 # Drupal VM Changelog
 
+## 4.7.0 "Water, Music, and Tronaction" (2017-10-06)
+
+### Breaking Changes
+
+  * In Issue #1520, the precedence of configuration override files was changed slightly. Previously, `[environment].config.yml` overrode all other configuration files, including `local.config.yml`. The intention of the local config file is that it is always the final override. The order of config file precedence (from lowest to highest) is now:
+    1. `config.yml`
+    2. `secrets.yml`
+    3. `[environment].config.yml`
+    4. `local.config.yml`
+
+### New/changed variables in default.config.yml
+
+  * Removed `geerlingguy/ubuntu1204` support (LTS support ended in April).
+  * Default `vagrant_hostname` is now `drupalvm.test` (Google owns `.dev` and some DNS issues have forced us to switch to `.test` as the default).
+  * Added `drupal_db_host: localhost` to fix a DB connection issue with Debian 9 'Stretch'.
+  * Added `headers.load` to `apache_mods_enabled`.
+  * Updated `drush_version` to `8.1.14`.
+  * Updated example `post_provision_scripts` path to include the full `playbook_dir`-based path.
+

+  * #1551: Add PHP 7.2 support via php-versions role.
