OpenBSD 2.2 released (Dec 4, 1997)

This is a partial list of the major machine independent changes (i.e., these are the changes people ask about most often). Machine specific changes have also been made, and are sometimes mentioned in the pages for the specific platforms if you are interested in further port-specific details. Many ports have had architecture-specific enhancements relative to NetBSD, but when they do not they certainly have plenty of platform-independent changes, starting with those listed below..

Note: Problems for which patches exist are marked in red.

Changes made between OpenBSD 2.1 and 2.2
