To summarize blocks greater than 90mbs is causing the network to have issues.
Monero previously did not have a block size limit in order to keep it scalable, cheaper fees, faster transactions, more data.
But they're proposing adding a temporary hard cap in order to allow time for the issue to be fixed.
Without 90mb cap, transactions are limited to 12 million a day.
There seems to be a concensus around adding a temporary cap to give a 5 year extension to fix the issue.
Unless someone fixes it sooner than that, and it's implemented in the next update, in which case they won't add the block cap.
Here's a link that shows some of the dev discussion regarding this.
