Classic to Deluxe Past Season Upgrade History

Diamond Mind is working hard to upgrade as many older Classic Past Season (CPS) databases to Deluxe Past Seaso n (DPS) editions as possible and that work is proceeding at a pace of about 3 or 4 upgraded seasons per year.

Seasons for the years 1932, 1944, 1946, 1949-53, 1956-1957 and the complete span of years between 1959 and 2022 (the last 64 years) are now available as Deluxe Past Season editions which include real-life transactions and lineups, left/right splits stats and complete fielding stats.

Other upgraded Deluxe Past Seasons to fill in the gaps for seasons for the years before 1959 and as far back as the 1920s will become available over time (Retrosheet play-by-play data now includes actual or deduced game accounts for all AL and NL games from 1921-2022).

With each updated season database requiring a number of months of laborious research, data entry and testing, it will be a few years before the work of upgrading is completed. Watch the Diamond Mind Baseball Forums for updates from DMBJim about what upgraded seasons are coming next.
