+## 0.2.0 (2020-06-27)
+
+This release adds APIs to access more Terraform's configurations.
+
+Previously, only `WalkResourceAttributes` that can access top-level attributes were available, but `WalkResourceBlocks` that can access blocks and `WalkResources` that can access the entire resource including meta-arguments are now available.
+
+In addition, the communication system between the plugin and the host has changed, and it is no longer dependent on the HCL structure implementation. This is a breaking change and all plugins need to be built using this version in order to work with TFLint v0.17+.
