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.

Best Regards,

  Jochen.
