+## v1.0.0
+
+### New
+
+ - `errorHandler.run(BlockExecutor)` saves you from a `try/catch` block or two 
+   ```java
+     try {
+        doSomething();
+     } catch(Exception ex) {
+        errorHandler.handle(ex);
+     }
+     
+     // can now be written as
+     
+     errorHandler.run(() -> doSomething())
+   ```
+
+### Breaking
+ 
+ - `bindErrorCode` renamed to `bind`
+ - `bindErrorCodeClass` renamed to `bindClass`
+
