Scalar is testing demand for hosting from inside localhost
A side-by-side editorial comparison of Jaeger and YARA — release velocity, themes, recent moves, and the top alternatives to consider.
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.
YARA 4.6.0 is the first minor in two years, and it is almost entirely bounds checks.
4.6.0 is YARA's first minor release since 4.5.0 in September 2024. It adds yr_get_version, nine more e_machine values in the elf module and a man-page sync; everything else is bug fixes across compiled-rule loading, the regex engine, the VM, ELF handling and Authenticode. Loading a compiled rule file now validates indices, external variables, arena buffers and Aho-Corasick states. The release credits Ada Logics and Anthropic among its contributors.

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.
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.

The parser-under-pressure reading holds, with wider scope. Earlier patches bounded single values; this release treats compiled rules and regex input as hostile throughout. Fixes for exponential growth on nested regex repeats and infinite loops show the review now covers resource exhaustion as well as corruption.
Expect 4.6.x patches in the same files, since this list is long and contributor-driven. Nothing here signals new language features; the three additions are small.
