My CppCon 2020 talk, “C++20 STL Features: 1 Year of Development on GitHub”, is now available on YouTube. The slides are available on GitHub as PDF and original PPTX. The talk contains complete examples (not snippets!) of several C++20 features: integer comparison functions, constexpr algorithms, uniform container erasure, atomic_ref, and span. ...

What's New We've been busy implementing C++20 features in MSVC's compiler and Standard Library, and migrating the latter to microsoft/STL on GitHub - in fact, we've been so busy that we haven't posted a C++ toolset changelog since the VS 2019 16.0 toolset changelog. So, here are the compiler features and STL features/fixes that have shipped for pr...

Today at CppCon 2019, we (the MSVC team) announced that we're releasing our implementation of the C++ Standard Library (also known as the STL) as open source. https://github.com/microsoft/STL is our new repository, containing all of our product source code, a new CMake build system, and a README with more information. As it explains, we're still...

Visual Studio 2019 version 16.0 is now available and is binary compatible with VS 2015/2017. In this first release of VS 2019, we've implemented more compiler and library features from the C++20 Working Paper, implemented more overloads (C++17's "final boss"), and fixed many correctness, performance, and throughput issues. Here's a list of the C++...

Class Template Argument Deduction (CTAD) is a C++17 Core Language feature that reduces code verbosity. C++17's Standard Library also supports CTAD, so after upgrading your toolset, you can take advantage of this new feature when using STL types like std::pair and std::vector. Class templates in other libraries and your own code will partially benef...

Technology advances by inventing new ways of doing things and by discarding old ways. The C++ Standardization Committee is simultaneously adding new features and removing old features at a gradual pace, because we've discovered thoroughly better ways of writing code. While feature removals can be annoying, in the sense that programmers need to go c...

VS 2017 RTM will be released soon. VS 2017 RC is available now and contains all of the changes described here - please try it out and send feedback through the IDE's Help > Send Feedback > Report A Problem (or Provide A Suggestion). This is the third and final post for what's changed in the STL between VS 2015 Update 3 and VS 2017 RTM. In t...
