-> **WARNING**: We finally made it to a stable `coloraide` 1.x.x release,  
-> but some more unforeseen changes had to be made. This has been a long  
-> road to get the underlying color library to a stable state.
->
-> - User created custom plugins may need refactoring again, but most
->   should be unaffected.
-> - If you tweaked the new`add_to_default_spaces`, please compare against
->   the default list as some plugins were renamed and user settings may
->   need to get updated. Color space plugins that do not properly load
->   should show log entries in the console.
-
-- **NEW**: Upgraded to the stable `coloraide` 1.1. This should hopefully  
-  eliminate API churn as it is now a stable release.
-- **NEW**: Log when default color space loading fails.
