* chore(release): 11.28.0, pacquet 12.7.0, pnpr 0.1.0-alpha.13 * docs(release): curate the 11.28.0 and 12.7.0 release pages Group both pages under subject headings with a lead paragraph that names the headline changes and the security fixes, and move the security entries to the top of the patch section. Merge entries that describe one change: the node shim version files, ranged selectors without a package.json, SemVer build metadata, completion injection, custom modulesDir command lookup, list --only-projects, store status, npm_execpath, catalog and npm-alias workspace edges, the macOS CA fallback, and the prepare/devPreinstall skips. Drop entries that describe no change a published version could show: the test-only --no-optional entry on both pages, the exported CreateNewStoreControllerOptions type, the publish availability-probe fix for a flag first shipping in 12.7.0, and the executable-bit check the Rust CLI never had wrong.

Fast, disk space efficient package manager:
- Fast. Up to 2x faster than the alternatives (see benchmark).
- Efficient. Files inside
node_modulesare linked from a single content-addressable storage. - Great for monorepos.
- Strict. A package can access only dependencies that are specified in its
package.json. - Deterministic. Has a lockfile called
pnpm-lock.yaml. - Works as a Node.js version manager. See pnpm runtime.
- Works everywhere. Supports Windows, Linux, and macOS.
- Battle-tested. Used in production by teams of all sizes since 2016.
- Experimental Rust port. Includes pacquet, an experimental port of the CLI written in Rust.
- See the full feature comparison with npm and Yarn.
To quote the Rush team:
Microsoft uses pnpm in Rush repos with hundreds of projects and hundreds of PRs per day, and we’ve found it to be very fast and reliable.

Background
pnpm uses a content-addressable filesystem to store all files from all module directories on a disk. When using npm, if you have 100 projects using lodash, you will have 100 copies of lodash on disk. With pnpm, lodash will be stored in a content-addressable storage, so:
- If you depend on different versions of lodash, only the files that differ are added to the store.
If lodash has 100 files, and a new version has a change only in one of those files,
pnpm updatewill only add 1 new file to the storage. - All the files are saved in a single place on the disk. When packages are installed, their files are linked from that single place consuming no additional disk space. Linking is performed using either hard-links or reflinks (copy-on-write).
As a result, you save gigabytes of space on your disk and you have a lot faster installations!
