 ## Changelog
 
+* v1.0.2 - Improved Constraint Generation
+
+    * **Fixed**:
+
+        * Maximum constraint count requirements are now much easier to satisfy. 
+
+    * **Known Issues**:
+
+        * When two different strategies can deduce the same information, neither strategy will be flagged as required. This can cause puzzles to be ranked as much easier than they really are. This can also make it difficult or impossible in some situations to generate puzzles that require particular strategies.
+
+        * The cancel button can take a long time to stop the generation process of the largest (8x8) puzzles.
+
+        * On rare occasions the generator will detect contradictions in the generated constraints or report other issues with the strategies.
+
 * v1.0.1 - Bugfix  
 
     * **Fixed**:
