+# [v2.1.6 (v.2.1.6)](https://github.com/AleksandrRogov/DynamicsWebApi/releases/tag/v.2.1.6) - 10 Sep 2024
+
+**Changes**
+- :warning: Deprecated: `fieldName` in request properties for `deleteRecord`, `uploadFile`, `downloadFile`. Please use `property` instead.
+- Curly brackets won't be removed from the GUIDs inside `filter` if the value that contains the GUID is inside single quotes, which means it's a string. This is an improvement of an existing functionality.
+Before: `"attribute eq 'some text {GUID} more text'"` would result in `"attribute eq 'some text GUID more text'"`
+Now: `"attribute eq 'some text {GUID} more text'"` stays the same `"attribute eq 'some text {GUID} more text'"`
+- Improving performance by pre-compiling and optimizing regular expressions.
+- General refactoring to improve code readability.
