Update Drupal 8 Core with dev modules
The package webflo/drupal-core-require-dev provides the require-dev dependencies of drupal/core as a standalone package and is used by many developers.
This dependency prevented updating Drupal 8 Core via Drop Guard.
Some requests arrived us to respect that package and now Drop Guard supports the update Drupal 8 Core together with webflo/drupal-core-require-dev.
Now if the webflo/drupal-core-require-dev package is using in your project, Drop Guard will execute update for drupal/core and webflo/drupal-core-require-dev up to the equal versions.
Also we would like to remind that every project using "provide only minor updates for Drupal Core" will be updated anyway whatever value "Composer update mode". Because in this case, Drop Guard will use "ignore versions constraint" mode and therefore "composer require" command.
It will make the update process easier for our users! If you have any questions just reach out to us.
