Hi Brin, most of the time the distribution dictates the new version. However, sometimes it is forced due to issues with new versions of OpenStack and old versions of these dependencies (for example MariaDB 10.1 would fail to work with newer releases due to lack of MySQL compatibility). Newer versions usually mean new features that are useful for end users. In this case RabbitMQ 3.8 shines with its new Prometheus exporter. We generally try to avoid needless updates but still stay current enough to receive proper support from upstreams and satisfy the users. -yoctozepto On Fri, Sep 4, 2020 at 10:54 AM Brin Zhang(张百林) <zhangbailin@inspur.com> wrote:
Hi all

rabbitmq is v3.8.5, mariadb is v10.3.x when building Ussuri release
what kind of reasons are considered as rabbitmq version is changed from v3.7.10 to v3.8.5 ?

If you can provide an explanation, or key explanation, we would be very grateful.
Thanks.
