# Release 57: config and provisioning
|
||||
|
||||
This branch carries the work of hq design 57 (ADR 0348, ADR 0349) in this repository. Each package
|
||||
merges here through its own reviewed pull request; the branch reaches main as one pull request, in one
|
||||
delivery group with the branch of the same name in mesh-controller, mesh-host, mesh-sdk, mesh-catalog
|
||||
and hq, after a rehearsal in the lab. This file is deleted by the last commit before that pull request.
