Preface: A Short History of DB2 for z/OS

Version 1 Release 1 was announced on June 7, 1983. And it became generally available on Tuesday, April 2, 1985. I wonder if it was ready on April 1st but not released because of April Fool’s Day?

Version 1 Release 2 was announced on February 4, 1986 and was released for general availability a month later on March 7, 1986. Wow! Can you imagine waiting only a month for a new release ...
