+- Make allowance for the AutoFilter dropdown icon in the first row of an Autofilter range when using Autosize columns. [Issue #2413](https://github.com/PHPOffice/PhpSpreadsheet/issues/2413) [PR #2754](https://github.com/PHPOffice/PhpSpreadsheet/pull/2754)
 - Support for "chained" ranges (e.g. `A5:C10:C20:F1`) in the Calculation Engine; and also support for using named ranges with the Range operator (e.g. `NamedRange1:NamedRange2`) [Issue #2730](https://github.com/PHPOffice/PhpSpreadsheet/issues/2730) [PR #2746](https://github.com/PHPOffice/PhpSpreadsheet/pull/2746)
 - Update Conditional Formatting ranges and rule conditions when inserting/deleting rows/columns [Issue #2678](https://github.com/PHPOffice/PhpSpreadsheet/issues/2678) [PR #2689](https://github.com/PHPOffice/PhpSpreadsheet/pull/2689)
 - Allow `INDIRECT()` to accept row/column ranges as well as cell ranges [PR #2687](https://github.com/PHPOffice/PhpSpreadsheet/pull/2687)
