I was looking at the release info for 14 on Our Umbraco and it did not list any breaking changes but I know that the new backend dropped angular and all packages have to have a new UI (which I would consider a breaking change) so I am wondering what else might be breaking in 14? I am on 13 right now and am trying to decide if I should go to 14 when it comes out or just hold off till 17.

Thanks I had not seen that. I was just going off the summary "in progress" page on our umbraco that listed 0 breaking changes. I will give your linked page a read over.
