Is version 4 stable?

Hi, firstly thanks to Backendless developers and supporters.I’ve developed an android app with backendless:3.0.25.

I want to know that if version 4 is stable.At the same time, if I continue to develop with version 3x, version 3 will be supported until when?
Thanks…

Hi Grul,

Version 4 is currently in beta, which means it goes through additional testing and some errors may occur.

Version 3 will be available after 4 is released out of beta, however, apps on the free plan would need to migrate to version 4. Apps in 3.x on the paid plans will not need to migrate.

Regards,
Mark
