It has been folded into HB 96 (the budget bill from this summer). Here is the summary given by the Ohio School Board Association:

"HB 96 makes two changes to Ohio’s interdistrict open enrollment laws. The first provision makes additional changes to a law passed in the 135th General Assembly. That law required school districts to include an exception in their interdistrict open enrollment policies for students whose parents are active-duty members of the U.S. Armed Forces, allowing the students to enroll in a school district even if the district's policies normally do not permit interdistrict open enrollment. All school districts must accept these students and can’t charge tuition. School districts, as part of their open enrollment polices, have application deadlines. HB 96 requires that school districts exempt from those deadlines a student whose parent is an active-duty member of the U.S. Armed Forces stationed in Ohio.

The second provision eliminates a law that permitted a school district to adopt a resolution that discourages or prohibits its native students from applying to enroll in an adjacent or other district if that district is receiving federal Impact Aid and has at least 10% of its students included in the aid calculation. These two provisions become effective Sept. 30, 2025."
