Towards INN 2.6.4 release

[Julien ÉLIE]

Hi all,

Our last release dates back to 2 years (time goes fast!).  Not many 
changes, no major fixes but a few minor improvements or bug fixes.
I believe it is worthwhile releasing INN 2.6.4 for instance in early 2021.

Any patch you would like to include?
Any annoying bug you're facing?
