  • UI now shows when all data in a queue is penalized, and the processor will no longer run millions of times per minute in order to accomplish nothing
  • MiNiFi Java can now hot-load nars just like NiFi.
  • Tons of bug fixes and improvements for processors that interact with cloud services on AWS, Azure, and GCP as well as SFTP, FTP, Kafka and more.
  • Stateless NiFi getting better and better with improved classloader isolation and ability to run off local nars only.
  • Security: Aggressively update libraries such as Jetty, Netty, Logging related libs (log4j, slf4j, etc..), and moved to latest H2 Database to eliminate any worries about a vulnerability in the older line.  Included a super slick mechanism to upgrade from the old database to the new one without the user having to worry about it.
  • Resolved CVE-2022-26850 - Insufficiently Protected Credentials in Single User Login Identity Provider
