HTTP2::Client.new throws ArgumentError (wrong number of arguments (given 1, expected 0)) on Ruby 3.0

I'm getting this:

irb(main):001:0> require 'http/2'
=> true
irb(main):002:0> conn = HTTP2::Client.new
Traceback (most recent call last):

This is my environment

Any ideas?

It seems related to the way Ruby 3 handles named parameters. The issue seems fixed on master with #156

@igrigorik - any idea when this fix will get released as a new gem version? The AWS SDK for Ruby currently breaks with the latest gem version of http-2 on Ruby 3.0, but I've confirmed all our tests pass when using the latest from master.

New release is live, this should be resolved. Please reopen if you run into any other issues!
