Spread.NET V11 Released

Spread.NET 11 is here!

I'm happy to announce that the new release of Spread.NET 11 (formerly Spread Studio) is now available! All developer licenses for Spread.NET 11 now also include a full year of maintenance support.

This release features many important changes to the Windows Forms controls, all focused around improved performance and memory footprint, along with many other enhancements to make this the most powerful spreadsheet user interface control ever released.

Performance Improvements

Spread.NET can handle your biggest, most complex spreadsheets, faster than ever before, and using less memory too – performance improvements up to 80% faster and using a fraction of the memory! Spread.NET 11 can import, export, and calculate your Excel documents faster than ever before.

462 functions now available

We've added more than 130 new calculation functions, bringing the total number to 462, more than any other spreadsheet solution. New support for array formulas (entered using Ctrl+Shift+Enter) enable advanced matrix and array calculations. The new CircularFormula event fires to inform the developer when the user enters a formula which creates a circular reference.

New workbook protection support allows you to set a password to protect the workbook structure and prevent the user from deleting or reordering sheets.
