fish shell vs Slurm

fish shell vs Slurm: at a glance
What is fish shell?
fish 4.9 ships three bug-fix releases in one week to fix keyboard input regressions on macOS and non-Latin layouts
fish shell released 4.9.0 through 4.9.3 within a week, with the latter three releases fixing keyboard input regressions introduced in 4.9.0 — non-default keyboard layout bindings, IME space insertion, macOS option-key sequences, and dead-key handling. The 4.9.0 release itself added independent shift-space bindings, abbreviation descriptions in the completion pager, and Konsole compatibility workarounds. The 4.8.x cycle that preceded it brought Fluent-based localization for Rust messages, abbreviations completing in argument position, and POSIX `cd -L/-P` compliance.
What is Slurm?
Slurm 26.11 RC turns on the threadpool by default and splits containers into runtime plugins
Slurm maintains three branches (25.05, 25.11, 26.05) and shipped coordinated fixes for seven CVEs across all three on September 2; 26.05.5 in October was routine maintenance. On November 6 the first release candidate for 26.11 arrived. It enables the slurmctld threadpool by default, makes all RPC replies asynchronous, moves OCI container execution out of slurmstepd into a new runtime/oci plugin with --container-type renamed to --runtime, and hardens slurmrestd with dropped Linux capabilities and unauthenticated health endpoints.

fish 4.9 ships three bug-fix releases in one week to fix keyboard input regressions on macOS and non-Latin layouts
◆ Current state
fish shell released 4.9.0 through 4.9.3 within a week, with the latter three releases fixing keyboard input regressions introduced in 4.9.0 — non-default keyboard layout bindings, IME space insertion, macOS option-key sequences, and dead-key handling. The 4.9.0 release itself added independent shift-space bindings, abbreviation descriptions in the completion pager, and Konsole compatibility workarounds. The 4.8.x cycle that preceded it brought Fluent-based localization for Rust messages, abbreviations completing in argument position, and POSIX `cd -L/-P` compliance.
◆ Where it's heading
fish is managing a high-frequency patch cadence that reflects aggressive regression hunting — regressions are identified and fixed within days of a minor release. The Fluent localization switch and ongoing Vi mode maturation (counts for movement commands, improved word motions) indicate two parallel investment areas: multilingual accessibility and Vim-user experience. Terminal compatibility work (kitty keyboard protocol, Konsole, IME) is the current active problem domain.
◆ Prediction
The 4.9 patch cycle will close after one or two more fixes, then the team will stage a 4.10 release with the next round of scripting and interactive improvements. Keyboard protocol work (kitty, IME) will continue as the long tail of terminal compatibility issues is addressed.
Slurm

Slurm 26.11 RC turns on the threadpool by default and splits containers into runtime plugins
◆ Current state
Slurm maintains three branches (25.05, 25.11, 26.05) and shipped coordinated fixes for seven CVEs across all three on September 2; 26.05.5 in October was routine maintenance. On November 6 the first release candidate for 26.11 arrived. It enables the slurmctld threadpool by default, makes all RPC replies asynchronous, moves OCI container execution out of slurmstepd into a new runtime/oci plugin with --container-type renamed to --runtime, and hardens slurmrestd with dropped Linux capabilities and unauthenticated health endpoints.
◆ Where it's heading
26.11 is an architectural release more than a feature one: the controller's concurrency model changes by default, container support becomes a pluggable runtime layer, and slurmrestd is being prepared to run as a service behind health checks. Several options are renamed or deprecated (conmgr_threads, SLURMRESTD_JSON, become_user), so upgrades will need config review.
◆ Prediction
Expect further 26.11 release candidates fixing threadpool and async-reply regressions before a 26.11.0 GA, alongside a 26.05.6 point release on the current branch.
