+
+## Features
+
+* add `get_or_none(**kwargs)` method to `QuerySet` and `QuerysetProxy`. It is exact equivalent of `get(**kwargs)` but instead of raising `ormar.NoMatch` exception if there is no db record matching the criteria, `get_or_none` simply returns `None`.
+  
+## Fixes
+
+*  Fix dialect dependent quoting of column and table names in order_by clauses not working
+   properly in postgres.
