What is Slurm?

Slurm patches crashes and heterogeneous-job hangs on two branches while 26.11 is in RC.

Slurm runs three branches. On November 10, 26.05.6 and 25.11.9 shipped fixes for a slurmstepd crash with stepmgr in array tasks, PMIx hangs in heterogeneous job steps, a slurmd memory leak and a heap corruption on failed RPC forwarding. The first 26.11 release candidate, out on November 6, turns on the slurmctld threadpool by default and moves OCI containers into a runtime plugin.

What is Apache OpenNLP?

Apache OpenNLP ships 3.0.0 final, closing a milestone track that ran since spring.

Apache OpenNLP runs three release lines: 1.9.x for Lucene and Solr 8 users, 2.5.x as the stable line, and the 3.0 track that went through six milestones. On 12 November the project tagged 3.0.0 final alongside a 2.5.13 patch, again shipping both lines on the same day. The tags carry no release notes in the feed, so what changed since 3.0.0-M6 is not visible here.

Slurm vs Apache OpenNLP: editorial side-by-side

S
Slurm
DEVOPS
5.0

Slurm patches crashes and heterogeneous-job hangs on two branches while 26.11 is in RC.

◆ Current state

Slurm runs three branches. On November 10, 26.05.6 and 25.11.9 shipped fixes for a slurmstepd crash with stepmgr in array tasks, PMIx hangs in heterogeneous job steps, a slurmd memory leak and a heap corruption on failed RPC forwarding. The first 26.11 release candidate, out on November 6, turns on the slurmctld threadpool by default and moves OCI containers into a runtime plugin.

◆ Where it's heading

Maintenance branches get regular crash and correctness fixes while 26.11 heads to release with new defaults. The 26.11 RC's container and threadpool changes are where behaviour will shift for sites; heterogeneous jobs and stepmgr remain areas with frequent fixes.

◆ Prediction

A second 26.11 release candidate or 26.11.0 is the next likely release, followed by more point releases on 26.05 and 25.11.

A5.0

Apache OpenNLP ships 3.0.0 final, closing a milestone track that ran since spring.

◆ Current state

Apache OpenNLP runs three release lines: 1.9.x for Lucene and Solr 8 users, 2.5.x as the stable line, and the 3.0 track that went through six milestones. On 12 November the project tagged 3.0.0 final alongside a 2.5.13 patch, again shipping both lines on the same day. The tags carry no release notes in the feed, so what changed since 3.0.0-M6 is not visible here.

◆ Where it's heading

The 3.0 milestones combined security hardening (deserialization and XXE fixes, model-loading allowlists) with new text tooling such as the Unicode normalization engine and a SymSpell spell checker, while 2.5.x added RoBERTa inference through ONNX Runtime. With 3.0.0 out, the 2.5 line is likely to move to backports only, and new work should land on 3.x.

◆ Prediction

Expect a 3.0.1 patch and continued 2.5.x security backports; whether 1.9.x gets further releases is unclear from these entries.
