Conan, the C and C++ package manager, is now part of GitLab
Conan users can now set GitLab as the remote registry for their packages
From the article:
This allows users to share private packages within an organization that is already using GitLab, publish public packages for general or open source use, and will open up many possibilities in utilizing GitLab’s CI pipelines to build and consume these packages automatically.

Full of novelty.
LLVM/Clang 10.0.0 is released!
From the article:
Some highlights include:
- C++ Concepts support in Clang
- Clang no longer runs in a separate process by default ("in-process cc1")
- Windows control flow guard (CFG) checks
- Support for more processor cores and features

Recently, the PlatformIO development environment of embedded systems has supported PVS-Studio. In this article, you'll find out how to check your code with the static analyzer on the example of open project.
PVS-Studio Integration in PlatformIO
by Alexey Govorov
From the article:
In the /arduino/AP_Utils/examples/ directory, there are several examples of programs for configuring and running the hexapod, we'll use servo_test.ino. Basically, the program for Arduino is created as sketches in the INO format, which in this case is not quite suitable. In order to make the correct .cpp file from it, it is usually enough to change the file extension, add the #include <Arduino.h> header at the beginning, and make sure that functions and global variables are declared before accessing them.

The STE||AR Group has released V1.4.1 of HPX -- A C++ Standard library for parallelism and concurrency.
HPX V1.4.1 Released
The newest version of HPX (V1.4.1) is now available for download! This is mostly a bug-fix release that fixes problems found in the previous HPX V1.4.0. Please see here for a full list of resolved issues.
HPX is a general purpose parallel C++ runtime system for applications of any scale. It implements all of the related facilities as defined by the C++ Standard. As of this writing, HPX provides the only widely available open-source implementation of the new C++17 parallel algorithms. Additionally, HPX implements functionalities proposed as part of the ongoing C++ standardization process, such as large parts of the C++ Concurrency TS, Parallelism TS V2, data-parallel algorithms, executors, and many more. It also extends the existing C++ Standard APIs to the distributed case (e.g. compute clusters) and for heterogeneous systems (e.g. GPUs).
HPX seamlessly enables a new Asynchronous C++ Standard Programming Model that tends to improve the parallel efficiency of our applications and helps reducing complexities usually associated with parellism and concurrency.

CLion starts 2020.1 Early Access Program: improvements to Clang-based tools and debugger, new font and editor theme, and more
by Anastasia Kazakova
From the article:
We’ve got a lot planned for 2020 and 2020.1 and now it’s time to start our regular Early Access Program!
EAP builds are free and give you a preview of the upcoming changes and enhancements. They might not be stable and might contain functionality that doesn’t make it to the final release. And if you decide to try these builds, please, inform us of any issues you run into or any inconveniences you experience as early as possible, so we have time to investigate and can try to address them before the release...

C++ Modules conformance improvements with MSVC in Visual Studio 2019 16.5
by Cameron DaCamara
From the article:
C++20 is right around the corner. Along with the new standard comes the much anticipated Modules feature! The compiler team initially announced that we were working on the Modules TS back in 2017 and since then we have been hard at work improving the feature and improving compiler conformance around this feature. We finally feel it is time to share some of the progress we have made on the conformance front for Modules...
