Announcement to cf-dev mailing list: https://lists.cloudfoundry.org/g/cf-dev/message/9487

[stephanme]

cf-deployment v44.10.0 is the first cf-d version that was built, validated and released with CF API v2 disabled (see cloudfoundry/cf-deployment#1211).

[stephanme]

The final step of Phase 1 is to disable CF API v2 by default in cf-deployment. The plan looks like this:

1. Provide an ops file enable-v2-api.yml that can be used by operators to re-enable CF API v2 -> Add ops file to enable CF api v2 cf-deployment#1220
2. Disable CF API v2 by default by changing the default of the bosh config property cc.temporary_enable_v2 from true to false and cut a new CAPI release.
3. Ship the new CAPI release as part of a new major release for cf-deployment with prominent release notes mentioning the new ops file.

Step 2 and 3 are planned for beginning of 2025.

Heads-up @cloudfoundry/wg-leads : Step 2 (if you depend on cf-d release candidates) or latest step 3 can be a breaking change for your CI pipelines. The proper solution is not to add the ops file enable-v2-api.yml but to get rid of any remaining v2 usage, of course. But the ops file can buy you some time...
