Eight platform-agnostic manual traffic source dimensions
'…user-scoped, session-scoped, and event-scoped variations of 8 new platform-agnostic traffic source dimensions… apply consistently across paid and organic traffic and across Google media and third-party media.'
Source: What's new archive — Feb 8, 2024.
What it breaks
Nothing breaks; older 'session source / medium' dimensions coexist and can disagree with the manual ones.
Who it hits: Anyone building channel reports.
The fix
Standardise on one family of dimensions per report (the audit's second check).

Source group and UTM audit checklist
The checks that keep channel reports honest through Google's dimension changes: the Google tag before custom events, one family of traffic-source dimensions per report, Source Group vs raw source, the primary channel group frozen and documented.
