Code.org ships daily deploys as Sprite Lab migrates to the Lab2 framework

edtechsprite-labcontinuous-deploymentplatform-migrationk12-codinglab2
◆Current state
Code.org operates on a continuous deployment cadence, shipping multiple named releases per week. The most user-visible ongoing work is migrating Sprite Lab to the Lab2 platform — improving image handling, workspace loading, game mechanics, and performance. The unified backpack (cross-lab asset storage) is gaining user-facing controls as it matures.
◆Where it's heading
The Lab2 migration is consolidating Code.org's scattered coding environments onto a single architecture, with Sprite Lab furthest along. Once Sprite Lab completes the migration, other labs are likely to follow. The analytics infrastructure is also modernizing — switching from direct Redshift access to the Data API and adding new SQL views for workshop data.
◆Prediction
Sprite Lab's Lab2 migration will reach feature parity with the original implementation within the next 4–6 weeks, at which point a second lab will likely begin migration. Unified backpack will continue gaining cross-lab features as Lab2 becomes the default surface.

    v2026-09-15.0: Infrastructure cleanup and style bundling

    Infrastructure cleanup: scss-lint removed, remaining Sprockets-managed styles moved into app bundles, and the Rails cache gets a dedicated directory. Routine housekeeping with no user-visible effect.

    v2026-09-10.0: Sprite Lab Lab2 image handling improvements

    Sprite Lab Lab2 adds small thumbnail previews for image lists and decodes only the images the active scene uses, reducing memory overhead. Incremental Lab2 migration work with narrow user impact.

    v2026-09-08.0: Unified backpack adds filter and sort

    Unified backpack gains filter and sort options, giving students meaningful control over stored assets across labs. Fits the Lab2 migration arc: as more labs share the backpack, discoverability of stored items becomes a real UX problem this change begins to address.

    v2026-09-04.0: Analytics SQL view, Redshift Data API migration

    Analytics infrastructure work: a new SQL view provisions course offerings and PD workshop data for the analytics pipeline, and the ETL job switches from direct Redshift access to the Data API. No student or teacher-facing changes.
