 ## [1.3.3](https://github.com/layoutBox/FlexLayout/releases/tag/1.3.3)
 Released on 2018-02-28
 
 * Fix Yoga's rounding issues
    * Integer truncation of sizes calculated by sizeThatFits:, and utility functions. Introduced by Obj-C -> Obj-C++ conversion in previous PR
    * Low coordinate rounding threshold, which results in flooring apparently valid values. Layout becomes very wrong with absolute coordinate values larger than 100 and having pointScaleFactor set to 3.

 ###### Example:
 This example creates a flexbox container and sets its alpha to 0.8.
 
 ```swift
     view.flex.direction(.row).padding(20).alignItems(.center).define { (flex) in
         flex.addItem().width(50).height(50).define { (flex) in
-            flex.view.alpha = 0.8

         }
     }
