We’re still working on finishing VS 2015 RTM, but we’re definitely done with adding new features, so we can publish final feature tables.  Let’s start with the STL, where we implemented a bunch of stuff after publishing 2015 RC’s features<\/span><\/a> in April.  Whenever I mention C++17 below, I’m referring to the current Working Paper N4527<\/span><\/a>.<\/span> <\/p>\n

   \n“2015 opt-in” means that this is guarded by a macro.  By default, we provide auto_ptr\/etc.  If you define _HAS_AUTO_PTR_ETC to 0 project-wide (which you should do via the command line or project file, not via #define), then we won’t provide auto_ptr\/etc.  In the next major version, I’m planning to make this opt-out, and in the major version after that, I’m planning to eliminate auto_ptr\/etc. entirely.  Now would be a good time to start migrating your code.<\/span>\n   \n“N\/A” means that these proposals altered the Standard’s wording, but did not physically affect implementers or users.  I’ve listed them as Not Applicable for the sake of completeness.<\/span>\n   \nHere’s a detailed summary of our status:<\/span>\n   \nOur C99 Standard Library implementation is complete, except for tgmath.h (which is irrelevant in C++) and the CX_LIMITED_RANGE\/FP_CONTRACT pragma macros.<\/span>\n   \nOn top of that, our C++11 Standard Library implementation is complete.<\/span>\n   \nOn top of that, our C++14 Standard Library implementation is complete, except for Expression SFINAE in result_of (N3462<\/span><\/a>) and std::function (LWG 2132<\/span><\/a>), plus 11 more Library Issues.<\/span>\n   \nOn top of that, our C++17-so-far Standard Library implementation is complete, except for pair\/tuple improvements (N4387<\/span><\/a>) and untimed shared_mutex (N4508<\/span><\/a>), plus 10 Library Issues.<\/span>\n   \nAny remaining exceptions are bugs.  (By the way, we’ve fixed roughly 160 bugs in the STL between 2013 and 2015.  A year ago, I listed the first batch of fixes<\/span><\/a>.  I’ll write about the rest of the fixes soon.)  For example, we’ve implemented every occurrence of constexpr in C++17-so-far’s STL, with a very small number of exceptions, which are tracked by DevDiv#1184873\/Connect#1414341<\/span><\/a> and DevDiv#1188232:<\/span>\n   <\/p>\n
