What is distributed?

Dask's scheduler spent the year deleting deprecated API, not adding surface.

distributed is cutting frequent tags with little in them. The substantive release in the window is 2026.6.0, which removed deprecations across the scheduler, worker, nanny, CLI, security and deploy modules in roughly twenty separate cleanups and moved CI to pixi. 2026.7.0 follows with a breaking scatter change and a scheduler_info() default change; the two most recent tags are a backport and an empty release with no changes at all.

What is Vitest?

Vitest 5 is in bug-fix mode: the second RC is almost entirely hardening

rc.2 carries one feature — a custom title for the GitHub Actions summary — and otherwise fixes the failure modes the RC period surfaced. The browser mode gets most of it: failing instead of hanging when the browser stops responding, exiting cleanly on disconnect during cancellation, and triggering Chromium GC when disk runs low. Snapshot evaluation moved server-side to work under a no-unsafe-eval CSP, and the UI now requires auth for coverage reports and every subtree request.

distributed vs Vitest: editorial side-by-side

D5.0

Dask's scheduler spent the year deleting deprecated API, not adding surface.

◆ Current state

distributed is cutting frequent tags with little in them. The substantive release in the window is 2026.6.0, which removed deprecations across the scheduler, worker, nanny, CLI, security and deploy modules in roughly twenty separate cleanups and moved CI to pixi. 2026.7.0 follows with a breaking scatter change and a scheduler_info() default change; the two most recent tags are a backport and an empty release with no changes at all.

◆ Where it's heading

The direction is consolidation. A single maintainer is systematically retiring API that had been deprecated for years, tightening type annotations and chasing flaky tests, while the feature surface stays flat. Python 3.14 support and a PyArrow floor in 2026.1.2 fit the same pattern of keeping the runtime current rather than extending it.

◆ Prediction

With the deprecation sweep largely done and pixi now driving CI, the next releases most likely continue as small breaking cleanups on top of a stable feature set rather than introducing new scheduler capability.

5.0

Vitest 5 is in bug-fix mode: the second RC is almost entirely hardening

◆ Current state

rc.2 carries one feature — a custom title for the GitHub Actions summary — and otherwise fixes the failure modes the RC period surfaced. The browser mode gets most of it: failing instead of hanging when the browser stops responding, exiting cleanly on disconnect during cancellation, and triggering Chromium GC when disk runs low. Snapshot evaluation moved server-side to work under a no-unsafe-eval CSP, and the UI now requires auth for coverage reports and every subtree request.

◆ Where it's heading

The v5 line has spent four betas and two candidates reshaping config resolution, projects, mocking defaults, and the benchmark API; this candidate adds nothing to that surface and only stabilizes it. The concentration of browser-mode and pool fixes says that is where the remaining risk sits, and where real-world RC adoption is finding edges.

◆ Prediction

On this trajectory the next tag is either a final 5.0.0 or one more candidate, with browser mode the deciding factor rather than any remaining API work.
