The FreeDOS Beta 3 "Ventura" distribution was released 22 April 1999.
Codename
Jim lived in Minnesota, and the state had then recently elected former WWE wrestler Jesse Ventura as governor the previous Fall, assumed office 4 January 1999. From Jim: "By April, he'd probably done something really dumb, and for whatever reason I memorialized it in the Beta 3 codename. (Note: I did not vote for Ventura.)"
History
This Wayback snapshot shows a news item dated 22 Apr 1999 for Beta 3. Install instructions are dated 21 Apr 1999, but there's another news item that the updated kernel was worth delaying Beta 3 to include it, so assume the install instructions were written ahead of time and the release made on 22 Apr 1999.
