What happened: Version 3.1 reorders clubs by roster need as front offices make their final buy-or-sell decisions. Players on major-league contracts cannot be traded after the deadline.

Why it matters: The update supersedes the July 8 edition, reflecting how late moves and shifting races have changed priorities. Deadline acquisitions can reshape postseason rosters for the stretch run.

What to watch: Watch for completed trades before the 6 p.m. ET cutoff.
