Has template naming changed in Kirby 3?

While trying to migrate my site from K2 to K3 I came across this issue: the content of my (start) page is named “home.de.txt”. (There is no “home.en.txt” yet, but I wanted to be prepared…)
In K2 this page worked flawlessly with a template named home.php.
In K3 it uses the default.php template though instead of home.php. I tried renaming the template to home.de.php and that seems to work.
Can someone say something how to correctly name content and template files in Kirby 3? Has it changed compared to Kirby 2?

Thanks
Matthias

Don’t rename the template. Have you enabled languages in the config?

Sonja, Thanks for the quick reply.
