Presumably there are “alternates” if there are objections to a specific person being released. One of the conditions is that no one who was convicted of murder will be released, so it may include someone who only gravely injured someone, rather than actually killed someone.

If you can find the list you can search each name. There well likely be some news articles about each one.

EDIT:

The full list (in Hebrew) is here: https://www.gov.il/he/Departments/DynamicCollectors/is-db

Israeli press is already raising some objections to those who were being held for attempted murder - including one woman who repeatedly stabbed a mother in front of her kids.
