 # Drupal VM Changelog
 
+## 4.5.0 "Break In (For Strings, Flutes, and Celesta)" (2017-05-24)
+
+### Breaking Changes
+
+  * The default `nodejs_version` is now set to `6.x`; if you need to stay on `0.12` or some other version, be sure to set the version explicitly in your own `config.yml`.
+
+### New/changed variables in default.config.yml
+
+  * Changed variables:
+    * `nodejs_version: "6.x"` (was `0.12`)
+  * New variables:
+    * Reconfigurable templates for Drush Aliases:
+      * `drush_aliases_host_template: "templates/drupalvm.aliases.drushrc.php.j2"`
+      * `drush_aliases_guest_template: "templates/drupalvm-local.aliases.drushrc.php.j2"`
+    * Reconfigurable template for Nginx hosts:
+      * `nginx_vhost_template: "templates/nginx-vhost.conf.j2"`
+    * `firewall_enabled: true` (allows the disabling of Drupal VM's default firewall, e.g. for Docker usage)
+    * `php_xdebug_remote_host: "{{ ansible_default_ipv4.gateway }}"` (prevents warnings when using Xdebug)
+    * New Docker configuration options:
+      * `docker_container_name: drupal-vm`
+      * `docker_image_name: drupal-vm`
+      * `docker_image_path: ~/Downloads`
+    * New hostname configuration options:
+      * `hostname_configure: true`
+      * `hostname_fqdn: "{{ vagrant_hostname }}"`
