A side-by-side editorial comparison of Graphite and Apache StreamPark — release velocity, themes, recent moves, and the top alternatives to consider.
Graphite's answer to its own CVE backlog is a pre-release nobody calls official.
Graphite's release feed shows three entries across four years. The last tagged work is a pair of 1.2.1 pre-releases whose own notes decline to call them official: they exist, in the maintainer's words, as a master-branch milestone for people who want to avoid CVE checks against 1.1.x, with the second adding XSS fixes. Both point at a single open discussion thread about the state of the project.
Five release candidates in two years, none of them stable, and none since October 2025.
StreamPark's tracked feed holds five release candidates spanning April 2024 to October 2025, and the notes are extremely thin — three of the five describe a single change each, one of them a Vue router naming bug. The most substantial entry, v2.1.7-rc1, lists four items: Maven argument validation, a license header consistency fix, a login authentication refinement and a Flink configuration file retrieval fix. No stable release appears anywhere in this record.

This is a project whose maintenance and its release process have come apart. The security fixes are real and are in master, but nothing has been promoted to a release users can adopt through normal channels, which leaves operators choosing between a version that fails CVE scans and an explicitly unofficial tag. The four-year gap since the 1.1.9 preparation commit is the clearest signal available.
Nothing in these entries supports a confident call on a 1.2.1 final; the maintainer has pointed the question at a discussion thread rather than a roadmap.

No stable release appears anywhere in this record.
Nothing in these entries describes new capability for the stream processing platform itself. The changes cluster around build tooling, authentication and the web console — the periphery of the product rather than its Flink and Spark job management core. Combined with a cadence of roughly two releases a year and a nine-month gap since the last one, the visible signal is a project in low-activity maintenance.
The entries do not support a prediction about direction. What they do warrant is checking whether development moved somewhere this feed does not capture, since a stream processing platform with no stable releases on record is more likely a tracking gap than a complete picture.
