New location of APKs files

Hello all,
We are using scripts to deploy automatically APK on an internal store. These scripts take APK in : build/output/apk folder.
But since the new version of android plugin 3.0.0 (which uses gradle 4.1), the location of these APK changed.
New path : build/output/apk/{buildType}

Why did you integrate new path with the build type ?

But in the documentation, there is no trace about this change :
https://developer.android.com/studio/run/index.html#reference
it’s said : All built APKs are saved in project-name/module-name/build/outputs/apk/.
