What is Jaeger?

Jaeger's query service learns to search individual spans, not just whole traces.

Jaeger 2.21 and 2.22 extend the 2.x storage and query rework. ClickHouse storage moved to a stable feature gate in 2.21, and the release removed v1 HTTP endpoints the UI no longer calls. In 2.22 the query service gains FindSpans with RFC 0014 pagination, Elasticsearch span search, and structured filters promoted to beta, while native Elasticsearch trace summaries go stable.

What is Rancher?

Three Rancher branches went from rc1 to final in a day, with nothing but a Dashboard ref bump.

Rancher's latest round cut v2.11.19, v2.12.15 and v2.13.11 as finals on October 29, one day after their rc1 tags. Each tag body shows only the automated Dashboard ref update. Alongside them, v2.15.3 reached rc2 and v2.14.7 reached rc1, so the two newest lines are still in candidate stage.

Jaeger vs Rancher: editorial side-by-side

2.5

Jaeger's query service learns to search individual spans, not just whole traces.

◆ Current state

Jaeger 2.21 and 2.22 extend the 2.x storage and query rework. ClickHouse storage moved to a stable feature gate in 2.21, and the release removed v1 HTTP endpoints the UI no longer calls. In 2.22 the query service gains FindSpans with RFC 0014 pagination, Elasticsearch span search, and structured filters promoted to beta, while native Elasticsearch trace summaries go stable.

◆ Where it's heading

The earlier trace-summaries work made search cheaper; span search changes what can be asked. Pagination and structured filters give both the UI and MCP clients a way to query without pulling whole traces. MCP keeps getting practical limits and input checks, and search_traces no longer needs a service name on backends that declare support for that.

◆ Prediction

Expect span search to spread beyond Elasticsearch and memory storage, and structured filters to move from beta to stable as other gates have. Further removal of v1 surface is likely, since 2.21 already started it.

5.0

Three Rancher branches went from rc1 to final in a day, with nothing but a Dashboard ref bump.

◆ Current state

Rancher's latest round cut v2.11.19, v2.12.15 and v2.13.11 as finals on October 29, one day after their rc1 tags. Each tag body shows only the automated Dashboard ref update. Alongside them, v2.15.3 reached rc2 and v2.14.7 reached rc1, so the two newest lines are still in candidate stage.

◆ Where it's heading

The feed keeps publishing the branch matrix rather than what shipped in it. The older branches move through quickly on automation while the newest lines take extra candidates, the same split as the August round. What changed in these releases is not visible in the entries, so the pattern shows process rather than product direction.

◆ Prediction

Expect v2.15.3 and v2.14.7 finals to follow once their candidates clear. Nothing in these tags indicates what they contain.
