+* Removed reference to EPPlus.System.Drawing for primary image and text handlers. The generic handler is now used for all target frameworks.
+  You can still use these handlers by referencing the EPPlus.System.Drawing handlers nuget package and use the 'SystemDrawingTextMeasurer' or 'SystemDrawingImageHandler' classes as primary handler.

 # Features / Fixed issues - EPPlus 7
+## Version 7.6.0
+* Added target framework .NET 9. 
+* Removed out of support frameworks, .NET 6 and .NET 7.
+* Fixed an issue handling formulas when sorting a range.
+* Insert row in table caused corrupt workbook.
+* A workbook could lose styles if the ExcelPackage.FullPrecision property was set.
+* When copying a worksheet, drawings would be resized after inserting rows. This was caused by drawings being copied before styles and therefore drawings would not be aware of any styles.
+* Set Active Tab did not work correctly, if 'CompatibilitySettings.IsWorksheet1Based' was set to true.
+* Fixed "Part already exist" error when copying images between workbooks that already have images.
+* Fixed another issue when copying ExcelPicture’s between workbooks.
+* Iteration of worksheets indexed incorrectly in rare cases. EPPlus now throws an InvalidOperationException, if the collection has been altered under an enumerable operation.
+
 ## Version 7.5.3
 * Improved COUNTIF performance, if full column addresses was used.
 * If having a workbook with no reference to a font in the styles.xml, caused an corrupt workbook.
