OS/2 Warp Version 4

The OS/2 V4 desktop

The fourth major release of the client version of the OS/2 operating system and also known as Warp 4 or under the original project name Merlin. It is not as radical a change as OS/2 Warp Version 3 was from OS/2 Version 2 mainly because the money earmarked for OS/2 development inside IBM's Personal Systems Division was used to develop the ill-fated OS/2 PPC, and while small portions of the OS/2 PPC code showed up in Merlin, most of the changes were superficial. The release does include a number of additional features that were developed as separate programs though, such as OpenGL support.

Versions

Minor versions

IBM released versions 4.5 for those with a defect support contract and for a time also sold it as a upgrade. This has numerous fixes and updates introduced in OS/2 Warp Server for e-business, and a small number of fixes developed since. The last minor version released was 4.52
