✅ Release Checklist

Note for whomever is owning the release: please capture notes as comments in this issue for anything you noticed that could be improved for future releases. There is a Post Release step below for incorporating changes back into the RELEASE_ISSUE_TEMPLATE, and this is easier done by collecting notes from along the way rather than just thinking about it at the end.

First steps:

• Fork a new branch (release/vX.Y.Z) from master and make any further release related changes to this branch. If any "non-trivial" changes get added to the release, uncheck all the checkboxes and return to this stage.
• Bump the version in build/version.go in the master branch to vX.Y.(Z+1)-dev (bump from feature release) or vX.(Y+1).0-dev (bump from mandatory release). Run make gen and make docsgen-cli before committing changes

Prepping an RC:

• version string in build/version.go has been updated (in the release/vX.Y.Z branch)
• run make gen && make docsgen-cli
• Generate changelog using the script at scripts/mkreleaselog
• Add contents of generated text to lotus/CHANGELOG.md in addition to other details
• tag commit with vX.Y.Z-rcN
• cut a pre-release here

Testing an RC:

• Stage 0 - Automated Testing

  • Automated Testing
    • CI: Ensure that all tests are passing.
    • Testground tests

• Stage 1 - Internal Testing

  • Binaries
    • Ensure the RC release has downloadable binaries
  • Upgrade our testnet infra
    • Wait 24 hours, confirm nodes stay in sync
  • Upgrade our mainnet infra
  • Subset of development full archival nodes
  • Subset of bootstrappers (1 per region)
  • Confirm nodes stay in sync
  • Metrics report
    • Block validation time
    • Memory / CPU usage
    • Number of goroutines
    • IPLD block read latency
    • Bandwidth usage
  • If anything has worsened significantly, investigate + fix
  • Confirm the following work (some combination of Testground / Calibnet / Mainnet / beta users)
    • Seal a sector
    • make a deal
    • Submit a PoSt
    • (optional) let a sector go faulty, and see it be recovered

• Stage 2 - Community Testing

  • Test with SPX fellows
  • Work on documentations for new features, configuration changes and so on.

• Stage 3 - Community Prod Testing

  • Update the CHANGELOG.md to the state that can be used as release note.
  • Invite the wider community through (link to the release issue)

• Stage 4 - Stable Release

  • Final preparation
    • Verify that version string in version.go has been updated.
    • Verify that codegen is up to date (make gen && make docsgen-cli)
    • Ensure that CHANGELOG.md is up to date
    • Merge release-vX.Y.Z into the releases branch.
    • Tag this merge commit (on the releases branch) with vX.Y.Z
    • Cut the release here.

• Post-Release

  • Merge the releases branch back into master, ignoring the changes to version.go (keep the -dev version from master). Do NOT delete the releases branch when doing so!
  • Update RELEASE_ISSUE_TEMPLATE.md with any improvements determined from this latest release iteration.
  • Create an issue using RELEASE_ISSUE_TEMPLATE.md for the next release.
