Supporting Windows XP becomes increasingly harder over the years as some of the software used in developing CH becomes incompatible with this system (Visual Studio >2017, InnoSetup 6).
Because of that, in 1.50 WinXP support will be dropped. In addition Windows Vista will be dropped too due to low usage ratio. This will make Windows 7 the lowest Windows version to be supported.
This epic encompasses various upgrades to the code to make it more compatible with newer tools and libraries.
