I skipped revision 3 because I ordered the board and very shortly after that I ordered revision 4.
In revision 4 I made following changes 

I selected the KPTL-3216SURCK-01 LED from Kingbright. According to the datasheet it has 550 mcd at 20mA, so more than the Wurth 150060RS75000 which has 250 mcd. 

What I've learned from this redesign
