v4.7.7 release

v4.7.7 has three bug fixes and three new features.

Significant improvements

• A new permission ImageEditor was added for access to the image editor.
• The Shelf now includes only those content types that can be added to the current asset in the content edit form. For example, if a content edit form has a single field for a list of videos, the editor can configure the Shelf to include only videos.
• The Java Server Page map.jsp was migrated to the MapFormInput class.

Significant defects addressed

• Corrected an issue that threw a NullPointerException error when importing a list of tags or sections from a Google Sheet.
• Corrected an issue that prevented an image from appearing in an article's lead field. Specifically, this error occurred when modifying an image's crop for a particular size, and the browser window was resized to trigger the crop, but the cropped image did not appear.
• Corrected an issue that flashed an extraneous message when closing the Edit GraphQL Explorer Options widget.
