OT-2 External release assets
Live inventory of OT-2 app and robot OS artifacts published to S3/CloudFront. Showing the 5 most recent versions per manifest. Generated 2026-07-20 15:09:55 UTC.
Build job to URL map
OT-2 assets are uploaded by GitHub Actions in opentrons-ot2 (app) and buildroot (robot OS). Each successful run writes versioned artifacts under predictable S3 prefixes, then updates the channel manifests below.
| Component | Workflow | S3 prefix | Manifest | Per-build layout |
|---|---|---|---|---|
| App (external) | opentrons-ot2/.github/workflows/app-test-build-deploy.yaml | s3://ot2.builds.opentrons.com/app/ | releases.json, alpha*.yml | Opentrons-OT2-v<ver>-<platform>-b<build>.* |
| Robot OS (external) | buildroot/.github/workflows/build.yml | s3://ot2.builds.opentrons.com/ot2-br/ | ot2-br/releases.json | ot2-br/<github.run_id>/ot2-fullimage.zip |
See the channel section below for robot vs app manifest authority. OT-2 robots read ot2-br/releases.json for on-robot updates. External app URLs in releases.json use https://ot2.builds.opentrons.com/app/ after feat/ot2-calendar-semver-build (edge still writes ot2.opentrons.com).
External channel
Robot OS: releases.json is the source of truth for on-robot updates.
Flex robots on 9.1.1+ read the productionV2 key; older entries remain under
production.
Desktop app: channel YAML files (latest.yml, latest-mac.yml,
latest-linux.yml, and prerelease YAMLs) are authoritative; electron-updater reads those
directly. App releases.json is not the app updater source of truth: a CloudFront edge
function parses the latest stable semver from production and routes latest* requests to
matching stable build artifacts. The tables below are still useful for humans and release validation.
Updater YAML overwrite: beta desktop publishes overwrite alpha.yml as
well as beta.yml; alpha publishes update alpha.yml only. Tag push order can
differ from publish order. When both channels need builds, publish beta before alpha so
alpha.yml ends on the alpha build.
