+Big thanks to [DarkLite1](https://github.com/DarkLite1) for some great updates
+* `-DataOnly` switch added to `Import-Excel`. When used it will only generate objects for rows that contain text values, not for empty rows or columns.
+
+* `Get-ExcelWorkBookInfo` - retrieves information of an Excel workbook.

 [Fixed](https://github.com/dfinke/ImportExcel/pull/126) Powershell 3.0 compatibility. Thanks to [headsphere](https://github.com/headsphere). He used `$obj.PSObject.Methods[$target]` snytax to make it backward compatible. PS v4.0 and later allow `$obj.$target`.
