 # Change Log
 
+## [1.5.0](https://github.com/mirego/PinLayout/releases/tag/1.5.0)
+### New method `sizeToFit(:FitType)` & `fitSize()` is now deprecated
+
+Changes:
+
+* BREAKING CHANGE: **`fitSize()`** is now deprecated. The new `sizeToFit(:FitType)` should be used instead.
+
+* New method **`sizeToFit(_ fitType: FitType)`**  
+	* **`sizeToFit(_ fitType: FitType)`**  
+	The method adjust the view's size based on the view's `sizeThatFits()` method result.
+	     PinLayout will adjust either the view's width or height based on the `fitType` parameter value.
+	     
+	     Notes:
+	     * If margin rules apply, margins will be applied when determining the reference dimension (width/height).
+	     * The resulting size will always respect `minWidth` / `maxWidth` / `minHeight` / `maxHeight`.
+	     
+		**Parameter `fitType`:** Identify the reference dimension (width / height) that will be used to adjust the view's size.  
+	
+	 * **`.width`**: The method adjust the view's size based on the **reference width**.
+	        * If properties related to the width have been pinned (e.g: width, left & right, margins, ...), the **reference width will be determined by these properties**, if not the **current view's width** will be used.
+	        * The resulting width will always **match the reference width**.
+	     
+	 * **`.height`**: The method adjust the view's size based on the **reference height**.
+	         * If properties related to the height have been pinned (e.g: height, top & bottom, margins, ...), the **reference height will be determined by these properties**, if not the **current view's height**  will be used.
+	         * The resulting height will always **match the reference height**.
+	     
+	 * **`.widthFlexible`**: Similar to `.width`, except that PinLayout won't constrain the resulting width to match the reference width. The resulting width may be smaller of bigger depending on the view's sizeThatFits(..) method result. For example a single line UILabel may returns a smaller width if its string is smaller than the reference width.
+	     
+	 * **`.heightFlexible`**: Similar to `.height`, except that PinLayout won't constrain the resulting height to match the reference height. The resulting height may be smaller of bigger depending on the view's sizeThatFits(..) method result.
