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.

What is MapServer?

Five of MapServer's last six releases exist to fix security advisories.

Since 8.6.0 shipped in December 2025, every release on this feed has been a security release. 8.6.1 through 8.6.4 each carried one or two advisories, covering the SLD parser, the OpenLayers WMS template and PostGIS support. 8.6.5 carried six at once, spanning OGC API Features, WCS, the OpenLayers viewer, WMS GetLegendGraphic, and both MySQL and PostgreSQL JOIN handling. Every note repeats that 7.6 security support has ended and 8.4, 8.2 and 8.0 are unsupported.

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.

2.5

Five of MapServer's last six releases exist to fix security advisories.

◆ Current state

Since 8.6.0 shipped in December 2025, every release on this feed has been a security release. 8.6.1 through 8.6.4 each carried one or two advisories, covering the SLD parser, the OpenLayers WMS template and PostGIS support. 8.6.5 carried six at once, spanning OGC API Features, WCS, the OpenLayers viewer, WMS GetLegendGraphic, and both MySQL and PostgreSQL JOIN handling. Every note repeats that 7.6 security support has ended and 8.4, 8.2 and 8.0 are unsupported.

◆ Where it's heading

The advisory pattern is the story: the vulnerabilities cluster in the request-parsing and templating paths that turn user input into output, which is the oldest and most exposed part of a CGI-era mapping server. Concentrating all support on the 8.6 branch and repeatedly saying so is the project's way of forcing an upgrade it cannot otherwise compel. Feature content is not visible in this feed at all.

◆ Prediction

The cadence suggests further 8.6.x security releases at roughly monthly intervals rather than a feature release in the near term.
