What is Gloo Gateway?

Gloo Gateway's October batch fixes proxies that silently kept stale endpoints.

Gloo Gateway still maintains 1.19, 1.20 and 1.21 in parallel and releases them in same-day batches. The 2026-10-21 batch fixes a bug where a placeholder EDS assignment carried the wrong cluster name, so a proxy received an update it could not match, kept its old endpoints and never recovered. Each line also moved to Go 1.26.10; 1.21 additionally upgraded kin-openapi.

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.

Gloo Gateway vs Jaeger: editorial side-by-side

5.0

Gloo Gateway's October batch fixes proxies that silently kept stale endpoints.

◆ Current state

Gloo Gateway still maintains 1.19, 1.20 and 1.21 in parallel and releases them in same-day batches. The 2026-10-21 batch fixes a bug where a placeholder EDS assignment carried the wrong cluster name, so a proxy received an update it could not match, kept its old endpoints and never recovered. Each line also moved to Go 1.26.10; 1.21 additionally upgraded kin-openapi.

◆ Where it's heading

Releases remain maintenance: Go and Kubernetes bumps on a weekly rhythm, with an occasional real bug fix shipped to every line at once. The 1.18 line no longer appears in the October batches. No new features are visible.

◆ Prediction

Expect further same-day dependency batches across the three lines; the entries show no feature release coming.

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.
