I just released Drupal VM 6.0.0 today, and it is the best version of Drupal VM yet!
The main goals for this new version are stability and compatibility.
Originally I was going to drop some features that are helpful for people running older Drupal 7 sites, but since Drupal 7's End of Life was just extended into 2022, I decided to extend the support for some features like Drush make files, as many users of Drupal VM still maintain Drupal 7 sites, or use Drupal VM to test the upgrade from Drupal 7 to Drupal 8 or 9.
The default PHP version was upgraded from PHP 7.2 to 7.4 in Drupal VM 6, and this new version should work great with almost any Drupal 7, 8, or 9 website (in fact, PHP 7.3 is Drupal 9's minimum requirement!).
The final major feature is defaulting everything to Drupal 9. Drupal VM gives you easy tools to build a new Drupal 9 website no matter what OS you use, and now when you build a new website, you get Drupal 9 by default!
If you're already using Drupal VM, go check out the release notes to make sure you update your configuration for the new version, then upgrade to 6.0.0. If you don't use it, now's a great time to try it out!
