C++20 Approved -- Herb Sutter

C++20 passed unanimously, on track to publish later this year.

C++20 Approved

by Herb Sutter

About the article

On Friday September 4, C++20’s DIS (Draft International Standard) ballot ended, and it passed unanimously. This means that C++20 has now received final technical approval and is done with ISO balloting, and we expect it to be formally published toward the end of 2020 after we finish a final round of ISO editorial work.

As always, we are not counting on ISO’s publication speed to call it C++20, it’s C++20 because WG21 completed technical work in February. If for some reason ISO needs until January to get it out the door and assigns it a 2021 publication date, the standard will still be referred to as C++20. That is already its industry name, and 300,000+ search hits can’t be (retroactively made) wrong!

"C++ Move Semantics - The Complete Guide" now Feature Complete -- Nico Josuttis

The new book by Nico Josuttis is now available as an ebook draft.

C++ Move Semantics - The Complete Guide

by Nico Josuttis

About the book:

Having 200 pages, the description of move semantics is feature complete now. Only a few chapters about the use of move semantics in the C++ standard library are missing.

The book teaches all aspects of C++ move semantics. Starting from the basic principles it motivates and explains all features and corner cases (such as perfect returning with decltype(auto)) so that a C++ programmer can understand and use move semantics right in application code, when implementing classes, in generic code, and in foundation libraries.
