Haxe 5.0 preview.1 has been officially released

Release Notes

Dear Community,

On behalf of the Haxe Foundation, we are proud to announce that Haxe 5.0.0-preview.1 is now officially released! Check out the changelog below for more information.

As a preview release, it should not be considered stable and does, in fact, have some known issues. However, we appreciate anyone testing this version as it is going to ultimately help with the real Haxe 5 release. If you have any suggestions or run into any problems, feel free to open an issue on GitHub.

Thanks to everyone involved!

Note: if you are getting this error:

Uncaught exception - is not a valid version string

It means that you are using an older haxelib version that is not compatible with haxe 5.0.0-preview.1.

You can either update it:

Or remove it (and use the version shipped with Haxe):

If that doesn't work, try running the command with --global.
