Learning API – 1.2.3

Bug Fixes

  • certificates: retry a failed certificate with a backoff and park it, so it never stalls the rest (f21b867)
  • courses: a draft with a final assessment stays saveable and publishable (3e8501e)
  • events: record an event as processed only after its effects; retry a failed one (28d139d)
  • deps: clear the October RustSec advisories (b5d5917)
  • deps: move aws-sdk-s3 to 1.144.0 for lru 0.18 (a1956f4)
  • deps: move to sea-orm 2.0 and sqlx 0.9, which takes rsa out of the lockfile (7189307)
  • evidence: check the enrolment, then the image header, before decoding; decode with limits (34e9f55)
  • release: release from staging (rc) and develop (beta), as the other services do (9235cb2)
