##### Patch Changes

-
[#&#8203;1509](https://redirect.github.com/lint-staged/lint-staged/pull/1509)
[`8827ebf`](https://redirect.github.com/lint-staged/lint-staged/commit/8827ebf29dc8f25149a36450b4a0023425202e18)
Thanks [@&#8203;iiroj](https://redirect.github.com/iiroj)! - Change
*lint-staged*'s dependencies to use [caret (`^`)
ranges](https://docs.npmjs.com/cli/v6/using-npm/semver#caret-ranges-123-025-004)
instead of [tilde
(`~`)](https://docs.npmjs.com/cli/v6/using-npm/semver#tilde-ranges-123-12-1).
This makes it easier for package managers to perform dependency
management when minor-level updates are also permitted instead of just
patch-level.
