The compromise struck at the New York Agreement a few months back was done in order to try to bring an end to the ongoing scaling problems which Bitcoin faces, with some people blaming the 1MB block limit as the cause of the problem. This led to the debate of whether or not scaling should be done via 'on-chain scaling methods' (a block size increase) or via 'off-chain scaling methods' (such as Segwit or the idea of Lightning Network).

There was an agreement, known as 'the Silbert Accord' and 'SegWit2X', with enough mining support and hash power, that miners would start to signal for, and activate SegWit (Segregated Witness) by August. In return, the people that wanted larger blocks than the current 1MB blocks, would receive this at some point in November through enough mining support and hash power in the form of 2MB blocks, increased from 1MB blocks currently. This could potentially result in another hard fork and the consequences this will have, and which chain will be followed are not yet known. However, just like with the recent hard fork, you will likely be given a duplicate of your coins on the other chain, and so this shouldn't be too much of an issue and you will have the choice whether or not to hold these coins.

However, as a result of the recent hard fork, the legitimacy of this agreement has been brought into question, and whether or not it will happen is not yet known for sure, but I personally think that it likely will happen.
