I upgrades Ubuntu to 19.04, and it appears that the default font in Emacs has changed. Is it just me, or is it an Ubuntu/Debian change? Or has there been a change upsteram?
Also, what is the name of the new font and the previous font?
The splash screen says
This is GNU Emacs 26.1 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.7) of 2019-04-11, modified by Debian
