The OneDrive for Windows Phone app has seen a significant update to version 4.5.
New in the latest version is user experience update and improvements, a new All Photos view, access to your Recycle Bin, so that you can view and restore personal and work items, a new page for viewing the properties of personal file, Shared with Me and Recent views for work accounts, search updates for personal and work accounts, easy access to app ratings from the settings menu and the usual bug fixes and performance improvements.
The update gets rid of much of the junk that was in the hamburger menu in the last version, and also makes the OneDrive for Business option much less intrusive.
Overall it is a significant improvement over the last version, which had attracted so much ire.
