Version 1.15.0

Version 1.15.0 of Apache NiFi is a significant feature, improvement, and bug fix release.

Release Date: TBD - Release Candidate Voting in progress now

Highlights of the 1.15.0 release include:

Parameter Contexts now support inheritance. This makes it far easier to manage common sets of properties used across many flows and tweak only specific parameters as needed for a given instance. This pattern is super common and valuable for NiFi users that run many instances of the same flow or versions of a flow.
NiFi's API now allows components to offer a validation mechanism focused on talking to external services and surfacing that back through the REST API and NiFi UI. Why is that awesome? Well NiFi was always great with validation but sometimes when talking to an external service like Kafka you couldn't tell if things were going to work until you ran it. Now for components that leverage this feature, like the Kafka processors, we can validate that the topic at play exists and is accessible. There are a lot of powerful uses of this which will make building and understanding flows easier.
Stateless NiFi is extremely powerful and more engines to execute it in are emerging. In the meantime though a powerful option is to run Stateless NiFi flows inside of a traditional NiFi deployment. You can use such a thing then to support Kafka flows with exactly once semantics while enjoying the powerful benefits of NiFi at the same time.
The shockingly popular scripted record processors support highly customizable routing and partitioning.
