Haxe development builds

Road to Haxe 5.0

Dear Community,

We are currently working towards Haxe 5.0 which, as a major version, will include a number of breaking change.

To ease the migration from Haxe 4, we introduced -D haxe-next in Haxe 4.3. This define activates a number of warnings about things that will not work anymore in Haxe 5.0.

Roadmap

Main features that are currently being worked on:

• Haxe Coroutines (#12168)
• IDE integration improvements

• Release 5.0 Milestone
