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 Mergify?

Mergify's merge queue now hunts the breaking PR by rerunning failed tests first

Mergify shipped more than a dozen changes in the last week of October. On the merge queue, failed batches now run the failing tests first in each split, stacked PRs enter the queue together, scope capacities work with Bazel, Pants and Turborepo scopes and patterns, and batch merge commits name the PRs they land. Test Engine gained Minitest, Jest and Mocha plugins and a setup path driven by a coding agent. Jinja2 expressions in configuration stopped being evaluated on October 31.

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.

Mergify's merge queue now hunts the breaking PR by rerunning failed tests first

◆ Current state

Mergify shipped more than a dozen changes in the last week of October. On the merge queue, failed batches now run the failing tests first in each split, stacked PRs enter the queue together, scope capacities work with Bazel, Pants and Turborepo scopes and patterns, and batch merge commits name the PRs they land. Test Engine gained Minitest, Jest and Mocha plugins and a setup path driven by a coding agent. Jinja2 expressions in configuration stopped being evaluated on October 31.

◆ Where it's heading

Mergify is tying its merge queue to test data: Test Engine knows which tests fail, and the queue uses that to bisect faster with less CI. Monorepo build tools and stacked PRs are now first-class queue inputs.

◆ Prediction

More queue behavior driven by Test Engine results is likely, given that Fail First and the new test plugins shipped the same week.
