• Fork this gist and follow the instructions there.

Pre-flight

During this process $BRANCH_NAME branch should be frozen and no commits should land until the release is finished.

• Ensure forks and local clones of:
  • denoland/deno,
  • denoland/dotcom,
  • denoland/deno_docker,
  • denoland/deno-docs
• Check https://deno.land/benchmarks?-100 and ensure there's no recent regressions.
• Write a message in company's #cli channel:

Deno v$VERSION is now getting released.

`denoland/deno` is now locked.

*DO NOT LAND ANY PRs*

Release checklist: <LINK TO THIS FORKED GIST GOES HERE>

Patch release preparation

If you are cutting a patch release: First you need to sync commits to the v$MINOR_VERSION branch in the deno repo.

To do that, you need to cherry-pick commits from the main branch to the v$MINOR_VERSION branch. If the branch doesn't exist yet, create one from the latest minor tag:

# checkout latest minor release
$ git checkout v$PAST_VERSION

# create a branch
$ git checkout v$MINOR_VERSION

# push the branch to the `denoland/deno` repository
$ git push upstream v$MINOR_VERSION

For patch releases we want to cherry-pick all commits that do not add features to the CLI. This generally means to filter out feat commits.

Check what was the last commit on v$MINOR_VERSION branch before the previous release and start cherry-picking newer commits from the main.

Once all relevant commits are cherry-picked, push the branch to the upstream and verify on GitHub that everything looks correct.

• ⛔ DO NOT create a v$VERSION-like branch! You are meant to cherry pick to the v$MINOR_VERSION branch. If you have accidentally created then v$VERSION branch then delete it as tagging the CLI will fail otherwise.

Updating deno

Phase 1: Bumping versions

• Go to the "version_bump" workflow in the CLI repo's actions: https://github.com/denoland/deno/actions/workflows/version_bump.yml

  1. Click on the "Run workflow" button.
  2. In the drop down, select the minor branch (v$MINOR_VERSION) if doing a patch release or the main branch if doing a minor release.
  3. For the kind of release, select either "patch", "minor", or "major".
  4. Run the workflow.

• Wait for the workflow to complete and for a pull request to be automatically opened. Review the pull request, make any necessary changes, and merge it.

  • ⛔ DO NOT create a release tag manually That will automatically happen.
  Failure Steps

  1. Checkout the branch the release is being made on.
  2. Manually run ./tools/release/01_bump_crate_versions.ts
     1. Ensure the crate versions were bumped correctly
     2. Ensure Releases.md was updated correctly
  3. Open a PR with the changes and continue with the steps below.

Phase 2: Publish

• Go to the "cargo_publish" workflow in the CLI repo's actions: https://github.com/denoland/deno/actions/workflows/cargo_publish.yml

  1. Run it on the same branch that you used before and wait for it to complete.
  Failure Steps

  1. The workflow was designed to be restartable. Try restarting it.
  2. If that doesn't work, then do the following:
     1. Checkout the v$MINOR_VERSION branch.
     2. If cargo publish hasn't completed then run ./tools/release/03_publish_crates.ts
        • Note that you will need access to crates.io so it might fail.
     3. If cargo publish succeeded and a release tag wasn't created, then manually create and push the v$VERSION tag on the v$MINOR_VERSION branch.

• This CI run create a tag which triggers a second CI run that publishes the GitHub draft release.

  The CI pipeline will create a release draft on GitHub (https://github.com/denoland/deno/releases).

• ⛔ Verify that:

  • There are 14 assets on the release draft.
  • There are 10 zip files for this version on dl.deno.land.

• Publish the release on Github

• Run https://github.com/denoland/dotcom/actions/workflows/update_version.yml to automatically open a PR.

  • Merge the PR.

• Run https://github.com/denoland/deno-docs/actions/workflows/update_versions.yml to automatically open a PR.

  • Merge the PR.

• For minor releases: make sure https://github.com/mdn/browser-compat-data has been updated to reflect Web API changes in this release. Usually done ahead of time by @lucacasonato.

• If you are cutting a patch release: a PR should have been automatically opened that forwards the release commit back to main. If so, merge it. If not and it failed, please manually create one.

Updating deno_docker

• Run the version bump workflow: https://github.com/denoland/deno_docker/actions/workflows/version_bump.yml
• This will open a PR. Review and merge it.
• Create a $VERSION tag (without v prefix).

Updating deno-lambda

• Run the version bump workflow: https://github.com/denoland/deno-lambda/actions/workflows/bump.yml
• This will open a PR. Review and merge it.
• Create a $VERSION tag (without v prefix).

All done!
