Some VERY exciting news!

Can’t wait till it’s finally marked as stable 
Congrats!
Should REALLY upgrade my CakePHP 2.x app…
This is super brilliant!
Congratulations to entire Cake team for the effort in achieving this milestone!
Will test out Alpha and report as much as I can!
Kudos to the team! 
Congratulations to entire team. It’s really a great effort by them.
TL;DR: Is there an anticipated timeline for stable release?
I’m 90% complete on a CakePHP 3.8 project and am trying to decide if I should migrate then release, or release then migrate. I understand that the alpha->beta->release process is highly fluid, but I was wondering if the team has a general goal in mind that I could consider in my own migration/release decision?
So glad to see PHP extensions in the view and the layouts now.
@calteran Stick with 3.8. When the time comes you should be able to upgrade to 4.0 relatively easily by following the migration guide.
Thanks for the update.
