clarkwinkelmann Hello Clark, I've encountered this strange message when I tried to install this extension on my beta 10 :
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Installation request for kilowhat/flarum-ext-mailing ^0.1.2 -> satisfiable by kilowhat/flarum-ext-mailing[0.1.2].
- kilowhat/flarum-ext-mailing 0.1.2 requires flarum/core >=0.1.0-beta.8 <0.1.0-beta.11 -> satisfiable by flarum/core[v0.1.0-beta.10, v0.1.0-beta.8, v0.1.0-beta.8.1, v0.1.0-beta.8.2, v0.1.0-beta.9] but these conflict with your requirements or minimum-stability.
Installation failed, deleting ./composer.json.
Did you understand what happens ?
