What has changed in Hamas's stance regarding hostage releases and the ceasefire deal?

According to the clip, Hamas has reversed its previous position on hostage releases. Last week, Hamas had threatened not to release hostages over the weekend, claiming Israel wasn't upholding its end of the ceasefire deal by delaying the return of displaced Palestinians to northern Gaza. Now, Hamas has announced the planned release of six Israeli hostages while also confirming the deaths of four others, specifically the Bibbas family. This shift represents a significant change in Hamas's approach to negotiations amid the ongoing tensions in the Middle East.
