Heads up: cflinuxfs4 rollout in cf-deployment

Jochen Ehret

Dear CF Developers,
we'd like to share with you the rollout plan of cflinuxfs4 in cf-deployment [1].
The current cflinuxfs3 stack is based on Ubuntu Bionic and will reach end of life in April 2023 [2]. We will replace it with the Jammy-based cflinuxfs4 stack when all buildpacks are available. We are still waiting for the php- and staticfile-buildpacks. The status is summarized in [3].
Step 1 (when all buildpacks are available): We will publish a cf-deployment release with cflinuxfs4 as the default stack. The cflinuxfs3 stack will still be available and we will provide an ops file to revert to fs3 as the default.
Step 2 (latest in April): We will remove the cflinuxfs3 stack and buildpacks. An ops file to add the (unmaintained) fs3 components back will be provided.
Both releases will be cut as incompatible major releases.
