# DentalCare v0.9.2.0 Release Notes

## Main correction

Update status now has one source of truth: installed version plus the exact current-release migration ledger. Optional documentation and health/readiness diagnostics no longer create a false update button.

## Release-state changes

- Machine release metadata moved to `config/release_manifest.json`.
- Removing handbooks or release notes no longer changes update status.
- Completed checkpoints are normalized from the immutable migration plan and ledger.
- Current-release checksum verification retains the official v0.9.1.2 compatibility repair.
- The v0.9.1.4 checkpoint progress repair is carried forward.

## Documentation

Fresh client-facing installation, handbook, privacy, license, and release-note files are included under `docs/client/`. They may be removed from a deployed server without affecting application update status.

## Data safety

The migration is non-destructive. It does not delete or rewrite patient, clinical, appointment, payment, staffing, inventory, document, or audit records.
