OpenMetadata
OpenMetadata 2.0.8 widens Hex, Sigma and BigQuery coverage while 2.1 waits in release candidates.
A side-by-side editorial comparison of Zipkin and Kubecost — release velocity, themes, recent moves, and the top alternatives to consider.
Zipkin's last release was January 2025 — a dependency bump, and then nothing.
The recent history is three consecutive maintenance releases whose entire content is dependency and base-image updates: 3.4.3 aligned Maven versions with the Docker images, 3.4.2 and 3.4.1 moved Spring Boot, Netty, Micrometer, Armeria, Alpine and the JRE forward to clear CVEs. The last release carrying a feature was 3.4 in May 2024, which added OpenSearch v2 as a storage backend using the existing ES_-prefixed environment variables.
Kubecost cuts three 3.3.2 release candidates in two days, still without notes.
Kubecost opened the 3.3.2 patch line on November 11 and tagged rc.1 through rc.3 by November 13. Each is an automated in-code version bump with no described changes, as with every tag since October, when the 3.3.1 and 3.2.5 candidates went out the same way.

This is a project in preservation rather than development. The pattern across the window — feature in May 2024, then three releases of purely defensive dependency work, then silence since January 2025 — describes a mature tracing server being kept safe to run rather than extended. The distributed-tracing work that would once have landed here now largely happens in OpenTelemetry, which Zipkin interoperates with rather than competes against.
The feed has produced nothing for nineteen months, so the honest read is that no next release is scheduled. If one comes, the shape of the last three says it will be another dependency and base-image refresh rather than new capability.

The quick run of candidates suggests 3.3.2 is close to a final tag. The public tags still say nothing about what the patch fixes.
Expect a 3.3.2 final tag within days; what it changes will not be visible from these release notes.
