From the discussion about abi compatibility when the Boost.System library is compiled e.g. in c++03 mode and then included in a c++11 project or vice versa (https://groups.google.com/forum/#!topic/boost-developers- archive/EWG5NVOZo_ g)

When can we drop C++03 support? :D

What about the first or second release in 2020 ?

Please define what is meant by "dropping C++03 support

For me it means that - a contributor can use c++11 language and library features (be it the library maintainer or someone else opening a PR on Github) - A user (external or internal) may no longer expect a boost library to compile with a compiler not supporting c++11 (and we can have a discussion just which compilers that are) or when he tries to compile it in c++03 language mode (e.g. -std=c++03) Is that definition precise enough? What other definition did you have in mind (if any)? If that is your concern: I would certainly not expect that you start ripping out the guts of an old, battle proven library and replace everything with c++11 features just for the fun of it. However, next time a feature is added or a bug has to be fixed, you no longer have to restrict yourself to c++03. And maybe, over time, some people will contribute patches that simplify / improve a library by replacing some complex c++03 solutions with simpler c++11 solutions when applicable. Best Mike
