Installation broken in 4.0.0 RC 24

This extension fails in 4.0.0 RC 24:

Using version ^1.0 for bobdenotter/rss-extension
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Restricting packages listed in "symfony/symfony" to "^4.4"
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for bobdenotter/rss-extension ^1.0 -> satisfiable by bobdenotter/rss-extension[1.0.0, 1.0.1].
    - Installation request for twig/twig (locked at v3.0.3) -> satisfiable by twig/twig[v3.0.3].
    - twig/twig v2.12.0 conflicts with cocur/slugify[v4.0.0].
    - twig/twig v2.12.0 conflicts with cocur/slugify[v4.0.0].
    - twig/twig v2.12.0 conflicts with cocur/slugify[v4.0.0].
    - Conclusion: install twig/twig v2.12.0
    - Installation request for cocur/slugify (locked at v4.0.0) -> satisfiable by cocur/slugify[v4.0.0].

I've tagged a new release that allows for Twig 3, but there's another issue.. I'm working on that: bolt/core#1524
