@@ -9,7 +9,10 @@ The GitHub action to delete workflow runs in a repository. This action (written
 The action will calculate the number of days that each workflow run has been retained so far, then use this number to compare with the number you specify for the input parameter "[**`retain_days`**](#3-retain_days)". If the retention days of the workflow run has reached (equal to or greater than) the specified number, the workflow run will be deleted.
 
 ## What's new?
-* Add the input parameter "[**`delete_workflow_pattern`**](#5-delete_workflow_pattern)". Fill in the specified workflow name, this workflow will be processed, if no workflow is specified, all workflows in the repository will be processed.
+* Add the input parameter "[**`delete_workflow_by_state_pattern`**](#6-delete_workflow_by_state_pattern)" and "[**`dry_run`**](#7-dry_run)". 
+* Add ability to filter workflows by workflow filename (in addition to the name)
+* Add ability to filter workflows by state
+* Add ability to perform a 'dry run' which logs the changes but doesn't perform the actual deletion.
