I could find older Bitnami Drupal stacks and from what I read it looks like I need to request one. Would it be possible to get an Ubuntu 12.04 Drupal stack running php 5.3? Ideally something I can simply launch with vagrant.
Sorry for the delay. You can download Bitnami Drupal 7.15 with PHP 5.3 using this link:
Also, you can check the Bitnami Drupal changelog and let us know if you need another version.https://bitnami.com/stack/drupal/changelog.txt
Hope it helps! Please, let us know if you need anything else.
