What is ellipsis?

ellipsis' checks live in rlang now; the package is a compatibility shim.

ellipsis provides check_dots_used(), check_dots_unnamed() and check_dots_empty() for catching arguments silently swallowed by dots. Its functional development finished in 2019 across the 0.2.0 and 0.3.0 releases. The two releases since deal only with rlang and CRAN, and 0.3.3 makes the rlang dependency unconditional.

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.

0.0

ellipsis' checks live in rlang now; the package is a compatibility shim.

◆ Current state

ellipsis provides check_dots_used(), check_dots_unnamed() and check_dots_empty() for catching arguments silently swallowed by dots. Its functional development finished in 2019 across the 0.2.0 and 0.3.0 releases. The two releases since deal only with rlang and CRAN, and 0.3.3 makes the rlang dependency unconditional.

◆ Where it's heading

The package built its full surface quickly, hardened it once by switching the check functions from warnings to errors, then saw the ideas move upstream. These checks are part of rlang's own API now, which leaves ellipsis as a compatibility layer for packages still importing it directly. The 0.3.3 change to depend on rlang unconditionally states that relationship plainly.

◆ Prediction

With the functionality living in rlang, the next release is most likely another CRAN-driven fix; there is no sign of new checks being added here.

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.
