Brent Ozar notes some problems:
SQL Server 2025 Cumulative Update 1 came out last week, and I was kinda confused by the release notes. They described a couple dozen fixed issues, and the list seemed really short for a CU1.
However, the more I dug into it, the weirder things got. For example, there were several new DMVs added – which is normally a pretty big deal, something to be celebrated in the release notes – but they weren’t mentioned in the release notes. One of the DMVs wasn’t even documented. So I didn’t blog to tell you about CU1, dear reader, because something about it seemed fishy.
Read on for a big deal.
