SUMMARY

After upgrading to version 5.25, themes no longer work for the lock screen.
The lock screen will always use the default theme.

STEPS TO REPRODUCE
1. Upgrade to 5.25
2. Using or switch to a theme with lock screen theme (e.g. Nova)
3. Lock the screen

OBSERVED RESULT

It is always the default lock screen (with changed highlight color, though).

EXPECTED RESULT

Use the lock screen from the theme.

There was an API break, documented on plasma-devel.
Themes can set their metadata to v2 when supported

Thanks for the information! I was thinking of this possibility, but did not find any posts mentioning this.
Could you please point me to where this is mentioned and/or documented (esp. where should I look for for future updates)?
