I think we need to discuss the changes that go into release 2.5 at this time.

FYI, thanks for this. I think this is causing msh3 to fail to build on the latest atm.

It seems strange to me to have an API change that is going to ship in v2.5.1, which is a patch version.

On the one hand, some changes leading to it have already been cherry-picked. On the other hand, we could also very easily create a v2.6.

Opinions?

I don't want to break the rules around semantic versioning unless there's a really good reason, but I need to make sure the partners who requested this feature can go with 2.6 or if they need it in 2.5. I think they need it in 2.5.
