SimpleSAMLphp vs Rust
A side-by-side editorial comparison of SimpleSAMLphp and Rust — release velocity, themes, recent moves, and the top alternatives to consider.
SimpleSAMLphp vs Rust: at a glance
What is SimpleSAMLphp?
Two maintained branches, and most of the shipping cadence is CVE response.
SimpleSAMLphp is running 2.4.x and 2.5.x in parallel, patching both from the same fix sets. Of the eight most recent releases, four are security releases and the rest are unlabelled bugfix drops. Release notes carry no feature detail at all — each is a short boilerplate paragraph plus SHA-256 checksums for the slim and full tarballs, with the actual content deferred to a separate changelog and upgrade notes.
What is Rust?
Rust's six-week train is spending its budget on soundness, not surface area.
Rust is on its unchanged six-week cadence, with 1.97 current and two point releases (1.96.1, 1.97.1) pushed out for CVEs and codegen miscompilations. The change budget lands in three places: const-context and integer/pointer API stabilizations, Cargo configuration graduating to stable (build.warnings, resolver.lockfile-path), and a steady stream of compatibility tightening around Pin, coercions and enum layout. 1.97.0 also flipped the default symbol mangling scheme to v0.

Two maintained branches, and most of the shipping cadence is CVE response.
◆ Current state
SimpleSAMLphp is running 2.4.x and 2.5.x in parallel, patching both from the same fix sets. Of the eight most recent releases, four are security releases and the rest are unlabelled bugfix drops. Release notes carry no feature detail at all — each is a short boilerplate paragraph plus SHA-256 checksums for the slim and full tarballs, with the actual content deferred to a separate changelog and upgrade notes.
◆ Where it's heading
This is maintenance-mode infrastructure, and the release rhythm is set by vulnerability disclosure rather than a roadmap. The dual-branch discipline — shipping 2.4.6 and 2.5.1 within a minute of each other for the same three advisories — indicates a deployed base that cannot all move to the newer minor. The vulnerability classes are notable in themselves: HTTP-Artifact resolution and SP-Proxy deployments bridging identity providers of different trust levels.
◆ Prediction
Expect the 2.4 and 2.5 branches to keep receiving paired patches, with 2.4 continuing until an announced end-of-life. The entries give no indication of what is planned beyond the 2.5 line.

2.5DEVOPS
Rust's six-week train is spending its budget on soundness, not surface area.
◆ Current state
Rust is on its unchanged six-week cadence, with 1.97 current and two point releases (1.96.1, 1.97.1) pushed out for CVEs and codegen miscompilations. The change budget lands in three places: const-context and integer/pointer API stabilizations, Cargo configuration graduating to stable (build.warnings, resolver.lockfile-path), and a steady stream of compatibility tightening around Pin, coercions and enum layout. 1.97.0 also flipped the default symbol mangling scheme to v0.
◆ Where it's heading
Across these six releases the Compatibility Notes section is consistently longer than the Language section, which is the clearest signal of where the project is: closing soundness holes rather than adding syntax. Pin deref coercions, unsize coercions into Pin, const generic argument checking and repr(Int) layout edge cases were all corrections of things the compiler previously allowed by accident. Platform work is moving existing targets up-tier (seven Apple aarch64 targets to Tier 2, RISC-V profile features) instead of adding new tier-3 targets, and Cargo keeps absorbing workflow that used to live in CI shell scripts.
◆ Prediction
Expect the next release to hold the shape: a small batch of newly const-stable APIs, one or two more Cargo config stabilizations, and further coercion and layout corrections shipped with future-compatibility warnings. If v0 mangling breaks debugger or profiler tooling in the field, that surfaces as a point release rather than a revert.
