# Publishing Guide

When publishing a new version of MetaMask, we follow this procedure:

## Preparation

We try to ensure certain criteria are met before deploying:

- Deploy early in the week, to give time for emergency responses to unforeseen bugs.
- Deploy early in the day, for the same reason.
- Make sure at least one member of the support team is "on duty" to watch for new user issues coming through the support system.
- Roll out incrementally when possible, to a small number of users first, and gradually to more users.

## Incrementing Version & Changelog

Version can be automatically incremented [using our bump script](./bumping-version.md).

npm run version:bump $BUMP_TYPE` where `$BUMP_TYPE` is one of `major`, `minor`, or `patch`.

## Preparing for Sensitive Changes

In the case that a new release has sensitive changes that cannot be fully verified prior to publication, please follow the [sensitive release protocol](./sensitive-release.md).

## Building

While we develop on the main `develop` branch, our production version is maintained on the `master` branch.

With each pull request, the @MetaMaskBot will comment with a build of that new pull request, so after bumping the version on `develop`, open a pull request against `master`, and once the pull request is reviewed and merged, you can download those builds for publication.
