Bumps tar from 6.2.1 to 7.5.21.

Changelog

Sourced from tar's changelog.

Changelog

7.5

  • Added zstd compression support.
  • Consistent TOCTOU behavior in sync t.list
  • Only read from ustar block if not specified in Pax
  • Fix sync tar.list when file size reduces while reading
  • Sanitize absolute linkpaths properly
  • Prevent writing hardlink entries to the archive ahead of their file target

7.4

  • Deprecate onentry in favor of onReadEntry for clarity.

7.3

  • Add onWriteEntry option

7.2

  • DRY the command definitions into a single makeCommand method, and update the type signatures to more appropriately infer the return type from the options and arguments provided.

7.1

  • Update minipass to v7.1.0
  • Update the type definitions of write() and end() methods on Unpack and Parser classes to be compatible with the NodeJS.WritableStream type in the latest versions of @types/node.

7.0

  • Drop support for node <18
  • Rewrite in TypeScript, provide ESM and CommonJS hybrid interface
  • Add tree-shake friendly exports, like import('tar/create') and import('tar/read-entry') to get individual functions or classes.
  • Add chmod option that defaults to false, and deprecate noChmod. That is, reverse the default option regarding explicitly setting file system modes to match tar entry settings.
  • Add processUmask option to avoid having to call process.umask() when chmod: true (or noChmod: false) is set.

PR Summary

Medium Risk
Major-version bump on the publish tarball path with tar 7 default/behavior changes, though usage is limited to tar.c() and Node ≥20 is already required.

Overview
Upgrades the tar dependency in libs/blockprotocol from 6.2.1 to 7.5.21, with matching yarn.lock entries for the v7 stack (@isaacs/fs-minipass, updated chownr / minizlib / minipass / yallist). Other packages in the monorepo can still resolve tar@6.2.1 via separate lockfile ranges.

The Block Protocol CLI only uses tar.c() when packaging a block folder for publish (publish.js); no application code changes accompany the bump. tar 7 is a major release (Node 18+, default chmod behavior change, TypeScript/ESM packaging) while this package already requires Node ≥20.

Default tar import breaks under v7

High Severity

Bumping tar to v7 switches it to a native ESM hybrid that only exposes named exports (c/create, etc.). publish.js still uses import tar from "tar", which worked via CommonJS interop on v6 but fails at runtime under Node ESM with no default export, so blockprotocol publish cannot load.
