@nicolas-grekas I reverted the milestone. We cannot introduce a new deprecation in 5.0.x

About the migration cost ... I would never change therender() method becauseeverybody uses it ... butrenderView() is much less popular (in my experience and from what I've seen out there: render() is used more than 100 times more often that renderView() ... but this is only my experience).

Seems about right. Not exactly a factor of 100 but here some numbers from my biggest Symfony 4.4 work project:

$ grep -r --include *Controller.php  'this->render(' src/ vendor/ | wc -l180$ grep -r --include *Controller.php  'this->renderView(' src/ vendor/ | wc -l14

Another point. MVC division: Model, view, controller. Most programmers associate with such an approach that the controller generates a view, not a template.

Thank you@javiereguiluz.

Actually, that's a hard BC break. What if one already has arenderTemplate() method in their controllers? ... well, it happens that EasyAdmin does this, and it is broken now. Shall we revert?

Sure, let's revert if it needs more thoughts.

@fabpot I hadn't thought about that ... but then, we'll never be able to add any new method to AbstractController ... because someone may have already defined it 🤔

@javiereguiluz That's correct :(

A possible solution would be to deprecate defining customrenderTemplate() methods and adding it in Symfony 6.0:

publicfunctionrenderView(...){if (method_exists($this,'renderTemplate')) {        @trigger_deprecation('            You define a custom renderTemplate() method in your controllers,            but Symfony will add that method in Symfony 6.0, so you should            rename your method.');    }// ...}

But then we could only deprecaterenderView() in Symfony 6 and remove it in Symfony 7 (to be released in November 2023). Maybe the simplest solution is to keep therenderView() and that's it.
