-*  Fixed bug in `UUID` field that was trimmed to 32 chars instead of 36 (with dashes).
-*  Since first 32 characters of uuid should still be unique I consider this as non-breaking, but if you

+*  **Breaking** Changed `UUID` field that was trimmed to 32 chars (without dashes) instead of 36 (with dashes) 
+   to more in line with other libraries.
