48.0.0 (2022-10-05)

Support for VPC SSM parameters has been removed.
You will need to migrate to guardian/aws-account-setup instead.
See the migration section below for more info on how to do this.

Account setup, including VPC parameters is now done via:

and it is sensible to only manage these in a single place.

As a reminder, the parameters are typically:

/account/vpc/primary/subnets/public
/account/vpc/primary/subnets/private

('primary' may differ if you have overridden the prefix here.)

There is unfortunately no way to transfer Cloudformation
ownership of SSM parameters.

Therefore, to migrate you will need to:

raise a PR to add your account to
https://github.com/guardian/aws-account-setup but do not merge yet
raise a PR bump guardian/cdk to latest in your projects that use
the GuVpc constructor but do not merge yet
pause all Cloudformation deployments that use the VPC-related
SSM parameters for that VPC
merge and deploy (2) - this will delete your existing parameters
merge and deploy (1) - this will recreate them via aws-account-setup
unpause any deployments from (3)

'pause' in (3) is probably best achieved by adding temporary RR
deployment restrictions. See:
