 ## [Unreleased]
-- Placeholder for upcoming changes.
 
-## [1.0.0] - 2025-08-04
+_Promoted to `[0.1.0]` when the first release tag is cut._
+
 ### Added
-- Initial release of SlurmCostManager.
 
+- **Core billing engine** — real-time cost calculation from SlurmDB (MySQL/MariaDB).
+  Per-account, per-user, per-job cost breakdown. CPU-hour and GPU-hour tracking with
+  configurable rates. Historical rate support (`rates.json` with timestamped entries).
+  Configurable billing rules: failed job exclusion, short job exclusion, partition
+  discounts.
+
+- **SU bank / allocation management** — prepaid and postpaid allocation modes.
+  Annual/quarterly/monthly/custom allocation periods. Budget tracking with alert
+  thresholds at 80%, 90%, and 100%. Carryover rules. Admin dashboard view of all
+  account balances.
+
+- **Balance enforcement — Lua job_submit plugin** — real-time job rejection at
+  submission via `job_submit.lua`. `ENABLE_ENFORCEMENT` flag for audit-only mode.
+  User-visible error messages include remaining balance. Alternative:
+  `balance_enforcer.py --sync` for sites that cannot use Lua.
+
+- **PDF invoice generation** — ReportLab-based PDF with institution branding.
+  Line items include per-job breakdown, rates, and totals. Invoice lifecycle:
+  Draft → Sent → Viewed → Paid. Sequential invoice numbering. Bulk generation
+  by account.
+
+- **Credit memos** — refund support with linked credit memos. Adjustments
+  reflected in the invoice ledger.
+
+- **Role-based access control** — four roles: Admin, PI, Member, Finance.
+  PI auto-detection from Slurm account coordinators. Role-based UI with tabs and
+  actions gated by role.
+
+- **Setup wizard** — three-step first-run wizard: institution profile, billing
+  rates, DB connection test. Guides new admins through initial configuration without
+  editing JSON directly.
+
+- **RPM and DEB packaging** — `make rpm` / `make deb` produce installable packages.
+  RPM tested on Rocky Linux 9; DEB for Ubuntu/Debian. Packages handle config
+  directory creation and Cockpit restart in `%post` / `postinst`.
+
+- **Billing rules engine** — admin-configurable rule-based charge/no-charge
+  decisions. Admin-editable via UI with no config file editing required. Closed
+  operator set (no eval/exec security risk).
+
+- **Reports and CSV export** — monthly/quarterly/annual billing summaries.
+  RFC 4180 compliant CSV export. Journal entry CSV for ERP import (generic, not
+  Oracle-specific).
+
+- **Docker Compose test environment** — `test/vm/` and `docker-compose.yml` for
+  local development against a real MariaDB fixture. CI `db-integration` job
+  validates `slurmdb.py` against live MariaDB.
+
+- **CI pipeline** — GitHub Actions: lint, unit tests, MariaDB integration tests,
+  packaging dry-run. Five jobs: `lint`, `test`, `db-integration`, `package`,
+  `security-scan`.

+## Versioning
+
+SlurmLedger follows pre-1.0 [Semantic Versioning](https://semver.org/):
+
+- **Minor bumps** (`0.1.0` → `0.2.0`) may include breaking changes. Breaking changes
+  are called out under `### Breaking` in `CHANGELOG.md` and in the release notes.
+- **Patch bumps** (`0.1.0` → `0.1.1`) must be backwards-compatible bug fixes only.
+  No breaking changes, no new config keys required.
+- **Config-format breaks**: when a minor bump changes the format of `/etc/slurmledger/*.json`,
+  a migration script runs automatically in the `%post` section of the RPM and the `postinst`
+  section of the DEB. You should never need to hand-edit JSON to upgrade across a minor version.
+- **No deprecation period required pre-1.0.** Features may be removed without a deprecation
+  cycle before `v1.0.0`. After `v1.0.0`, full semver deprecation discipline applies.
+
+`v1.0.0` is cut when at least one production deployment at a real HPC center has been live
+for 30+ days without site-reported correctness issues in the billing engine. Until then,
+`0.x` versions are honest first-public-release signals, not feature-incomplete indicators.

 ## Config Schema Changes
 
-### v1.1.0 (Sprint 5-6)
-- `rates.json`: Added `allocations`, `billing_rules`, `billing_defaults` sections
-- `institution.json`: Added `roles`, `bankInfo`, `paymentTerms`, `paymentTermsDays`
-- NEW: `financial_config.json` — financial integration settings (was in institution.json)
-- NEW: `invoices.json` — invoice ledger (auto-created)
-
-### v1.0.0 (Initial)
-- `rates.json`: `defaultRate`, `defaultGpuRate`, `overrides`, `historicalRates`, `historicalGpuRates`
-- `institution.json`: Institution profile only
+### v0.1.0 (Initial public release)
+- `rates.json`: `defaultRate`, `defaultGpuRate`, `overrides`, `historicalRates`, `historicalGpuRates`,
+  `allocations`, `billing_rules`, `billing_defaults`
+- `institution.json`: `roles`, `bankInfo`, `paymentTerms`, `paymentTermsDays`
+- `financial_config.json`: financial integration settings (separate from institution.json)
+- `invoices.json`: invoice ledger (auto-created on first run)
 
 ## Migration Guide
-Existing `rates.json` files from v1.0.0 continue to work — new fields default gracefully.
-If you had `financialIntegration` in `institution.json`, move it to `financial_config.json`.
+
+No migrations required for v0.1.0 — this is the initial release.
+
+Future minor-version upgrades (`0.1.0` → `0.2.0`) may include config-format breaking changes.
+When they do, a migration script will run automatically in the `%post` section of the RPM
+and the `postinst` section of the DEB. You should never need to hand-edit JSON to upgrade
+across a minor pre-1.0 version. See `CHANGELOG.md` for any `### Breaking` entries before
+upgrading.
