 changes
 ================================================================================
 
+**1.2.4** - 2021/04/03
+
+- upgrade most dependencies, but not CoffeeScript, since the latest
+  version generates code that can't be run in older versions of node - [pr #50][]
+
+- change to call `yaml.load()` instead of `yaml.safeLoad()` since it's no
+  longer supported, noticed via an error message: - [pr #50][]
+
+  ```
+  Error: Function yaml.safeLoad is removed in js-yaml 4. Use yaml.load instead, which is now safe by default.
+  ```
