Manticore Search vs Undertow
A side-by-side editorial comparison of Manticore Search and Undertow — release velocity, themes, recent moves, and the top alternatives to consider.
Manticore Search vs Undertow: at a glance
What is Manticore Search?
Three patch releases in eight hours: Manticore's 29.0 line is being stabilized in public.
Manticore shipped 29.0.3, 29.0.4 and 29.0.5 inside a single day, three days after the 29.0.2 release notes consolidated the sharding work. Two are correctness fixes in query handling — internal sort helper columns leaking into LEFT JOIN output, and NEAR and proximity distances being reset by repeated JSON query fixup. The third hardens the binary API against malformed search counts under a reported advisory.
What is Undertow?
Undertow 2.4.0 clears three CVEs and finally lands long-open HTTP/2 and timeout requests
Undertow's 2.4 line opened in May 2026 with a release that combines three CVE fixes with a backlog of feature requests, several of them years old judging by their issue numbers — in-flight request processing time tracking, comments in the predicate language, a configurable async context timeout replacing a hard-coded one, HTTP/2 GOAWAY connection management, a TLS protocol version exchange attribute, and a method to invalidate all cache paths. The two releases since have been small: a handful of Jiras in 2.4.1, and a 2.4.2 whose entire release note is the sentence that it was tagged.

Manticore Search
6.3DEVOPS
Three patch releases in eight hours: Manticore's 29.0 line is being stabilized in public.
◆ Current state
Manticore shipped 29.0.3, 29.0.4 and 29.0.5 inside a single day, three days after the 29.0.2 release notes consolidated the sharding work. Two are correctness fixes in query handling — internal sort helper columns leaking into LEFT JOIN output, and NEAR and proximity distances being reset by repeated JSON query fixup. The third hardens the binary API against malformed search counts under a reported advisory.
◆ Where it's heading
The pattern after a major line opens is holding: the commit-level train keeps running at multiple releases a day while the newly exposed surfaces — sharded tables, LEFT JOIN, JSON query parsing — report their edge cases back. The bugs being caught are shaped by what 29.0 changed rather than by new work, and each one arrives with regression coverage attached, which is why they land as separate patch releases rather than accumulating. Search-side work continues to split between classic full-text concerns and the vector and conversational paths.
◆ Prediction
The patch cadence should keep compressing toward the ordinary rhythm as the 29.0 edge cases drain; the next substantive item is more likely to come from the columnar and KNN thread than from sharding, which has just had its release.
Undertow

Undertow 2.4.0 clears three CVEs and finally lands long-open HTTP/2 and timeout requests
◆ Current state
Undertow's 2.4 line opened in May 2026 with a release that combines three CVE fixes with a backlog of feature requests, several of them years old judging by their issue numbers — in-flight request processing time tracking, comments in the predicate language, a configurable async context timeout replacing a hard-coded one, HTTP/2 GOAWAY connection management, a TLS protocol version exchange attribute, and a method to invalidate all cache paths. The two releases since have been small: a handful of Jiras in 2.4.1, and a 2.4.2 whose entire release note is the sentence that it was tagged.
◆ Where it's heading
The 2.4.0 pattern — a long-deferred feature backlog shipping in the same release as security fixes — suggests features move when a release has to happen anyway rather than on their own schedule. What did ship points at operational control: timeouts that were hard-coded becoming configurable, connection lifecycle handling for HTTP/2, and attributes exposing TLS and timing detail to whatever sits above the server. Enabling test runs on JDK 25 in 2.4.1 is the only forward-looking item in the two follow-up releases.
◆ Prediction
With three entries and one substantive release among them, there is little to extrapolate from; the JDK 25 test enablement is the one thread that implies more work, pointing at runtime compatibility rather than features as the near-term focus.
