Note: See the release notes for 13.25.1 for information [how to try the new SFTP code](https://resource.dopus.com/t/directory-opus-13-25-1-beta-how-to-try-the-new-sftp-code/60469/2).

### Preferences

- Added **Preferences / File Displays / Folder Expansion / Expand with mouse wheel over expand button** option. When enabled, you can expand/collapse folders by turning the mouse wheel while hovering over the expansion button.

- Added **Preferences / Miscellaneous / Advanced / thumbs\_disable\_internal** to disable internal image formats for thumbnails (similar to older viewer\_disable\_internal for viewers).

### SFTP

- New SFTP code now goes to the server's initial/home directory on connection, if no initial directory is specified in the FTP Address Book.
- New SFTP code is now enabled by default.
- New SFTP code, if it can't load a private key, now reports more detail to the FTP Log.

### Scripting

- Added `StringTools.FormatAs()` method. Allows a value to be formatted in the same way as the evaluator's`As` operator. For example, `FormatAs(109283832, "size")` returns "104 MB".

### Miscellaneous / Fixes

- Improved aborting scripts with detached dialogs from the Task Manager.
- Fix for context menu items in submenus added in a particular (using SubCommands rather than ExtendedSubCommands) way in the registry not working when selected.
- Fixed duplicated context menu items when right-clicking a toolbar favorite in a sub-folder and then right-clicking a branch or the toolbar background.
- Fixed long delay if you switched back to the old SFTP code and loaded a layout (or previous windows) that contained SFTP paths.
- Fixed button-menus being created instead of simple buttons when dragging commands like Delete (which have a button-menu on the default toolbar) from the Commands tab.
- Fixed Rename crash if a code like {name|noext} was used in the new name field.
- Fixed a couple of issues with /\* \*/ style comments in functions.
- 7z.dll updated to 26.03
