Staging, and a preview for every pull request

Try a change somewhere safe before your visitors see it.

What's new

• Staging, and up to 5 other environments, from the environment switcher at the top of a project. Each is a full copy with its own apps, empty databases, variables and a free address hidden from search engines.

• Production is marked in red, and every screen says which environment you're in.

• Promote: send the build you tested on staging to production, byte for byte, without building again. Roll back as usual.

• Shared variables, set once for every environment, with an app's own variable winning.

• A password on an environment's address, so only the people you choose can open it.

• Previews of pull requests: each pull request on your GitHub repository gets its own preview, built again on each push, with its address posted on the pull request. A pull request from someone else's fork waits until you choose Approve and build.

• Never production's secrets: staging and previews start without production's variables and data, so a test can't send real emails or take real payments.
