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.

What is wk?

wk spent one release fixing what empty means, then went quiet.

wk provides the lightweight geometry vectors and streaming handler interface that sit underneath sf and the rest of R's geospatial stack. The 0.7 and 0.8 lines built out the surface — PROJJSON CRS lookup, ring winding, coordinate replacement functions, hex conversion — and 0.9.0 landed breaking changes to how empty and null points are represented. The three releases since are entirely reactive: compile under STRICT_R_HEADERS, fix format strings for R-devel, pass tests against a new sf.

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.

wk spent one release fixing what empty means, then went quiet.

◆ Current state

wk provides the lightweight geometry vectors and streaming handler interface that sit underneath sf and the rest of R's geospatial stack. The 0.7 and 0.8 lines built out the surface — PROJJSON CRS lookup, ring winding, coordinate replacement functions, hex conversion — and 0.9.0 landed breaking changes to how empty and null points are represented. The three releases since are entirely reactive: compile under STRICT_R_HEADERS, fix format strings for R-devel, pass tests against a new sf.

◆ Where it's heading

This looks like a foundation package that has reached the shape it wanted. Feature work stopped after 0.9.2 and what remains is upkeep triggered by R-devel, compiler flags and sf releases — maintenance defined by other people's changes, which for a dependency this low in the stack is a reasonable end state rather than neglect. The unresolved question is whether anything still drives it forward now that the empty-geometry semantics are settled.

◆ Prediction

The entries do not support a confident prediction of new features; on this evidence the next release is most likely another compatibility fix prompted by sf or R-devel.
