Comment 12 for bug 1655782

@Iain: The nature of the changes between 2.17 and 2.19 can be viewed here:

https://cgit.freedesktop.org/xkeyboard-config/log/

And the complete diff is in the PPA:

https://launchpadlibrarian.net/306582771/xkeyboard-config_2.17-1ubuntu1_2.19-1ubuntu1~ppa2.diff.gz

It's to a large extent additional layouts/variants, and such changes don't at all affect the commonly used layouts for the big countries. There are also a few specific bug fixes. Please note that we are talking about data (the binary package xkb-data).

xkeyboard-config 2.19 is in Stretch. FWIW I have used it myself for a couple of months. :) I'd say that the regression risk is very low.
