Hello, Orca 3.28 is now available in stretch-backports. You can get it by adding this apt repository line:
deb http://ftp.debian.org/debian stretch-backports main and running apt-get install -t stretch-backports gnome-orca libatk-adaptor which will bring the latest accessibility stack improvements. Just log out and in again to have the whole desktop restart with it. Cheers! Samuel
