ReoGrid Web 1.3 is here. A single grid now becomes a workbook of multiple worksheets — with a standard sheet tab bar, per-sheet undo history, whole-workbook xlsx/JSON I/O, and cross-sheet formula references like =Sheet1!A1. No breaking changes to the public API, and multi-sheet works on both the Lite and Pro editions.

Starting with ReoGrid for .NET 4.5, an official NuGet feed is available. Licensed customers can create an authentication token in the customer portal and install or update ReoGrid directly from Visual Studio.
