This version fixes a problem where Yarn wasn't forwarding SIGTERM to the binary spawned via yarnPath. It also makes yarn init -2 compatible with Corepack. The behaviour of yarn init (without -2) doesn't change.
Remember that Yarn 1.x won't receive further functional improvements. We recommend you to switch to the recently-released 3.0, and to ping us on Discord if you find issues when migrating (also check our Migration Guide).
