Release Notes

lerna/lerna

v4.0.0

Compare Source

Features

• Consume named exports of sibling modules (63499e3)
• deps: import-local@^3.0.2 (e0e74d4)
• Drop support for Node v6.x & v8.x (ff4bb4d)

BREAKING CHANGES

• Node v6.x & v8.x are no longer supported. Please upgrade to the latest LTS release.

Here's the gnarly one-liner I used to make these changes:

npx lerna exec --concurrency 1 --stream -- 'json -I -f package.json -e '"'"'this.engines=this.engines||{};this.engines.node=">= 10.18.0"'"'"

(requires npm i -g json beforehand)

3.22.1 (2020-06-09)

Note: Version bump only for package lerna
