Dependency Cooldowns
A dependency cooldown is an intentional delay between when a package version is published and when your project is allowed to install it. The idea: let the wider ecosystem absorb the first hours of risk so compromised releases can be detected and yanked before they reach your build.
The practice crystallized after William Woodruff's November 2025 post showed that 8 of 10 recent supply-chain attacks had exploitation windows under a week. npm shipped `min-release-age` in v11.10.0; pnpm added `minimumReleaseAge`; Yarn added `npmMinimalAgeGate`; GitHub Dependabot rolled out native cooldown support in July 2025.
After the September 2025 axios/chalk/debug npm compromises, Datadog Security Labs recommended a 12-hour minimum cooldown, arguing even that window would have blocked the Axios worm. Packages like cooldowns.dev now ship a single script that configures min-age across pip, uv, npm, pnpm, Yarn, Bun, Deno, and Cargo at once.
Like letting food cool on the counter before eating — not to change what's inside, but to catch what shouldn't have been in there to begin with.

Why is it emerging now?
William Woodruff's November 2025 advocacy piece hit 489 points on HN; by April 2026 npm (v11.10.0), pnpm, Yarn, and Dependabot all ship native cooldown settings. Cal Paterson's April 15 rebuttal hit 186 points on HN the same week, splitting the community into pro-cooldown and pro-upload-queue camps.
Outlook
6-month signal projection and commercial timeline.
Native support in every major package manager plus high-profile npm worms makes cooldowns the default posture for security-conscious teams within a year.
Risk · Cal Paterson's free-rider critique plus pressure on maintainers to ship fixes faster could push the category toward server-side upload queues instead.

Cal Paterson is right that cooldowns exploit the less-cautious. He's also wrong that you should wait for PyPI to fix it. Here's why your team should ship cooldowns Monday and argue ethics later.
