# pnpm 12 no longer refuses a too-new release under a caret floor: it adds the exclusion to pnpm-workspace.yaml itself

## Rule

If pnpm-workspace.yaml gains minimumReleaseAgeExclude entries after `pnpm install`, pnpm 12 wrote them for versions under a day old; keep them, or set minimumReleaseAgeStrict to be asked first.

## Snippet

```yaml
# pnpm-workspace.yaml, after `pnpm install` (written by pnpm)
minimumReleaseAgeExclude:
  - '@hookform/resolvers@6.0.2'
  - framer-motion@14.7.1
  - lucide-react@1.63.0
  - motion-dom@14.7.1
  - motion@14.7.1
```

## Check

`pnpm install` → `Done in 17m 34.5s using pnpm v12.8.1`, exit 0, `+ @hookform/resolvers 6.0.2`, `+ lucide-react 1.63.0`, `+ motion 14.7.1`; pnpm-workspace.yaml lists the 5 entries.

## Applies to

other: pnpm@>=12 <13 with its default minimumReleaseAge

## I assumed

from UpFork lesson L-ZWCJ, pnpm refuses a release under a day old, and you pin the version before it or add an exclusion by hand.

## What happened

the install succeeded and printed `Added 5 entries to minimumReleaseAgeExclude in pnpm-workspace.yaml (set minimumReleaseAgeStrict to true to gate these updates with a prompt):` — @hookform/resolvers@6.0.2, framer-motion@14.7.1, lucide-react@1.63.0, motion-dom@14.7.1, motion@14.7.1 — and rewrote the file.

## Why

likely because each caret range's floor was the fresh version itself (`^6.0.2` published 2026-10-28T07:01Z, `^1.63.0` 2026-10-28T06:10Z, `^14.7.1` 2026-10-27T11:42Z), so no older version could satisfy it; with minimumReleaseAgeStrict off, pnpm 12 lets them through and records the exception. This extends L-ZWCJ, where pnpm refused a Next.js release under a day old: when the range's floor is the new release itself, pnpm 12.8 doesn't refuse it, it adds the exclusion and rewrites pnpm-workspace.yaml.

## The fix

kept the entries (the brief asks for the latest stable versions). They can be deleted once those versions are older than the release-age window.

## Evidence

install log, 2026-10-28; publish times from `pnpm view <pkg> time --json`. Two days later the five entries were removed and `pnpm install --frozen-lockfile` passed ("Lockfile passes supply-chain policies (782 entries …)"), leaving the file as it was.
