also mindful of the necessity to maintain compatibility with our customers' existing technologies and the need to ensure continuity of service as Oracle's offerings and industry standards evolve. Because of these technical constraints, our effort to remove insensitive terms is ongoing and will take time and external cooperation.
