SimpleSAMLphp vs libosmium
A side-by-side editorial comparison of SimpleSAMLphp and libosmium — release velocity, themes, recent moves, and the top alternatives to consider.
SimpleSAMLphp vs libosmium: at a glance
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.
What is libosmium?
libosmium is a stable OSM parsing library whose main work now is shedding old dependencies
libosmium ships roughly once or twice a year and the release notes read accordingly: a handful of additions, a longer list of fixes, and a steady drumbeat of code cleanups. Recent cycles have been dominated by removing things — Google Sparsehash, the ancient Proj projection support, regex filters, and a series of long-deprecated classes. The library's core job of reading and writing OSM data has been stable long enough that most fixes now cluster around compression edge cases and PBF parsing tolerance.

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.

libosmium is a stable OSM parsing library whose main work now is shedding old dependencies
◆ Current state
libosmium ships roughly once or twice a year and the release notes read accordingly: a handful of additions, a longer list of fixes, and a steady drumbeat of code cleanups. Recent cycles have been dominated by removing things — Google Sparsehash, the ancient Proj projection support, regex filters, and a series of long-deprecated classes. The library's core job of reading and writing OSM data has been stable long enough that most fixes now cluster around compression edge cases and PBF parsing tolerance.
◆ Where it's heading
The direction is consolidation rather than expansion. C++14 became the floor in 2.21.0, CMake 3.10 in 2.23.0, and each release trims another external dependency or workaround for an obsolete compiler. What new surface does appear is narrow and pragmatic: one spare bit in a Location, a TagList comparison, a UTF-8 validity helper — small affordances for downstream tools like osmium-tool and osm2pgsql rather than new capability. The 2.23.1 revert is a useful signal that the maintainers treat diff and extract-update correctness as the property they will not trade for tidier ordering.
◆ Prediction
Expect the deprecation-removal pattern to continue, with RapidJSON support the most likely next casualty given it was marked deprecated back in 2.19.0. Nothing in the entries suggests a change in scope; the next release will most plausibly be another small additions-plus-fixes cycle.
