Yep, there’s release notes here:

You can usually expect breaking changes when the version’s major revision changes, eg from 2.5.x.x to 2.6.x.x or from 2.6.x.x to 2.7.x.x. Sometimes they’re small and unnoticeable to the average user, other times there’s been some upgrade to instance templates, requiring some shuffling. 2.6 was a big one, with AMP going from .NET 4.6 to .NET 8, so I’d expect the next one to be a bit tame in comparison.
There’s also announcements in the Discord related to any large breaking changes.
