Quoting the pnpm documentation: “Catalogs are a workspace feature for defining dependency version ranges as reusable constants. Constants defined in catalogs can later be referenced in package.json files.”

Socket has also published a blog post about pnpm 9.5.

Highlights (quoting their Mastodon post):

• Better Browser Mode support (still experimental)
• Stability improvements (forks pool is now the default)
• New blob reporter to merge reports from different processes
• A lot of bug fixes

• ESLint v9.7.0 supports ECMAScript 2025 duplicate capturing groups in regular expressions in its core rules.
• The no-restricted-imports rule has a new option regex to specify modules using a regular expression pattern.
