Released: Apr 16, 2026

Updates in v8.5.2

Features

• Updated System.Security.Cryptography.Xml for .NET 9 and 10 to address a security vulnerability (CVE-2026-26171 and CVE-2026-33116).

Fixes

• ExcelRange.LoadFromCollection: DisplayAttribute.Name was used directly instead of DisplayAttribute.GetName(), causing resource keys to appear as column headers instead of localized values when ResourceType was set.
• ExcelRange.LoadFromCollection: EpplusTableColumnAttribute.Order was ignored when DisplayAttribute was also present.
• Fixed various issues with the LAMBDA function and variable expressions.
• Fixed an issue with the VSTACK and HSTACK functions when the argument is a single-cell range.
• The IFS function did not handle arrays in the condition arguments.
• The SORTBY function now preserves the original order of rows/columns when the sort key is not unique.
• EPPlus will now throw a NotSupportedException if opening workbooks saved in the Strict OpenXML format.
