Hey the gem is not compatible with Ruby 3.1

To make it work with a new Rails project I had to add gem "matrix", "~> 0.4" to my Gemfile. Maybe this should be added as a dependency.

It is added in the master. It will be in the next release.

@NordGus Duplicate, see #1235 and #1195, therefore closing the issue.

[joemasilotti]

Would it be possible to cut a release that includes this update? I can't deploy Prawn to Heroku running Ruby 3.1 or 3.2 without pointing directly to master.

[pointlessone]

@joemasilotti Eventually. Just out of curiosity, how do you imagine a release will be different from master?

[joemasilotti]

I feel safer knowing I can lock into a version release instead of pointing to a branch. And if/when things change in the future, I can assess how to upgrade based on semantic versioning.

@joemasilotti Thank you.
