Checklist for making a release:

 - [ ] Check that all "nextrelease" issues and pull requests are merged to ``develop``.
 - [ ] Create a commit in ``develop`` that updates the ``Changelog`` to include a release date (run the tests locally to update the bug list).
 - [ ] Create a pull request and wait for the tests, merge it.
 - [ ] Create a pull request from ``develop`` to ``release``, wait for the tests, then merge it.
 - [ ] Make a final check that there are no platform-dependency issues in the ``solc-test-bytecode`` repository.
 - [ ] Wait for the tests for the commit on ``release``, create a release in Github, creating the tag.
 - [ ] Thank voluntary contributors in the Github release page (use ``git shortlog -s -n -e origin/release..origin/develop``).
 - [ ] Wait for the CI runs on the tag itself (they should push artefacts onto the Github release page).
 - [ ] Run ``scripts/release_ppa.sh release`` to create the PPA release (you need the relevant openssl key).
 - [ ] Check that the Docker release was pushed to Docker Hub (this still seems to have problems).
 - [ ] Update the homebrew realease in https://github.com/ethereum/homebrew-ethereum/blob/master/solidity.rb (version and hash)
 - [ ] Make a release of ``solc-js``: Increment the version number, create a pull request for that, merge it after tests succeeded.
 - [ ] Run ``npm publish`` in the updated ``solc-js`` repository.
 - [ ] Create a commit to increase the version number on ``develop`` in ``CMakeLists.txt`` and add a new skeleton changelog entry.
 - [ ] Merge ``release`` back into ``develop``.
 - [ ] Announce on Twitter and Reddit.
 - [ ] Lean back, wait for bug reports and repeat from step 1 :)
