+  * Renamed data type `ChartLineType` to `LineType`
+  * Renamed data type `ChartLine` to `LineOptions`
+
+### Security
+
+* Check row number when reading worksheet to prevent unbounded memory allocation (CVE-2026-54063), related security advisories [#GHSA-h69g-9hx6-f3v4](https://github.com/xuri/excelize/security/advisories/GHSA-h69g-9hx6-f3v4)
