 ### Added
 
+- Support for date values and percentages in query parameters for Database functions, and the IF expressions in functions like COUNTIF() and AVERAGEIF(). [#1875](https://github.com/PHPOffice/PhpSpreadsheet/pull/1875)
 - Implemented DataBar for conditional formatting in Xlsx, providing read/write and creation of (type, value, direction, fills, border, axis position, color settings) as DataBar options in Excel. [#1754](https://github.com/PHPOffice/PhpSpreadsheet/pull/1754)
 - Alignment for ODS Writer [#1796](https://github.com/PHPOffice/PhpSpreadsheet/issues/1796)
 - Basic implementation of the PERMUTATIONA() Statistical Function
