What is Jaeger?

Jaeger folds its MCP server into the query service and drops Elasticsearch 6

Jaeger's 2.x line is releasing roughly monthly, and two threads dominate. The storage layer is being modernised and pruned — Elasticsearch 6 support removed, rotation and index-cleaner feature gates promoted to beta, ClickHouse gaining TLS and analyzer fixes, configurable max trace duration. The other thread is the query surface: a lightweight trace-summaries endpoint added in 2.19 then given a native Elasticsearch implementation in 2.20, and the MCP extension merged into the query extension.

What is Tolgee?

Tolgee ships four patch releases in a day, mostly security bumps and branching fixes.

Tolgee released 3.239.1 through 3.240.3 between October 24 and 26: eMudhra roots removed from the Java trust store, Spring Boot and Hibernate security bumps, faster branch creation, Slack integration fixes, and a usage estimate that now includes one-time upgrade proration. Just before, 3.238.0 reverted per-organization plan feature grants.

Jaeger folds its MCP server into the query service and drops Elasticsearch 6

◆ Current state

Jaeger's 2.x line is releasing roughly monthly, and two threads dominate. The storage layer is being modernised and pruned — Elasticsearch 6 support removed, rotation and index-cleaner feature gates promoted to beta, ClickHouse gaining TLS and analyzer fixes, configurable max trace duration. The other thread is the query surface: a lightweight trace-summaries endpoint added in 2.19 then given a native Elasticsearch implementation in 2.20, and the MCP extension merged into the query extension.

◆ Where it's heading

Jaeger is treating machine consumption of traces as a first-class query path rather than an add-on. Merging jaegermcp into jaegerquery means the MCP surface ships wherever query ships, and trace summaries give both the UI and any agent a cheap way to scan results before pulling full traces. On storage, the direction is fewer supported backends maintained better, with ClickHouse steadily gaining parity.

◆ Prediction

Expect the trace-summaries path to become the default for search across storage backends, and further ClickHouse feature work as the Elasticsearch surface is trimmed rather than extended.

5.0

Tolgee ships four patch releases in a day, mostly security bumps and branching fixes.

◆ Current state

Tolgee released 3.239.1 through 3.240.3 between October 24 and 26: eMudhra roots removed from the Java trust store, Spring Boot and Hibernate security bumps, faster branch creation, Slack integration fixes, and a usage estimate that now includes one-time upgrade proration. Just before, 3.238.0 reverted per-organization plan feature grants.

◆ Where it's heading

Tolgee ships from main almost daily. The visible themes are billing accuracy (proration, plural machine translation billing, the reverted feature grants), branching performance, and quick upstream security updates.

◆ Prediction

Expect the per-organization feature grants to return in a reworked form, alongside more billing and branching fixes.
