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 Eureka?

Eureka broke a two-and-a-half-year silence with a release candidate, not a release.

Netflix's service registry had been quiet since early 2024, when three release candidates for 1.10.19 were cut in a single day with identical commit lists and never promoted. A fourth candidate in August 2026 finally moved: allocation-reduction work backported from the 2.x line, VIP address lookup metrics, servo replaced with spectator in the client, and xstream and jettison upgraded for known CVEs. The 2.x branch's last visible activity, 2.0.2, was two dependency-level changes.

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.

2.5

Eureka broke a two-and-a-half-year silence with a release candidate, not a release.

◆ Current state

Netflix's service registry had been quiet since early 2024, when three release candidates for 1.10.19 were cut in a single day with identical commit lists and never promoted. A fourth candidate in August 2026 finally moved: allocation-reduction work backported from the 2.x line, VIP address lookup metrics, servo replaced with spectator in the client, and xstream and jettison upgraded for known CVEs. The 2.x branch's last visible activity, 2.0.2, was two dependency-level changes.

◆ Where it's heading

The shape of this release is maintenance by a project that still has production weight but no active feature agenda. The work that landed is dependency hygiene, allocation reduction and observability — what you ship to keep an existing fleet running, not what you ship to win new adoption. That 1.10.19 has sat in candidate state for over two years while the 2.x line stalled tells its own story.

◆ Prediction

The entries do not support a confident call on whether 1.10.19 is promoted to a final release; the pattern so far is candidates that expire rather than ship.
