Sinatra dependancy broken

[kgathi2]

Bundled Sinatra a few days ago and it worked. But now not working

# Gemfile
gem 'sinatra', require: false, github: 'sinatra'

# Console error
Bundler could not find compatible versions for gem "rack-protection":
  In Gemfile:
    sinatra was resolved to 2.0.0.pre.alpha, which depends on
      rack-protection (~> 2.0)

Could not find gem 'rack-protection (~> 2.0)', which is required by gem 'sinatra', in any of the sources.

Had to require last stable commit

gem 'sinatra', require: false, github: 'sinatra', ref: 'e7ef8e234fd36e389ec7e23d562de488fde7abff'

Waiting for stable release. Can't use gem sidekiq-web for now due to an Issue
