You are right, of course, but nonetheless this is a significant step forward for the language (and the ecosystem as a whole).
I do hope that - just like yourself, I am sure - the next significant step is more organically and proactively developed, and not treated (at least in the wider communtity's eyes) as a belated addition to a bewildered leviathan.
Yes, strange for a bug fix to be top of a list of features, however...
I don't agree that it's "not the most eventful" release:- libsodium being included into the core is a big tick in the box in terms of maturing as a language; modern - secure - cryptography out of the box.
Thee "pull-left" and "pull-right" classes were added into v2.2 (in the Github repository) in addition to the similar "float-left" and "float-right" classes.
These additions have been merged into the Master branch this afternoon.
The example site is running on v2.1 which uses the float-left and float-right classes.
Did think about a 24 unit approach, however we concluded it was not the way forward as the unit widths at 24-points would be ok at 4K, but at sub-4K they would be negligible, and the developer would need to work in multiples.
