I released a new BETA version of ListAttachments for SharePoint 2013 and SharePoint Online.

Changelog BETA1:

• Almost completely rewritten to make it more robust and efficient
• Fixed the issue in IE where the bubble pops up and disappears immediately
• Changed from SOAP to REST to minimize the payload and speed up the whole process of retrieving the required data from the server
• Lots of other little fixes and improvements

Changelog BETA2:

• Fixes a bug where the script fails for Read-Only users because SP.Ribbon.js is initialized too late

You can get the latest version on the Product Page. If you find any bugs, I would appreciate if you’d report them in either the comment section or the forum. Thanks!
