MT-SRE is requesting that teams begin using a folder-based organization over branching:

 
During CY22Q3, CPaaS is transitioning from using branches to manage product versions to using folders in a single branch for that purpose.
 
We would like to encourage all products onboarded to CPaaS to conclude their migration to folder-based repos early on, in order to enjoy new automation features which require using folders (for example, automatically creating new Z-stream versions).
 
 
Migrating takes several minutes, and is described in this doc, recording, slides.

 
Please reach out for support to the "CPaaS Users" Google Chat channel in case anything is needed.
