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 Slurm?

Slurm 26.05 makes SLUID the default job identity and pulls TLS into the daemons.

Slurm is maintaining three branches concurrently — 26.05 as the new major line, 25.11 as the stable one, and 25.05 still receiving fixes — and releases them in same-minute pairs. The 26.05 line introduces SLUID as the default identifier used in cgroup paths and step lookups, and a tls/s2n path with a certgen plugin for generating step certificates. Everything else in this window is correctness work: controller crashes under load, shutdown and reconfigure races, memory leaks in slurmstepd and slurmrestd, and cross-version compatibility between mismatched daemons.

SimpleSAMLphp vs Slurm: editorial side-by-side

S0.0

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.

5.0

Slurm 26.05 makes SLUID the default job identity and pulls TLS into the daemons.

◆ Current state

Slurm is maintaining three branches concurrently — 26.05 as the new major line, 25.11 as the stable one, and 25.05 still receiving fixes — and releases them in same-minute pairs. The 26.05 line introduces SLUID as the default identifier used in cgroup paths and step lookups, and a tls/s2n path with a certgen plugin for generating step certificates. Everything else in this window is correctness work: controller crashes under load, shutdown and reconfigure races, memory leaks in slurmstepd and slurmrestd, and cross-version compatibility between mismatched daemons.

◆ Where it's heading

The bulk of the engineering effort visible here goes to concurrency and lifecycle correctness in slurmctld — races between the purge thread and job/node write locks, accounting_storage callers racing plugin teardown, connection plugin initialization ordering, forwarding threads outliving shutdown. That is the profile of a codebase being hardened for larger and busier clusters rather than one adding scheduling features. The second thread is upgrade tolerance: multiple fixes exist purely to keep a 26.05 slurmd working with a 24.11 sattach or a 25.05 slurmstepd, which tells you how staged real site upgrades are.

◆ Prediction

Expect 26.05.x to keep issuing fixes for the SLUID transition and for mixed-version daemon combinations, since both are where this window's regressions cluster. The 25.05 line looks close to the end of its fix stream, with its recent releases limited to shutdown races and build compatibility.
