This release adds version-scoped controls to two settings: [onlyBuiltDependencies] and [minimumReleaseAgeExclude].

Minor Changes​

Added network performance monitoring to pnpm by implementing warnings for slow network requests, including both metadata fetches and tarball downloads.

Added configuration options for warning thresholds: fetchWarnTimeoutMs and fetchMinSpeedKiBps. Warning messages are displayed when requests exceed time thresholds or fall below speed minimums

Related PR: #10025.

Patch Changes​

• Retry filesystem operations on EAGAIN errors #9959.
• Outdated command respects minimumReleaseAge configuration #10030.
• Correctly apply the cleanupUnusedCatalogs configuration when removing dependent packages.
• Don't fail with a meaningless error when scriptShell is set to false #8748.
• pnpm dlx should not fail when minimumReleaseAge is set #10037.

Minor Changes​

The minimumReleaseAgeExclude setting now supports patterns.

Minor Changes​

New setting for delayed dependency updates​

There have been several incidents recently where popular packages were successfully attacked. To reduce the risk of installing a compromised version, we are introducing a new setting that delays the installation of newly released dependencies. In most cases, such attacks are discovered quickly and the malicious versions are removed from the registry within an hour.

Minor Changes​

New setting for catalogs​

Added the cleanupUnusedCatalogs configuration. When set to true, pnpm will remove unused catalog entries during installation #9793.

Added support for JavaScript runtime installation​

Declare Node.js, Deno, or Bun in devEngines.runtime (inside package.json) and let pnpm download and pin it automatically.

It is the end of the year. A really hard year. As you may know, I live in Ukraine, so due to Russia's war against us, it was harder to lead this project than in previous years. Nevertheless, it was a good year for pnpm. We've got a lot of new users, contributors, and we have implemented many great features.

It is the end of the year and it was a good year for pnpm, so let's see how it went.

There are many ways to create a node_modules directory. Your goal must be to create the most strict one but if that is not possible, there are options to make a loose node_modules as well.

New users of pnpm frequently ask me about the weird structure of node_modules that pnpm creates. Why is it not flat? Where are all the sub-dependencies?
