I believe this is like the third or even fourth time both Israel and Hamas had decided to get up the negociation table and returned again I order to present quote similar demands to each other.
It makes sense to me the State of Israel wants the complete release of thode people, while at the same time, Hamas tries to release as many Palestinian from Israeli prisons with with hostage released from Gaza. It is quite a sick game how both parties are willing to use human lives as mere exchange chips, as if this was a casino or something.

Whatever the case, it is very unlikely Hamas will accept to release all those people, it is one of the few things they have left as leverage to avoid the the IDF to completely wipe out what is left of the Gaza strip.
