     <li>FIXED: color palettes with few entries (i.e. "step"-palettes) were not applied correctly</li>
     <li>FIXED: fixes strange rendering with distortions (especially in text!), by correcting size calculation of internal image buffer</li>
     <li>FIXED: exporting gridPrinting plots when using only a JKQTBasePlotter</li>
+    <li>FIXED: fixed impleentations of JKQTPlotter::beginGraphs(), which actually returned the end-iterator (COPY-PASTE-ERROR!!!)</li>
     <li>REORGANIZED: separated line-graphs from jkqtpscatter.h/.cpp into jkqtplines.h/.cpp</li>
     <li>IMPROVED: QT6-compatibility by removing deprecated warnings</li>
     <li>IMPROVED: added missing override declarations</li>
