 # CHANGELOG
 
+## [4.3.1] – 25 Sep 2024
+
+### Added
+
+* Added a `replace_blanks` filter to the report template engine to replace blank values in a dictionary with a specified string
+  * This filter is useful when sorting a list of dictionaries with an attribute that may have a blank value
+* Added an option in the change search in the findings library to search findings attached to reports (Closes #400)
+  * Instead of matches from the library, the search will return results for findings attached to reports to which the user has access
+
+### Changed
+
+* Changed the serializer for report context to replace null values with a blank string (`""`) to help prevent errors when generating reports
+  * **Note:** This change may affect templates that rely on null values to trigger conditional logic, but most conditional statements should not be affected
+  * **Example:** The condition `{% if not X %}` will still evaluate to `True` if `X` is `None` or `""`
+* Changed the report form to allow users with the `admin` or `manager` roles to change the report's project (Closes #368)
+  * This change allows a report to be moved from one project to another (e.g., you make a copy for a follow-up assessment)
+  * This feature is only available to users with the `admin` or `manager` roles to prevent accidental data leaks
+
+### Fixed
+
+* Fixed an edge case with the Namecheap sync task that could lead to a domain remaining marked as expired after re-purchasing it or renewing it during the grace period
+
