    Dremio Cloud is not versioned publicly. The changelog is a dated stream grouped into
    "What's New" and "Improvements & Fixes", with each entry carrying its internal issue key
    (DX-#####, DPD-###) — an unusually good practice: a customer can quote the exact ticket back
    to support.
  enterprise: semver-major
  enterprise_note: >-

    ODBC and legacy JDBC drivers, and a dependencies page covering security fixes.
