+## Breaking change
+
+Starting from August 2019, GitHub switch [Actions syntax from HCL to YAML](https://help.github.com/en/articles/migrating-github-actions-from-hcl-syntax-to-yaml-syntax).  
+The previous syntax will no longer be supported by GitHub on September 30, 2019.
+
+As a consequence, __please use v2.0.0+__ release and note that __all v1.x.x are deprecated__ and will no longer work on September 30, 2019.
