OJS 3.2.1.1 ships with an ancient version of the Less compiler (1.7.13 or so). Meanwhile there is version 3.0.0 which is much better (deals well with “calc”, for example).
Is there a clean way in which I could install a newer version of the wikimedia/less.php via, say, a plug-in, and OJS would then use it? I’m interested in a way that would survive the core upgrades.
