From Adam Wead:

It gives me great pleasure to formally announce the release of the Hydra gem Sufa, version 4.0.  This release marks the culmination of 5 months’ work of collaborative development with the members of Penn State’s Services and Solutions team and Digital Curation Experts (DCE).

This new version includes a complete redesign of Sufia’s user interface, based on user feedback and design studies conducted with the staff and faculty at Penn State University.  Sufia’s features now include:

• Multiple file, or folder, upload
• Flexible user- and group-based access controls
• Transcoding of audio and video files
• Generation and validation of identifiers
• Fixity checking
• Version control
• Characterization of uploaded files
• Forms for batch editing metadata
• Faceted search and browse
• Social media interaction
• User profiles
• User dashboard for file management
• Highlighted files on profile
• Sharing w/ groups and users
• User notifications
• Activity streams
• Background jobs
• Single-use links
• Google Analytics for usage statistics
• Integration w/ cloud storage providers
• Google Scholar-specific metadata embedding
• Schema.org microdata, Open Graph meta tags, and Twitter cards for rich snippets
• User-managed collections for grouping files
• Full-text indexing & searching
• Responsive, fluid, Bootstrap 3-based UI
• Dynamically configurable featured works and researchers on homepage
