[phone] v1.04.0
+
+   Added support for "stacked" and "percent_stacked" Line charts.
+
+   Fix for worksheet objects (charts and images) that are inserted with an
+   offset that starts in a hidden cell.
+
+   Removed error in add_worksheet() for sheet name "History" which is a
+   reserved name in English version of Excel. However, this is an allowed
+   worksheet name in some Excel variants so the warning has been turned into
+   a documentation note instead.
+
+
[phone] v1.03.0
+
+   Fix for duplicate images being copied to an Excel::Writer::XLSX
+   file. Excel uses an optimization where it only stores one copy of a
+   repeated/duplicate image in a workbook. WriteXLSX didn't do
+   this which meant that the file size would increase when then was a large
+   number of repeated images. This release fixes that issue and replicates
+   Excel's behaviour.
