Release 2.1 checklist

[sosukesuzuki]

• prepare
  • Complete milestone items
  • Run on other projects to check for regressions
  • Write release notes
    • use scripts/draft-blog-post.js to generate a blog post draft (a file named YYYY-MM-DD-version.md in website/blog) from changelog_unreleased
    • replace "Prettier stable" and "Prettier master" in code examples with the actual versions (example)
    • prs-merged-since (readme) may be useful
    • PR: Add 2.1 blog post #8932
• publish
  • Run release script
• postpublish
  • Merge release notes
  • Wait for release notes to deploy
  • Tweet from @PrettierCode account via TweetDeck
  • Close milestone
  • Send schema PR generated by scripts/generate-schema.js to SchemaStore if we added a new option.
    • Update schema for .prettierrc for Prettier 2.1 SchemaStore/schemastore#1213
  • Update the release checklist with possible changes

Then monitor Twitter/GitHub for any immediate issues 😄

@evilebottnawi Let's discuss about what we should include next release, here! from: #8861 (comment).

What is status of typescript@4, because I think we will need to do release for this too?

Ideally I think we need to support TS 4.0 in next release with default typescript parser(typescript-estree). But I'm not sure when typescript-estree will support all of features TS 4.0. We have already supported TS 4.0 features via Babel so I don't think there is a big problem if we release it as it is.

/cc @JamesHenry friendly ping, any ETA?

[fisker]

so I don't think there is a big problem if we release it as it is.

I agree, and once it's done, we can still support it with a path release.

@evilebottnawi I've been hands off for personal reasons in the recent past (will be returning in the next month or so), so @bradzacher would be much better placed to give an update

typescript-eslint/typescript-eslint#2260

Just needs support for Labelled Tuple Elements.
I haven't had a chance to do it as I've been working on our own v4 release ^[1].
There wasn't any great rush for it because nobody had really pushed for it yet, and TS4.0 is still in beta (I think the RC is coming this week).

If someone wants to go add it in ASAP, then it can be released as soon as Monday.
It should be pretty simple to setup because it's just standard Identifier parsing.

I can probably take a look on the weekend?

---

[1] side note that our 4.0 might be a bit of a pain for you guys because we're supporting the new optional chaining syntax.

[fisker]

We probably won't ship new version with beta version of TS4.0, so I don't think we need typescript-eslint support it before stable TS4.0 relase.

[sosukesuzuki]

Can you write a script for this step?

Okay, I'll try to do.

[bradzacher]

Support for labelled tuple elements: typescript-eslint/typescript-eslint#2378

[sosukesuzuki]

@bradzacher Thank you, could you tell me when will the PR be released?

[bradzacher]

Tomorrow morning!

[sosukesuzuki]

Great! We'll use next ts-eslint/parser and support labelled tuple elements on Prettier 2.1!
#8982 (comment)

[fisker]

Regression on build script cause by #8639

Before, require('parse-*') is "Dynamic Require", now it's not, this will slow down prettier, I'll try to find a way or revert that PR.
