What is deal.II?

deal.II ships one big finite-element release a year, then patches it twice

deal.II is on a steady annual major-release rhythm — 9.6 in late 2024, 9.7 in July 2025, 9.8 in August 2026 — with one or two bug-fix point releases filling each gap. Its GitHub release notes are deliberately thin: each one links out to a generated changes-between-versions page and spends its body on contributor credits. What the feed does show directly is the shape of the project, including a release-candidate train that runs about two weeks before each major.

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.

deal.II ships one big finite-element release a year, then patches it twice

◆ Current state

deal.II is on a steady annual major-release rhythm — 9.6 in late 2024, 9.7 in July 2025, 9.8 in August 2026 — with one or two bug-fix point releases filling each gap. Its GitHub release notes are deliberately thin: each one links out to a generated changes-between-versions page and spends its body on contributor credits. What the feed does show directly is the shape of the project, including a release-candidate train that runs about two weeks before each major.

◆ Where it's heading

The contributor roster is the signal these notes carry best, and it is growing: 9.8.0 alone credits roughly two dozen first-time contributors against a recurring core of about sixty. Point releases stay narrow and mechanical — MSVC and C++20 compatibility, MatrixFree face handling, Trilinos/Tpetra fixes — which suggests release engineering is stable enough that regressions surface in a predictable band. Nothing in the feed indicates a change of direction; this is a mature library compounding.

◆ Prediction

Based on the 9.6 and 9.7 patterns, expect a 9.8.1 within roughly two months carrying compiler-compatibility and MatrixFree fixes, and the next major in mid-2027 preceded by a short rc1-through-rc4 train. The release notes themselves are unlikely to get more detailed given how consistently they defer to the external changelog.

M6.3

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.
