Team, With the release of NiFi 1.19.0 deprecating support for Java 8, the end of the year provides a good opportunity for finalizing general release goals for NiFi 2.0.
Based on previous discussions from July 2021 [1] and June 2022 [2], there seems to be general agreement with focusing a NiFi 2.0 release on reducing technical debt while providing a straightforward upgrade path for current deployments. I have updated the NiFi 2.0 Proposed Release Goals [3] to reflect more recent progress in several areas. I also linked the Deprecated Components and Features [4] page outlining the current state of deprecated capabilities. The most recent update to the Proposed Release Goals outlines implementing migration tooling to make the upgrade process as easy as possible. The addition of dedicated deprecation logging in NiFi 1.18.0 makes it easier to warn of breaking changes, but the goal of migration tooling is to make it easier to upgrade configurations. The Proposed Release Goals does not include any release timelines right now, and we should anticipate supporting version 1 for a reasonable period of time. As more and more libraries deprecate and drop support for Java 8, it will become increasingly difficult to maintain a support branch, which is one of the main drivers behind a NiFi 2.0 release that drops support for Java 8. The general development strategy should involve transitioning the main branch to a 2.0.0-SNAPSHOT version so new features and fixes will be targeted to the new version. Migration tooling will need to be implemented on a version 1 support branch, and fixes can be backported where possible, in preparation for subsequent version 1 releases. With that background, I would like to move to a formal vote soon, changing the Proposed Release Goals document to Planned Release Goals. Please weigh the general goals highlighted, and if there are no major roadblocks identified, I will follow up soon with a vote thread.
