Jaeger vs WPML: at a glance
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 WPML?
WPML made machine translation the default, and its point releases keep chasing WordPress and page builders.
The shipping 4.9 line is compatibility work: WordPress 7.1 support with a security hardening pass in the newest release, PHP 8.5 compatibility and a smoother site-migration flow before that, and WordPress 7.0's iframe-based block editor before that. The 5.0 beta running in parallel is the larger move — a redesigned interface, a simplified translation engine, and automatic translation switched on by default for new sites.

◆ 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.

WPML made machine translation the default, and its point releases keep chasing WordPress and page builders.
◆ Current state
The shipping 4.9 line is compatibility work: WordPress 7.1 support with a security hardening pass in the newest release, PHP 8.5 compatibility and a smoother site-migration flow before that, and WordPress 7.0's iframe-based block editor before that. The 5.0 beta running in parallel is the larger move — a redesigned interface, a simplified translation engine, and automatic translation switched on by default for new sites.
◆ Where it's heading
Two clocks again. The maintenance clock is dictated entirely by other people's releases: WordPress majors, PHP versions, Divi 5, Elementor. Enough of this feed is compatibility that it reads as the real cost of being a translation layer inside someone else's ecosystem. The product clock points one direction, toward automation — cost and time estimates before sending content, one-click recovery for stuck jobs, automatic detection of custom Elementor widgets, and now automatic translation as the starting state rather than an option. The 4.9.7 security hardening is worth noting alongside a beta in flight: the stable line still gets real attention.
◆ Prediction
Expect the 5.0 line to move from beta to production with the automatic-first defaults intact, followed by continued compatibility maintenance as WordPress core and major builders evolve.
