Failed to push to Heroku: fails on Ruby version

When I push to Heroku I get the following error:

remote: Building source:
remote: 
remote: -----> Ruby app detected
remote: -----> Compiling Ruby/Rails
remote:        Your app was upgraded to bundler 1.13.6.
remote:        Previously you had a successful deploy with bundler 1.11.2.
remote:        
remote:        If you see problems related to the bundler version please refer to:
remote:        https://devcenter.heroku.com/articles/bundler-version
remote: -----> Using Ruby version: ruby-2.3.0

remote:        Old: ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]
remote:        New: ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]
remote:        Running: bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin -j4 --deployment
remote:        Your Ruby version is 2.3.0, but your Gemfile specified 2.3.1
remote:        Bundler Output: Your Ruby version is 2.3.0, but your Gemfile specified 2.3.1
remote:  !
remote:  !     Failed to install gems via Bundler.
remote:  !
remote:  !     Push rejected, failed to compile Ruby app.
remote: 
remote:  !     Push failed

It works locally. Locally, ruby -v returns ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]. rvm list rubies gives the following:

   ruby-1.9.3-p551 [ x86_64 ]
   ruby-2.1.5 [ x86_64 ]
   ruby-2.2.1 [ x86_64 ]
=* ruby-2.3.1 [ x86_64 ]

How to solve this issue? Is Heroku not yet accepting Ruby 2.3.1? I could of course switch back locally to version 2.3.0 but I would expect this not to be necessary?

You can run gem install bundler, then bundle install to update your Ruby version in Gemfile.lock so that the app can use correct Ruby version specified in Gemfile.
