OSQP vs SimpleSAMLphp
A side-by-side editorial comparison of OSQP and SimpleSAMLphp — release velocity, themes, recent moves, and the top alternatives to consider.
OSQP vs SimpleSAMLphp: at a glance
What is OSQP?
QP solver that rebuilt its linear algebra layer for GPUs, then went quiet in beta.
OSQP is an operator-splitting quadratic program solver used widely as an embedded optimization backend. Its visible release history stops at the v1.0 beta from May 2023, which was a substantial rework: a pluggable linear algebra backend chosen at compile time, the separate cuOSQP GPU project folded into the main tree, and an Intel MKL backend added. That beta has not been followed by a stable v1.0 in this feed.
What is SimpleSAMLphp?
Two maintenance branches, patched in lockstep, with release notes that say nothing but a checksum.
SimpleSAMLphp is running parallel 2.4 and 2.5 maintenance branches and patching both on the same day whenever a fix lands. The August releases are a coordinated security drop across the 2.5 line plus a 2.4 bugfix a day earlier. Release bodies carry no changelog text at all — just a download link, upgrade-notes pointer, and SHA256 checksums, so the feed tells operators when to patch but never what changed.

QP solver that rebuilt its linear algebra layer for GPUs, then went quiet in beta.
◆ Current state
OSQP is an operator-splitting quadratic program solver used widely as an embedded optimization backend. Its visible release history stops at the v1.0 beta from May 2023, which was a substantial rework: a pluggable linear algebra backend chosen at compile time, the separate cuOSQP GPU project folded into the main tree, and an Intel MKL backend added. That beta has not been followed by a stable v1.0 in this feed.
◆ Where it's heading
The direction the beta set is clear — OSQP was becoming a solver core that could be retargeted at different compute hardware without changing the algorithm, with CUDA and MKL as the first two targets. Code generation and adjoint derivative computation moving into the C API point the same way, toward embedding OSQP inside other systems including differentiable pipelines.
◆ Prediction
The stable v1.0 is the obvious next milestone, but nothing in these entries indicates when or whether it landed — treat the backend rework as available only in beta form.
SimpleSAMLphp
5.0DEVOPS
Two maintenance branches, patched in lockstep, with release notes that say nothing but a checksum.
◆ Current state
SimpleSAMLphp is running parallel 2.4 and 2.5 maintenance branches and patching both on the same day whenever a fix lands. The August releases are a coordinated security drop across the 2.5 line plus a 2.4 bugfix a day earlier. Release bodies carry no changelog text at all — just a download link, upgrade-notes pointer, and SHA256 checksums, so the feed tells operators when to patch but never what changed.
◆ Where it's heading
This is pure maintenance cadence, not product development. The pattern across the last ten releases is consistent: security issues get simultaneous twin tags on both supported branches, everything else lands as branch-local bugfix points. The only release in the window that documented its own content was v2.4.6/v2.5.1 in May, which listed three GHSA advisories.
◆ Prediction
Expect the next tags to continue the twin-branch pattern — a paired 2.4.x and 2.5.x whenever an advisory lands, with content again deferred to the external changelog.
