# remix.ethereum.org update

This is not strictly speaking a release. Updating the remix site is done through the Travis build:

 - git co -b remix_live origin/remix_live
 - git reset --hard -master-commit-hash-
 - git push -f origin remix_live

 CircleCI will build automatically and remix.ethereum.org will be updated

# remix-alpha.ethereum.org update

remix-alpha.ethereum.org is automatically updated every time commits are pushed to master
