C++20 is here! In fact, as we head towards 2022, it’s been here a while. It may surprise some, but we’re only a few months from a freeze on new proposals for C++23! But let’s not get ahead of ourselves. C++20 is a big release - at least the biggest since C++11 - some have said it's the biggest since the first standard in 1998!

From the article:
Another possible surprise is that support for C++20 is currently better in GCC and MSVC++ than in Clang. Nonetheless, significant chunks of the new language and library features are widely available across the three major compilers, already. Many of them, including some less well known features, are there to make common things safer and easier. So we’ve been hard at work implementing analyzer rules to help us all take full advantage of the latest incarnation of “Modern C++”. This is just the start, but we already have 28 C++20-specific rules in the latest releases of all our products (with many more in development).
Let’s take a peek at some of them.
