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 OpenObserve — 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.
OpenObserve 1.2.0-rc2 is a long fix list that closes a cross-tenant write gap.
OpenObserve opened its 1.2 cycle with rc1, led by metrics v2: alerts created from charts, comparisons, forecasts, formulas and Prometheus 3.x functions. rc2 is a large batch of fixes across the new surfaces, including blocking cross-tenant writes through function updates and remote destinations, scoping service graphs and alert lists to what a user may read, and polish for an On-Call module now tagged beta. Fleet, RUM, Kubernetes and synthetics views also got fixes.

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.
OpenObserve opened its 1.2 cycle with rc1, led by metrics v2: alerts created from charts, comparisons, forecasts, formulas and Prometheus 3.x functions. rc2 is a large batch of fixes across the new surfaces, including blocking cross-tenant writes through function updates and remote destinations, scoping service graphs and alert lists to what a user may read, and polish for an On-Call module now tagged beta. Fleet, RUM, Kubernetes and synthetics views also got fixes.
The 1.2 cycle is wider than metrics: rc2's fixes reveal on-call scheduling, fleet management, RUM, synthetics and incident root-cause features heading into the release. Several fixes tighten tenant and permission boundaries, which suggests multi-tenant and enterprise deployments are a priority before 1.2 goes stable.
Expect one more release candidate or a 1.2.0 stable soon, followed by 1.2.x backport patches as the 1.1 line had.
