abolition of mandatory life imprisonment for murder and treason;
changes to the dangerous offender provisions so that the courts are required to sentence a person declared a dangerous criminal to a term of imprisonment;
giving persons declared to be dangerous criminals the right to apply for discharge of the declaration; and
allowing lifers and dangerous criminals the right to apply for resentencing.
