I'm struggling to find any kind of migration guide on what breaking changes there might be between v3 and v4. Can someone point me in the right direction so I can upgrade smoothly? We use LESS pretty extensively and ferreting out all the possible changes is usually pretty tricky without any kind of guide or documentaton.

Maybe you can review less.js changelog and github releases

@calculuschild The main change is the default from math: 'always' to math: 'parents-division'. This prevents evaluating math when using / as a valid CSS list separator.
