Graphite
Graphite's answer to its own CVE backlog is a pre-release nobody calls official.
A side-by-side editorial comparison of Apache StreamPark and OpenCTI — release velocity, themes, recent moves, and the top alternatives to consider.
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.
OpenCTI is turning its connector catalog into a marketplace with a support tier attached.
OpenCTI ships on a roughly weekly cadence, and the last six releases mix steady platform work — saved searches, dashboard filters, workflow governance — with a consistent push on how connectors are discovered and supported. The catalog became a faceted marketplace in late July, connectors are now labelled as supported by Filigran or by the community, and several releases wire the platform into Filigran's XTM Hub. The notes themselves are dense PR lists with no narrative, so the direction has to be read off what keeps recurring.

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.

The recurring thread is commercial structure around an open-source core. Enterprise Edition gating on workflow restrictions, a catalog that distinguishes vendor-supported connectors from community ones, and repeated XTM Hub integration all point the same way: the platform stays open while the ecosystem and its support tiers become the thing being sold. Underneath that, the workflow subsystem keeps maturing through draft approval, auto-save, reset and restore, which suggests adoption by teams that need review gates before intelligence is published.
Expect more of the catalog to organize around the supported-versus-community distinction, and the draft approval workflow to pick up the permission and audit controls that the recent RBAC and audit-log work is laying groundwork for.
