[Gimp-user] Why 2.10.4 not 2.10.6 at my Debian ?

[sebul <sebuls gmail com>]

Hello. I use Debian 9.5

https://www.gimp.org/news/2018/08/19/gimp-2-10-6-released/
says gimp 2.10.6
But

flatpak install https://flathub.org/repo/appstream/org.gimp.GIMP.flatpakref
says
error: App org.gimp.GIMP, branch stable is already installed

flatpak run org.gimp.GIMP -n &
runs GIMP but this gimp version is 2.10.4 not 2.10.6

apt-get install gimp
installs gimp 2.8 not 2.10

How can I run GIMP 2.10.6 ?
