Hi folks

#39 changed some composer defined constraints to make them semver compatible.
But some of those versions chosen are pretty old.

I'm working with Magento2 which has a dependency on allure-framework/allure-php-api. And they recently upgraded from version 1.1.4 to 1.1.5 (of which the only difference is #39).
Now to my surprise I noticed some packages being downgraded and some older packages which we no longer need getting installed, for example:

- Downgrading jms/serializer (1.14.0 => 0.16.0)
- Downgrading symfony/http-foundation (v4.3.3 => v2.8.50)
- Installing ircmaxell/password-compat (v1.0.4)
- Installing symfony/polyfill-php54 (v1.12.0)
- Installing symfony/polyfill-php55 (v1.12.0)
- Updating allure-framework/allure-php-api (1.1.4 => 1.1.5)

Magento2 supports PHP 7.1 to 7.3 and most of these libraries are more related with PHP 5.x so we don't really need these.

Therefore I would like ask if some dependencies in this package could changed to include more modern versions.

Suggestion:

        "jms/serializer": "^0.16 || ^1.0",
        "symfony/http-foundation": "^2.0 || ^3.0 || ^4.0"

Would there be any interest in this?

Thanks!
