The version "2.2.11" in About... dialog of 2.2.12.
images/bluefish-splash-nb3.svg and images/bluefish-splash-nb3.png have old numbering.
Attached is the patch for SVG, for version 2.2.12. Change of numbering is necessary if the target postpones to 2.2.13.
PNG has different source I believe since PNG has slight wider viewpoint in smaller size than SVG.
This has been fixed. The ticket is going to be closed.
