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 Apache OpenNLP?

Apache OpenNLP ships 3.0.0 final, closing a milestone track that ran since spring.

Apache OpenNLP runs three release lines: 1.9.x for Lucene and Solr 8 users, 2.5.x as the stable line, and the 3.0 track that went through six milestones. On 12 November the project tagged 3.0.0 final alongside a 2.5.13 patch, again shipping both lines on the same day. The tags carry no release notes in the feed, so what changed since 3.0.0-M6 is not visible here.

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.

A5.0

Apache OpenNLP ships 3.0.0 final, closing a milestone track that ran since spring.

◆ Current state

Apache OpenNLP runs three release lines: 1.9.x for Lucene and Solr 8 users, 2.5.x as the stable line, and the 3.0 track that went through six milestones. On 12 November the project tagged 3.0.0 final alongside a 2.5.13 patch, again shipping both lines on the same day. The tags carry no release notes in the feed, so what changed since 3.0.0-M6 is not visible here.

◆ Where it's heading

The 3.0 milestones combined security hardening (deserialization and XXE fixes, model-loading allowlists) with new text tooling such as the Unicode normalization engine and a SymSpell spell checker, while 2.5.x added RoBERTa inference through ONNX Runtime. With 3.0.0 out, the 2.5 line is likely to move to backports only, and new work should land on 3.x.

◆ Prediction

Expect a 3.0.1 patch and continued 2.5.x security backports; whether 1.9.x gets further releases is unclear from these entries.
