+### Version 3.2.1-SNAPSHOT:
+
+- Fixed bug in divide operator, that caused:
+ ex: "10/4 = 2, and not 2.5",
+ "5/2 = 2, and not 2.5"
+- Changed RoundinMode from HALF_UP, to HALF_EVEN
+- Changed internal calculation type from BigDecimal to Double
+
+### Version 3.2.0:
+
+<b>IMPORTANT:</b></br>
+Changed package names from
+```java
+    pl.bgora.rpn
+```
+ to 
+ ```java
+ com.github.bgora.rpnlibrary
+ ```
+
+  <b>Fixed bug, that prevented from exucuting functions with multiple parameters.</b>
+
+  <b>New functions:</b></br>
+  max() - takes two parameters, returns greater one</br>
+  min() - take two parameters, returns less one</br>
+  fib() - Fibonacci number</br>
+
+  <b>Refactor:</b>
+
+  Changed <i>createCalulator</i>, and <i> getDefaultEngine</i> to use <i>CalculationEngine</i> interface
