Jolly good! All checks passed, no error tags reported.

build for 4 architectures completed! took hell of a long time :)

All uploaded fine!

I hope they will be fine for you all! 1.6.16 had important security issues.

I see they released .17 in the meanwhile (took me weeks for this png 
upgrade), but it is a minor upgrade and it should be smoother to 
upgrade, let us see first if it works fine.
