From 2027, the winning broadcaster will automatically be ineligible to host the following Eurovision Song Contest if an armed conflict, a sensitive geopolitical situation or another situation materially affects the security, safety or stability of the country or its immediate region.

If the winning broadcaster is unable to host, the EBU will appoint an alternative Host Broadcaster.

The EBU has also clarified the rules regarding live vocals and pre-recorded elements.

The main principle remains unchanged: The Lead Singer or Lead Singers must perform the main melody live.

Backing tracks and pre-recorded elements can still be used in accordance with the rules, but the lead vocal must be the only element performing the main melody.

From 2027 all artists must be at least 18 years old on the day of their first rehearsal.

The rules concerning the Semi-finals have also been clarified. Qualification is now described as being primarily determined by the audience vote, including the Rest of the World vote. The rules also allow jury points to be included alongside the audience vote in the Semi-finals, subject to approval by the Reference Group and using a ratio determined by the EBU.

So what's new? Based on the new rules, it seems Ukraine still wouldn't get to host at home, while Israel would.

I think the new rules specifically are designed to prevent Israel from hosting the event, since they're in a "sensitive geopolitical situation", while still keeping them in the competition.

I think the new rules could mean that Israel doesn't get to host either. But you are right. This part changes very little. It's mostly just codifying a rule that was already in effect but wasn't written down before.

The other changes however are actual changes. The minimum age for participation was 16, now it's 18. And juries in the semis are now less powerful.

There might be some more changes coming in the next couple of months. Some outlets are reporting that the EBU is considering a new voting system where viewers rank their top three acts. Such a system would likely reduce the televote points of Israel

The situation also has to materially affect the country, but they'd probably argue Israel keeps itself safe and secure.

Why would they? Keeping Israel in the contest is one thing. That's just politics. Having them host is a whole different beast. Suddenly it's logistics. You have to guarantee the security of roughly a 100 thousand visitors (3x3 shows with up to 15k visitors each + press, talent and delegations). What if Hisbollah manages to hit a target in Tel Aviv during the week. Do you really want to take the risk? For a couple of political points?

Sensitive geopolitical situation is a bit vague.
