I only got into Concrete CMS development during the 8.x → 9.x transition but quickly found the built-in LESS integration handy and reliable. It’s just that the included less.php version (1.8.x) is pretty ancient and I find myself using a lot of ~"" wrapping, duplicating vars in LESS and native CSS and generally not being able to use nice new CSS features because the compiler isn’t aware of them.
Is it that LESS is now deprecated and we shouldn’t be expecting updates to less.php or are there plans to get it up to speed at some point?
