OPENSTEP 4.2 Developer Release Notes:
An Introduction 

With every release of its software, NeXT provides notes containing information pertaining to the release. These notes apply to Releases 4.2 and 4.1, and in some cases to earlier releases as well. 

These on-line Release Notes list new features, fixed bugs, and known bugs that will be of interest to developers using OPENSTEPä for Mach, OPENSTEP Enterprise, and PDO. These notes are as complete and up-to-date as we could make them at the time the CD-ROM was manufactured. We continue to incorporate information about the release, discovered since manufacture, into the release notes. These updated notes can be obtained from NeXTanswers. For the location of the most up-to-date release notes for this or any other NeXT product, request NeXTanswer #2455.

About This Release

Release 4.2 is primarily a bug-fix release. In addition, numerous fixes and enhancements have been made to the development tools, and the compilers have been synched-up so that they use the same source base across NeXT's entire product line (OPENSTEP for Mach, OPENSTEP Enterprise, and PDO).  Release 4.2 also supports Windows 95 as a deployment platform (debugging is supported, but compilation is not).

The various files containing release notes for developers are listed below.  These files are included in the ªDeveloper Release Notesº target of the NEXTSTEP Developer bookshelf (in the directory /NextLibrary/Bookshelves), and are located in /NextLibrary/Documentation/NextDev/ReleaseNotes.
