The expectation is that any of those changes you’ve made above would apply immediately and correctly. Hot Reload might be unstable in the promoted 4.8 build as we’ve been making significant changes to the build system in that branch. The 4.8 release has only had minimal QA testing so far, as we’re busy working on the upcoming 4.7 release. I’d suggest testing using the 4.7 preview release – it has had extensive hot reload testing. It’s possible there are some edge cases that we haven’t found yet, but if you can help us reproduce a specific issue I’ll make sure it gets fixed ASAP.
Hot Reload works in 4.6.1 as well, but there were several known issues we discovered and addressed in 4.7. For example, certain changes made in your class constructor would not be applied, and this now works in 4.7.
