ANALYTICS
Velocity0.0

Distributed tracing system for microservice latency analysis

zipkin.io ↗

Zipkin's last release was January 2025 — a dependency bump, and then nothing.

◆Current state
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.
◆Where it's heading
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.
◆Prediction
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.

    Zipkin 3.4

    OpenSearch v2 becomes a supported storage backend, reusing the same ES_-prefixed environment variables as Elasticsearch so existing deployments can switch without new configuration. The last release in this feed to add a capability.
