Hi Sylius Team,

I am attempting to update my project dependencies, but I am running into a version conflict related to psr/http-message.

The newer versions of league/oauth2-server-bundle (and other modern libraries) now require psr/http-message: ^2.0. However, it appears that the current version of sylius/sylius constraints this package to ^1.0.

Context on Release Dates:

psr/http-message v2.0 was released in August 2023 (introducing strict types).

Since v1.0 is nearly a decade old, many ecosystem packages are migrating to v2.0 exclusively, which prevents Sylius projects from using updated versions of those libraries.

Question: Is there a plan to bump support to ^1.0 || ^2.0 in the core Sylius packages to allow for this upgrade?
