If there are any planned API/ABI change on v19.02, deprecation notice patches for them should be sent, approved and merged withing v18.11 scope which is only a few days away.
If you will be working on a feature for v19.02, please take some time think if it will cause any API/ABI change. And if it will so, please send the deprecation notice for it ASAP, otherwise your feature can be blocked for the release because of API/ABI breakage it causes. Thanks, ferruh
