## AI overview

A 2020 retrospective on ReactOS reports bug fixes, new instabilities, full-time kernel hires, shell improvements, RAPPS application-manager enhancements, and upgrades to its compiler and build tooling. It covers GCC 8.4, CMake 3.17, restored Clang CI builds, reduced older MSVC support, and a move to the C99 standard.

This year we hired two kernel developers full-time, this happened for the first time in the project's history. The post highlights some of the changes which may be interesting to the community. Shell changes Shell hasn't seen much attention recently, due to most of the work being concentrated in the kernel, but there are still some useful fixes and feature implementations:
