Starting with 3.1, Emailizr only supports Twig 3.9

[dpfaffenbauer]

@solverat doesn't this break Pimcore features like glossary or custom block rendering?

[solverat]

@dpfaffenbauer not sure, what you mean. It's basically the same as before. We're just using yield instead of echo and the new CaptureNode instead of the ob_get_clean.

[dpfaffenbauer]

Pimcore itself doesn't work with twig 3.9. you require it and pimcore is conflicting it.

[solverat]

Ah, ok. Well, you can't install emailizr 3.1, as long pimcore doesn't support twig 3.9. But this conflict in pimcore is just temporarily.

For now:

• emailizr 3.0 => with conflict
• emailizr 3.1 => twig 3.9 support

[dpfaffenbauer]

@solverat you know how temporary stuff is in Pimcore right ;) Just wanted to make sure you know that emailizr is incompatible with Pimcore now. I don't see the point in this quick change when Pimcore is not ready yet.
