And now, I see that MATE should be improved. But what I also see is that kernel is changing its interface in a way that (while making sense) breaks existing application. And we don't break existing applications. [Now... maybe if the fix for the application is available for long long time and noone is really looking and everyone already has new application version, maybe ... But pull request for MATE is 9 days old, and not even merged. So there is no way this is suitable for 4.17.] Pavel --=20 (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blo= g.html --IJpNTDwzlM2Ie8A6 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEYEARECAAYFAlqnB2cACgkQMOfwapXb+vJNjgCgt2WRQHWFzZise9vYRi6ryIvr /a4AoLyqSOQ/14n0JmioxEC265RZ40RT =ak1a -----END PGP SIGNATURE----- --IJpNTDwzlM2Ie8A6--
