# Updating bazelbuild/platforms

WARNING: These are what worked last time. Reality might be different. 

## Step 1: Make the release

- Pick a new version number
- Update version.bzl
- Run distro/makerel.sh
- Go to the [Releases](https://github.com/bazelbuild/platforms/releases) page
- Draft a new release
  - Name the release with a version number
  - Use the version number as the title
  - Copy the description that makerel.sh produced to the description field.
  - upload the generated tar file

- use https://github.com/bazelbuild/continuous-integration/blob/HEAD/mirror/mirror.sh to mirror the file

## Step 2: Update Bazel

- Edit `distdir_deps.bzl`
- Merge the PR
