Winter '27 just gave Flow the safety net it's needed for years.

I walked through all seven updates in the new release — dedicated Test Mode, save-time error catches for missing fields and field length, bulk actions from any list view, locked-down permissions, faster version comparisons, and one-click cleanup of unused resources. 

They fall into three buckets:  

✨ build-time safety nets,  

✨ runtime and access control, and  

✨ workspace hygiene  

— and I go through live demos of each. 

My one habit-change recommendation:  

Turn on Flow Test Mode on your next new flow before you activate it.  

It's the single thing that'll save you the most debugging time.
