On behalf of the Haxe Foundation, we are proud to announce the official release of the Haxe 4.0.0-rc.1! It is available along with the changelog at https://haxe.org/download.
The main new feature of this release is an experimental null-checker, which can be enabled for individual packages from command line by using
--macro nullSafety("package.path") . We will post more information on this soon!
