5.3 Post-Oracle closed source (March 2010 to present).5.1 Traditional operating system license (1982 to 2004).Solaris is developed under a proprietary development model, and only the source for open-source components of Solaris 11 is available for download from Oracle. Through the Oracle Technology Network (OTN), industry partners can gain access to the in-development Solaris source code. In 2011, the Solaris 11 kernel source code leaked to BitTorrent. Following that, OpenSolaris was forked as illumos and is alive through several illumos distributions. In August 2010, Oracle discontinued providing public updates to the source code of the Solaris kernel, effectively turning Solaris 11 back into a closed source proprietary operating system. After the acquisition of Sun Microsystems in January 2010, Oracle decided to discontinue the OpenSolaris distribution and the development model. With OpenSolaris, Sun wanted to build a developer and user community around the software. In June 2005, Sun Microsystems released most of the codebase under the CDDL license, and founded the OpenSolaris open-source project. Historically, Solaris was developed as proprietary software. Solaris was registered as compliant with UNIX 03 until 29 April 2019. Solaris supports SPARC and x86-64 workstations and servers from Oracle and other vendors. Solaris is known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider. In 2010, after the Sun acquisition by Oracle, it was renamed Oracle Solaris. It superseded the company's earlier SunOS in 1993. Oracle Solaris (formerly known as Solaris) is a proprietary Unix operating system originally developed by Sun Microsystems.
