+## 5.1.0 "Recognizer" (2019-12-03)

+
+### New/changed variables in default.config.yml
+
+  * `drupalvm_ansible_version_min: '2.5'` (was `'2.4'`)
+  * `php_version` supports `"7.2"`, `"7.3"`, or `"7.4"` (5.6, 7.0, and 7.1 dropped)
+
+### Improvements

+  * #1993: Add PHP 7.4 support. Drop 5.6, 7.0, and 7.1 support.
+  * Updated roles: mailhog, postgresql, php-versions.
