Release 4.0 was launched from this organization in March. It introduced new IPC mechanisms as well as new drivers and changes to the text processing software and the C libraries etc. Also in March, the first UNIX release for an IBM machine was launched as UNIX/370 Release 3.0" Pirzada, A Statistical Examination of The Evolution of the UNIX System https://spiral.imperial.ac.uk/bitstream/10044/1/7942/1/Shamim_Sharfuddin_Pirzada-1988-PhD-Thesis.pdf
