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 Routinator?

Routinator 0.16 will validate ASPA and BGPsec, and run strict, by default

Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. After a run of security work, including an external audit's four CVEs in 0.15.2 and resource-exhaustion fixes in 0.15.3, 0.16.0-rc1 changes defaults: ASPA and BGPsec are on, strict validation is on, and the old enable flags become --disable-aspa, --disable-bgpsec and --relaxed. It also adds Resource Signed Checklists (RFC 9323), SLURM v2 with ASPA filtering, and a new repository logging scheme that changes the /status JSON.

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.

Routinator 0.16 will validate ASPA and BGPsec, and run strict, by default

◆ Current state

Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. After a run of security work, including an external audit's four CVEs in 0.15.2 and resource-exhaustion fixes in 0.15.3, 0.16.0-rc1 changes defaults: ASPA and BGPsec are on, strict validation is on, and the old enable flags become --disable-aspa, --disable-bgpsec and --relaxed. It also adds Resource Signed Checklists (RFC 9323), SLURM v2 with ASPA filtering, and a new repository logging scheme that changes the /status JSON.

◆ Where it's heading

Having spent 2026 hardening the validator, the maintainers are now changing what operators get out of the box. Defaults moving toward ASPA and strictness put newer RPKI object types on equal footing with route origin validation.

◆ Prediction

A final 0.16.0 following one or more release candidates is the likely next step, as with 0.15.0.
