Oh. And while I am (still) in vacation WordPress has released his major upgrade, WP 4.1 Dinah. Which includes the new default theme, Twenty-Fifteen (the demo is here, some background here, codex here), “distraction-free” writing mode and other features.
For now, I have updated WP to the new version, still leaving Twenty-Fourteen as a theme. Next year (well, tomorrow) I will see.
