Bug Fixes

• Fixed the issue where newly added nodes in the cluster would not apply the new license after a cluster license update and would continue to use the old license.

  Sometimes the new node must start with a outdated license. e.g. use emqx-operator deployed and needed to scale up after license expired. At the time the cluster's license key already updated by API/CLI, but the new node won't use it.

修复

• 修复了集群更新 license 后，新加入的节点不会应用新 license 而是继续使用旧 license 的问题。

  有时新节点必须使用过时的 license。例如，在 license 过期后使用 emqx-operator 进行部署，并且需要扩展规模。此时，集群的 license 已经通过 API/CLI 更新，但新节点不会使用它。
