Cutting a Deno release

Pre-flight checklist

• An up to date stable Rust toolchain
• A binary version of deno available (hopefully built from main) that is going to be available throughout any local building you might do.
• Forks and local clones of denoland/deno, denoland/deno_std, denoland/dotland and denoland/deno_docker
• Ensure that external dependencies are up-to date in denoland/deno (e.g. rusty_v8, serde_v8, deno_doc, deno_lint).
• Ownership access on crates.io for the 19 (🙀) crates that you will be publishing. (Don't worry too much though as the main script publishing 18 of the crates allows recovery)
• Lot's of ☕

During this process main branch (or any other branch that you're creating release from) should be frozen and no commits should land until the release is cut.

Updating deno_std

1. Checkout a branch for releasing std (e.g. release_#.#.#).

2. Open a PR on the deno_std repo that bumps the version in version.ts and updates Releases.md

3. Before merging the PR, make sure that all tests pass when run using binary produced from bumping crates (point 3. from below).

4. Create a tag with the version number (without v prefix).

Updating the main repo

1. Checkout a branch for releasing crate dependencies (e.g. deps_#.#.#).

2. Run ./tools/release/01_bump_dependency_crate_versions.ts to increase the minor versions of all crates in the bench_util, core, ext, and runtime directories.

3. Commit these changes with a commit message like chore: bump crate version for #.#.# and create a PR for this change.

4. Make sure CI pipeline passes (DO NOT merge yet).

5. Run ./tools/release/02_publish_dependency_crates.ts to publish these bumped crates to crates.io

   Make sure that cargo is logged on with a user that has permissions to publish those crates.

   If there are any problems when you publish, that require you to change the code, then after applying the fixes they should be committed and pushed to the PR.

6. Once all crates are published merge the PR.

7. Update your main branch and checkout another branch (e.g. release_#.#.#).

8. Run ./tools/release/03_bump_cli_version.ts to bump the CLI version.

9. If you are doing a patch release, answer y to the Increment patch? prompt.

10. Use the output of the above command to update Releases.md

11. Update link in cli/compat/mod.rs with the released version of deno_std and do a search through the tests to find std urls that need to be updated.

12. Create a PR for these changes.

13. Make sure CI pipeline passes.

14. Publish cli crate to crates.io

15. Merge the PR.

16. Create a tag with the version number (with v prefix).

17. Wait for CI pipeline on the created tag branch to pass.

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

18. Upload Apple M1 build to the release draft & to dl.deno.land.

19. Publish the release on Github

20. Update the Deno version on the website by updating https://github.com/denoland/dotland/blob/main/versions.json.

21. Push a new tag to manual. The tag must match the CLI tag; you don't need to create dedicated commit for that purpose, it's enough to tag the latest commit in that repo.

22. 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.

Updating deno_docker

1. Open a PR on the deno_docker repo that bumps the Deno version in all Dockerfiles, the README and the example Dockerfile
2. Create a tag with the version number (without v prefix).
