 ## Release notes
 
+### 0.6.0
+
+- The ability to restrict file browsing to a `sandbox_path` folder has finally been added!
+- Filenames can not contain path separator characters or parent folder strings (i.e., '..')
+- `use_dir_icons` has been replaced with `dir_icon` which allows for customizing the folder icon
+- `dir_icon_append` can now be used to put the folder icon before or after the folder name
+- Better error handling with `ParentPathError`, `InvalidPathError`, and `InvalidFileNameError`
+- Better and more consistent handling of Windows drive letters and paths
+- Select button is now properly activated again when applying a selection or resetting the filechooser
+
+
