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 reaches RC after a beta line that reworked config, mocking defaults, and the browser runner.

Vitest has spent the last two and a half months in a v5.0.0 beta train, and 5.0.0-rc.1 is the first release candidate. Each beta carried its own block of breaking changes rather than deferring them: config lookup no longer walks ancestor directories, @vitest/runner was inlined and unpublished, webdriverio was dropped, mocks now clear before each test by default, and reporter output moved to a .vitest directory. The RC adds nested projects, a shared Vite server across inline projects, and a failure when an asynchronous assertion is never awaited.

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 reaches RC after a beta line that reworked config, mocking defaults, and the browser runner.

◆ Current state

Vitest has spent the last two and a half months in a v5.0.0 beta train, and 5.0.0-rc.1 is the first release candidate. Each beta carried its own block of breaking changes rather than deferring them: config lookup no longer walks ancestor directories, @vitest/runner was inlined and unpublished, webdriverio was dropped, mocks now clear before each test by default, and reporter output moved to a .vitest directory. The RC adds nested projects, a shared Vite server across inline projects, and a failure when an asynchronous assertion is never awaited.

◆ Where it's heading

The through-line across beta.4 to rc.1 is consolidation of the runner's architecture — one config resolution path, one Vite server, one project tree that can nest — paired with defaults that surface mistakes instead of tolerating them (strict toHaveTextContent, hoistable-scope errors, unawaited assertions failing). The browser mode is being narrowed to a single first-party stack rather than a plugin matrix. Performance work is now targeted at memory retention in vm pools and large --changed graphs, which reads as pre-GA cleanup rather than new capability.

◆ Prediction

With breaking changes still landing in rc.1, expect at least one more RC to settle the nested-projects and shared-server behaviour before a v5.0.0 final.
