## publint 0.3

### Breaking changes

- Checks repository.url when repository.type is omitted, so object-form repository values are checked for deprecated protocols, invalid Git URLs, and shorthand URLs. (0.3.24) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.24)

### New APIs and options

- The USE_FILES message now reports which internal files or directories triggered it through args.internalFilePaths. (0.3.23) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.23)

### Behavior and default changes

- The USE_FILES suggestion now recursively detects test files such as *.test.js and *.spec.ts. (0.3.23) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.23)
- Repository validation accepts a broader range of git URLs. (0.3.22) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.22)
- The USE_FILES suggestion recognizes more common internal files. (0.3.22) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.22)
- Publint skips file existence checks when crawling subpath imports because they may be dev-only and unused after bundling or publishing. (0.3.15) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.15)

### Tooling

- Publint now supports npm v12. (0.3.22) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.22)
- Publint now supports pnpm v11. (0.3.22) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.22)
- Suggests adding "sideEffects": false when bundler-oriented package fields or conditions are detected and the field is missing. (0.3.21) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.21)
- Lint messages use less forceful wording about breaking changes. (0.3.20) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.20)
- Warns when published nested package.json files define exports or imports, which Node.js ignores outside the package root. (0.3.19) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.19)

### Fixes and other changes

- Skips file existence checks for `browser` field values that point at another package. (0.3.25) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.25)

- Suggest adding engines.node when it is missing from detected Node.js packages. (0.3.20) — [release notes](https://github.com/publint/publint/releases/tag/publint%400.3.20)
