If I move from boost::thread to std::thread then yes, I'm expecting some costs moving. But merely 'upgrading' Boost, which might not require any action from the developer himself, should not come with such costs.
I agree with you, and I believed that letting the user 3 releases to move to the new behavior was enough. It seems that I was wrong.
I can't comment on the specifics of the breaking change, but on the topic of "3 releases is enough": with quarterly releases, this is only 9 months which is very short, IMHO. I would guess that many clients of boost upgrade maybe once a year or so --- in large part due to the fact that Boost does not maintain a stable API as described elsewhere in this thread by Artyom Beilis --- and thus would not see the deprecation period at all. Certainly users of a linux distribution like Debian/Ubuntu would never see this transition because we release every 1.5 - 2.5 years. My suggestion is that a deprecation period be measured in years, say 2-3 years. Regards, -Steve
