• Multitenancy support through custom data and security extensions
• Support for SQL Server 2008 R2 and Windows 7
• Intelligent data discovery and cleansing of table and field names
• Blank value matching in filters and conditional formatting
• Ability to add links and drill-through to charts and indicators
• Improved date search and caching for OLAP data sources
• Improved editing of field width and font formatting

In the next few months we’ll be working on support for Oracle data sources; a configurable meta layer for field names, formatting and joining; and dynamic filters such as this week and year to date. Watch this space…
