Release Activities

Daniel Rosenwasser edited this page May 17, 2022 · 29 revisions

This is the list of release activities needed for every TypeScript release. Additional activities are also needed if a new syntax is introduced or a new compiler option gets added.

The primary people managing a release should oversee these tasks along with the overall release process.

Release Candidate Activities

tslib

  • Add all tslib updates
  • Review next version number

@definitelytyped/header-parser and retag

Once main's version is updated, the @definitelytyped packages must be aware of the nightly's new version so that nightly versions of ATA continue to work. ATA relies on tsX.Y tags on @types/* packages.

  • Update @definitelytyped/typescript-versions to support the next version, and publish a new release.
    • in other words, if we're releasing TypeScript 3.9, the header parser needs to support 4.0.

Release Activities

Release

  • Tag release branch
  • Update AUTHORS.md for the release (script)
  • Draft and publish new release
  • Close milestone corresponding to the release

Project Health

  • Review perf dashboard to identify regressions
  • Review fuzzer-discovered crashes (and ensure these have been running)
  • Review NewErrors breaking change issues (and ensure these have been running)
