8.X line is considered experimental through May of 2024. Releases are being made for testing on significant changes. Migration aids will be published in Feb 2024 to assist in tracking the API and XSD breaking changes. The 8.X release is aimed at migrating away from XSD and towards protobufs, but that is still a work in progress. Users should differ to the last release of the 7.X line if stability is a concern.
