In June, Microsoft entered into a contract with Bristol Technology to develop a version of Bristol's porting application Wind/U (archived) to port IE for Windows to Unix. At this time Bristol also had a contract with Microsoft allowing it access to Windows source code from September 1994 to September 1997. The project was officially announced by Microsoft at the end of July 1996 that a native version of IE for "Solaris and other popular variants of UNIX" would be finished by the end of the year, which would have "equivalent functionality as that provided in Microsoft Internet Explorer 3.0", thus "delivering on its commitment to provide full-featured Web browser support on all major operating system platforms" as well as "supporting and promoting open standards, including HTML, ActiveX and Java".
