IMPORTANT: This package has moved under the "@rushstack" NPM scope.

OLD NAME: @microsoft/node-core-library (3.19.3)
NEW NAME: @rushstack/node-core-library (3.19.4)

The new package's CHANGELOG.md preserves version history from before the rename.
The new package starts with a SemVer PATCH increment, since no code has changed.
