Symfony CMF packages

$ composer show --latest 'symfony-cmf/*'

Subject

Composer won't install the package because it needs a lower version

Steps to reproduce

Trying to require and install the package while using Symfony 5

Expected results

The package is installed and tested

Actual results

$ composer require symfony-cmf/seo-bundle
Using version ^2.1 for symfony-cmf/seo-bundle
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Restricting packages listed in "symfony/symfony" to "5.0.*"
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for symfony-cmf/seo-bundle ^2.1 -> satisfiable by symfony-cmf/seo-bundle[2.1.0].
    - symfony-cmf/seo-bundle 2.1.0 requires symfony/framework-bundle ^2.8 || ^3.3 || ^4.0 -> no matching package found.
Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.
 - It's a private package and you forgot to add a custom repository to find it

Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

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