+## [1.73.0] - 2026-03-12
+
+### Added
+
+- Add end-to-end test for calibration database build pipeline.
+- Unified calibration pipeline with GPU-accelerated L1/L0 solver, target config YAML, and CLI package validator.
+  Per-state and per-county precomputation replacing per-clone Microsimulation (51 sims instead of 436).
+  Parallel state, county, and clone loop processing via ProcessPoolExecutor.
+  Block-level takeup re-randomization with deterministic seeded draws.
+  Hierarchical uprating with ACA PTC state-level CSV factors and CD reconciliation.
+  Modal remote runner with Volume support, CUDA OOM fixes, and checkpointing.
+  H5 builder that filters calibrated clone weights by CD subset, uses pre-assigned random census blocks from `geography.npz` to derive full sub-state geography, and produces self-contained local area datasets.
+  Staging validation script (validate_staging.py) with sim.calculate() comparison and sanity checks.
+
+### Changed
+
+- Geography assignment now prevents clone-to-CD collisions.
+  County-dependent vars (aca_ptc) selectively precomputed per county; other vars use state-only path.
+  Target config switched to finest-grain include mode (~18K targets).
+- Migrated from changelog_entry.yaml to towncrier fragments to eliminate merge conflicts.
+
+### Fixed
+
+- Cross-state cache pollution in matrix builder precomputation.
+  Takeup draw ordering mismatch between matrix builder and stacked builder.
+  At-large district geoid mismatch (7 districts had 0 estimates).
+
+
