What's the best way to change one variable in .env file? Clone the Airbyte GitHub repo, change the variable and update Airbyte instance from a cloned repo? And do it again when the new version is rolled out?

I don’t know that it’s “the best way”, but in my local repository I created a branch and committed my changes to my local branch. When I want to upgrade I just rebase to the version I want to use:

$ git rebase v0.32.5-alpha

I’ve been using it for a couple months and it seems to work alright.
