CHANGELOG.md

@@ -21,6 +21,7 @@ Yarn now accepts sponsorships! Please give a look at our [OpenCollective](https:
 - `yarn workspaces foreach` now automatically enables the `-v,--verbose` flag in interactive terminal environments.
 - `yarn npm audit` no longer takes into account publish registries. Use [`npmAuditRegistry`](https://yarnpkg.com/configuration/yarnrc#npmAuditRegistry) instead.
 - The `--assume-fresh-project` flag of `yarn init` has been removed. Should only affect people initializing Yarn 4+ projects using a Yarn 2 binary.
+- `yarn init` no longer enables zero-installs by default.
 - Yarn will no longer remove the old Yarn 2.x `.pnp.js` file when migrating.
 - The `pnpDataPath` option has been removed to adhere to our new [PnP specification](https://yarnpkg.com/advanced/pnp-spec). For consistency, all PnP files will now be hardcoded to a single value so that third-party tools can implement the PnP specification without relying on the Yarn configuration.
