A big release. The mobile app catches up with five weeks of UX work, the macro sandbox goes live in production, and a long list of platform improvements ships alongside.

Mobile app (1.20)

Mobile jumps from 1.14.3 to 1.20.0; there is a lot here.

  • Per-measurement upload progress: the queued-measurements view shows live upload progress per item (#1437).

  • ESP32-C3 USB Serial/JTAG support for devices using that controller (OJD-1475).

  • Smarter questions-only flow: inline comments and flags, a preview/review step before submission, and a clear auto-advance banner (OJD-1435).

  • Bulk delete for synced measurements in a single tap (#1264).

  • Proper cancel on abort: sends the cancel command so the device returns to a known state (#1229).

  • Expo SDK 55 / RN 0.83 upgrade: fixes the React 19.2.4 crash and sets up over-the-air updates (#1292).

Macros & data

  • Macro sandbox is live: macros run in a sandboxed Lambda with the full 28-helper Python wrapper, routed end to end through backend, data, and mobile (#1053-1057, #1312, #1382).

  • Data repair framework: targeted, predicate-gated repairs for production data, with a guard against malformed PAM set arrays (#1375, #1384, #1402).

  • Protocol testing tool: a web-side tool to test protocols before publishing (#1157).

CMS & email

  • CMS-driven transactional email: bodies render from CMS rich text instead of being hardcoded (#1261, #1352).

  • Video in articles: a new ArticleVideo component for the rich-text editor (#1370).

Reliability, security & operations

  • Disaster recovery: backup and restore in place for eu-west-1 (#1152).

  • Vulnerability scanning: AWS Inspector v2 and Trivy scan CI/CD and runtime images (#1225).

  • Beta branding removed from the platform (#1185).

  • Monitoring: a PostgreSQL datasource and a user-registration dashboard (#1299, #1346).
