Epic released Unreal Engine 4 with $ 19 subscription sources

Most recently, I received a letter from Epic where it’s reported that they make it accessible to everyone.
Unreal Engine 4 by subscription for $ 19 per month for development for PC, Mac, iOS, and Android, with a payment condition of 5% of the amount of sales.
And most importantly, C ++ sources are available that will
spread via github (although you can also use the binary version).

Also promise:

• the ability to end a subscription at any time and continue to use the engine without updates
• support for Mac OS X and XCode (but they write that as long as it’s so far away from the ideal, like Android).
• built-in app store for selling content and extensions

The site has a warning that this is an early release that has not yet been finalized.
and that if you are looking for a product that is truly ready for commercial development, then this should be expected in about six months.
