It was announce that they're implementing 2mb blocks while segwit2x is being cancelled and that's about it for now. I think this one is unnecessary as you need to have scaling issues to scale.
https://coinjournal.net/dash-releases-software-upgrade-cheaper-transactions-now-listed-huobi-pro/With regards to your remarks about needing to have scaling issues to scale i think thats very short sighted. Better to think and plan ahead then to get overwhelmed
with increased volume and then need time to find the solution.
I also think we are seeing a split in the cryptomarkets between cryptocurrencies that function as value of store (Bitcoin) and cryptocurrencies that function as value of usebility (Dash, Bitcoin Cash).
The differentiator here beeing both larger blocks and lower fees.
But wait dash is centralised junk and a scam
Variable block size has been available on many alts before bitcoin cash thought they would copy the idea.
You want usability ??there are far better options and many of them.
If you want usability and large (real not ver induced faux volume) LTC is better than both.
What we are seeing here is whales trying to gain more wealth from others by force.
