deal.II vs SimpleSAMLphp: at a glance
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 SimpleSAMLphp?
SimpleSAMLphp advances two maintenance branches in lockstep, security patches first.
SimpleSAMLphp is maintaining the 2.4 and 2.5 lines in parallel and patching both from the same fixes. Six releases since late May split into two security releases — the 2.4.6/2.5.1 pair on 29 May and 2.5.3 on 10 August — and four bugfix releases. Release bodies carry only download links and SHA256 checksums, so the substance sits in the linked changelog rather than the feed itself.

◆ 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.
SimpleSAMLphp
5.0DEVOPS
SimpleSAMLphp advances two maintenance branches in lockstep, security patches first.
◆ Current state
SimpleSAMLphp is maintaining the 2.4 and 2.5 lines in parallel and patching both from the same fixes. Six releases since late May split into two security releases — the 2.4.6/2.5.1 pair on 29 May and 2.5.3 on 10 August — and four bugfix releases. Release bodies carry only download links and SHA256 checksums, so the substance sits in the linked changelog rather than the feed itself.
◆ Where it's heading
The dual-branch discipline is the story: every advisory lands twice, once per supported line, which is what a SAML library embedded in long-lived identity deployments has to do for operators who cannot jump minor versions on demand. The May advisories touched HTTP-Artifact resolution and SP-Proxy setups bridging IdPs of differing trust levels — federation's sharp edges rather than everyday login flows. No feature work is visible in this window; 2.5.0 in March was the last minor.
◆ Prediction
Expect both branches to keep advancing together, with 2.4 receiving anything 2.5 gets on the security side. The feed offers no signal on when a 2.6 line might open.
