 * **toast:** A new `tapToDismiss?: boolean` property has been added to the toast object.  This allows for 
 each individual toast to override the global `tapToDismiss` config.
 Closes [#178](https://github.com/Stabzs/Angular2-Toaster/issues/178).
+* **toast:** A progress bar has been added on a toast-by-toast basis with two progress directions:
+decreasing and increasing.  By default, the progress bar is disabled.
 * **toaster.css:** Styles have been rebuilt around flexbox and have removed IE and webkit-specific prefixes. 
 This allows for more compact css and should make it easier for users to override styles.  It also fixes close 
 button layout issues in Firefox, resolving [#192](https://github.com/Stabzs/Angular2-Toaster/issues/192).

+### Progress Bar
+A progress bar can be enabled per toast via the `progressBar` property.  If set to true, a progress bar will be 
+displayed that indicates how much time is remaining for the toast before it is automatically dismissed.
+
+The progress bar has two directions: `decreasing` or right-to-left and `increasing`, or left-to-right.  While defaulted 
+to `decreasing`, it can be overridden per toast:
+
+```typescript
+var toast: Toast = {
+  type: 'success',
+  progressBar: true,
+  progressBarDirection: 'increasing'  
+};
+
+this.toasterService.pop(toast);
+```
+
+
 ### On Show Callback
 An onShow callback function can be attached to each toast instance.  The callback will be invoked upon toast add.
