I’ve just seen this warning when building my site:
DEPRECATION WARNING on line 7 of /XXXX//themes/alpha-church/assets/scss/libs/_breakpoints.scss:
!global assignments won't be able to declare new variables in future versions.
Consider adding `$breakpoints: null` at the top level.
The code raising the warning is found here (I maintain this theme)
Can someone please point me to documentation to help me understand what needs to be done to maintain forward compatibility?
The !global flag may only be used to set a variable that has already been declared at the top level of a file. It may not be used to declare a new variable.
Thanks @zzo. Those docs were very helpful, and I’ve pushed an update to the theme which seems to work—at the very least, it resulted in no changes to the compiled CSS and no further warning messages.
