Incompatibility with Symfony 4.4

[xaviermarchegay]

I have a near standard Sylius installation and I ran 'composer update' after the install.
When I try to install the Refund plugin, I am told that the package is not compatible with Symfony 4.4.

composer require sylius/refund-plugin
Using version ^0.9.1 for sylius/refund-plugin
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for sylius/refund-plugin ^0.9.1 -> satisfiable by sylius/refund-plugin[v0.9.1].
    - Conclusion: remove symfony/framework-bundle v4.4.0
    - Conclusion: don't install symfony/framework-bundle v4.4.0
    - sylius/refund-plugin v0.9.1 requires symfony/messenger ~4.3.0 -> satisfiable by symfony/messenger[v4.3.0, v4.3.1, v4.3.2, v4.3.3, v4.3.4, v4.3.5, v4.3.6, v4.3.7, v4.3.8].
    - symfony/messenger v4.3.0 conflicts with symfony/framework-bundle[v4.4.0].
    - symfony/messenger v4.3.1 conflicts with symfony/framework-bundle[v4.4.0].
    - symfony/messenger v4.3.2 conflicts with symfony/framework-bundle[v4.4.0].
    - symfony/messenger v4.3.3 conflicts with symfony/framework-bundle[v4.4.0].
    - symfony/messenger v4.3.4 conflicts with symfony/framework-bundle[v4.4.0].
    - symfony/messenger v4.3.5 conflicts with symfony/framework-bundle[v4.4.0].
    - symfony/messenger v4.3.6 conflicts with symfony/framework-bundle[v4.4.0].
    - symfony/messenger v4.3.7 conflicts with symfony/framework-bundle[v4.4.0].
    - symfony/messenger v4.3.8 conflicts with symfony/framework-bundle[v4.4.0].
    - Installation request for symfony/framework-bundle (locked at v4.4.0) -> satisfiable by symfony/framework-bundle[v4.4.0].

Installation failed, reverting ./composer.json to its original content.
