UNIX/TS Release 4 was a major release of the USG UNIX/TS line in the Bell System in 1981. Unlike the prior and following versions which were released as System III and System V respectively, there was no external release of this version as UNIX System IV.
Many of the changes which were first encountered outside of the Bell System in UNIX System V truly had their start in Release 4. Examples of such features which originated in Release 4:
- The Common Object File Format (COFF)
- The LP Print System
- Semaphores, Shared Memory, and Message Handling (IPC) matching System V introduced in 4.1
- The SGS (System Generation Software)
Note: This is material that is, as of this typing, being actively uncovered and investigated, so this content will be in flux as time goes on.
