+## 0.1.2 (August 22nd, 2019)
+
+Features:
+
+* Added `extraSecretEnvironmentVars` to allow users to mount secrets as
+  environment variables
+* Added `tlsDisable` configurable to change HTTP protocols from HTTP/HTTPS 
+  depending on the value
+* Added `serviceNodePort` to configure a NodePort value when setting `serviceType` 
+  to "NodePort"
+
+Improvements:
+
+* Changed UI port to 8200 for better HTTP protocol support
+* Added `path` to `extraVolumes` to define where the volume should be 
+  mounted.  Defaults to `/vault/userconfig`
+* Upgraded Vault to 1.2.2
+
+Bugs:
+
+* Fixed bug where upgrade would fail because immutable labels were being 
+  changed (Helm Version label)
+* Fixed bug where UI service used wrong selector after updating helm labels
+* Added `VAULT_API_ADDR` env to Vault pod to fixed bug where Vault thinks
+  Consul is the active node
+* Removed `step-down` preStop since it requires authentication.  Shutdown signal
+  sent by Kube acts similar to `step-down`
