[0.37.0] - 2026-07-30

Adopter summary
Who must act Anyone pinning etlantic==0.36.x or plugins with <0.37
Breaking Dependency floor becomes etlantic>=0.37.0,<0.38 (stable-foundation line). Remaining demoted root aliases and DataContractModel removed
Upgrade pip install 'etlantic==0.37.0' and matching plugins / medallantic==0.37.0. See Migration 0.36 → 0.37
Rollback Re-pin 0.36.0 minors together; re-validate
Security Compatibility fixtures and reports remain secret-free; production allowlist pins fail closed; security verification matrix ships with automated checks

Added

  • Stable-foundation acceptance suite evidence for items 1–21
    (tests/stable_foundation/ + scripts/check_stable_foundation.py)
  • Security verification matrix with owner + automated check per control
    (docs/02_FOUNDATIONS/SECURITY_VERIFICATION_MATRIX.md,
    scripts/check_security_matrix.py)
  • Diagnostic-code stability tiers inventory
    (docs/10_REFERENCE/DIAGNOSTIC_STABILITY_TIERS.md,
    scripts/check_diagnostic_stability.py)
  • Release baseline / burn-in fixtures for v0_37 under
    tests/fixtures/releases/ and tests/fixtures/burn_in/
  • What's New / Migration / Exit Gate / Findings documentation for 0.37

Changed

  • Official package versions align at 0.37.0; plugins require
    etlantic>=0.37.0,<0.38 (external echo reference pin
    etlantic>=0.37,<0.38)
  • Supported security release line is 0.37.x
  • etlantic.testing graduates from preview freeze to stable
    application-pipeline testing foundation
  • Public surface / protocol freeze inventories align to the 0.37 reference
    envelope; first-party packages declare etlantic>=0.37.0,<0.38
  • etlantic.scheduler/1 remains stable MVP; etlantic.quality/1 remains
    provisional; DataFusion remains experimental; Arrow stays Gate A only
  • PyPI Beta classifier retained on core and first-party packages

Removed

  • Remaining demoted root facade aliases (_DEMOTED_ALIASES empty;
    _REMOVED_0_37 raises with migration guidance)
  • DataContractModel root / contracts compatibility alias; use
    etlantic.Data / ContractModel

Fixed

  • Root removal regressions covered by
    tests/unit/test_root_removals_0_37.py and testing-foundation suites
  • Docs / release-facts / artifact verification contract pointed at v0.37.0
    (expected after tag; digests filled at publish)

Upgrade notes

  • Pin core and matching plugins / medallantic together at ==0.37.0
  • Replace demoted root imports and any DataContractModel usage before
    upgrade
  • Plugin authors: raise the floor to etlantic>=0.37.0,<0.38 and re-run
    public conformance
  • Prefer graduated public etlantic.testing for application pipeline cases
