Apache NiFi 0.4.1 发布，主要更新如下：
- Bugs addressed
- Site-To-Site: If the remote system was applying back-pressure and the sending system attempted to stop the connection the sending system flow configuration could hang. If one of the nodes in a cluster being delivered to went off-line it could cause site-to-site to stop delivering to the other nodes in certain conditions. The automatic account request mechanism was broken.
- Flow File Ordering: Ordering based on timestamp of flow file entry has been augmented with a sequence counter to provide better ordering precision.
- Run duration: Only shown now when the processor supports the batching mechanism of run duration.
