- version release features
- ------- ------- --------
- OS/2 1.0 Dec '87 essentially a protected-mode 286 version of DOS
- with multiple threads, multiple processes, etc.
- and can run one conventional DOS session.
-
- OS/2 1.1 Nov '88 added Presentation Manager and Desktop Manager shell.
-
- OS/2 1.2 late 89 added High-Performance File System (HPFS),
- DOS session had a little more memory.
-
- (split?) Sep '90 IBM and MS "announced a change in their development
- relationship" [_The Design of OS/2_, pg 17]. This
- means IBM was to take care of OS/2 1.x and OS/2 2.x,
- while MS was to take care of OS/2 3.0 . I don't
- know if this is the IBM-MS split, or if it happened
- later when MS announced OS/2 3.0 / Portable OS/2 /
- OS/2 NT / whatever will become Windows NT instead
- by using the Windows-style API instead of PM.
-
- OS/2 1.3 Oct '90 faster, and used less RAM space.
-
- OS/2 2.0 Mar '92 386 version, multiple DOS and Windows 2.x/3.0 processes,
- much better DOS support (EMS, XMS, DPMI, settings, etc.)
- Workplace Shell (WPS) replaced Desktop Manager, and in
- Oct '92 the 32-bit graphics engine replaced the hybrid
- one.
-
- OS/2 2.1 ??? '92 Windows 3.1 support, some other stuff???
