+# faststream-outbox 0.10.4 — internal refactors + richer PyPI metadata, no behavior change
+
+**Patch release.** Every change to the installed package is an **internal refactor** —
+the runtime behaves identically to 0.10.3 (same producer, subscriber, lease/terminal-write,
+timer, DLQ, and validation behavior). The one user-visible change is **richer PyPI package
+metadata**. Drop-in upgrade.
+
+## Internal refactors (no behavior change)
+
+These deepen the codebase without changing any observable behavior; they exist to remove
+duplication and concentrate logic, verified by the unchanged test suite (and a new
+cross-adapter contract suite).
+
+- **Outbox rules de-duplicated between the real and fake clients.** The genuinely-shared
+  pure bits are now single-sourced — `_scheduling.py` (activate-args resolution +
+  validation, shared by the real and fake publish paths) and `_DLQ_PROJECTION` in
+  `schema.py` (one declarative outbox→DLQ column map both the real DLQ CTE and the fake
+  build from). The rules that must run server-side in Postgres (eligibility, lease cutoff,
+  retry timing) stay as two implementations but are now **co-verified** by a single
+  parametrized contract suite run against both the real client and the in-memory fake.
+  ([#109](https://github.com/modern-python/faststream-outbox/pull/109))
+- **Lease-lost telemetry has one home.** The byte-identical detect→log→emit block that the
+  terminal and retry flush paths each carried is consolidated into a single
+  `_emit_lease_lost(row, *, phase)` helper. ([#110](https://github.com/modern-python/faststream-outbox/pull/110))
+- **`OutboxSubscriberConfig` validates itself.** Subscriber-knob validation moved from the
+  factory into `OutboxSubscriberConfig.__post_init__`, so *every* construction path is
+  guarded, not just `@broker.subscriber`. Behavior is preserved exactly; warning
+  attribution (the warning points at your `@subscriber` call site) is now computed via a
+  manual stacklevel walk so it's robust across CPython 3.13/3.14 and the FastAPI-router
+  path. ([#111](https://github.com/modern-python/faststream-outbox/pull/111))
+
+## Packaging
+
+- **Richer PyPI metadata** — keywords, classifiers, and project URLs. Better
+  discoverability and project links on the PyPI page; no install-time or runtime effect.
+  ([#108](https://github.com/modern-python/faststream-outbox/pull/108))
+
+## Migration
+
+None. Drop-in upgrade from 0.10.x — no public-API change, no schema change, no config
+change. If you don't construct `OutboxSubscriberConfig` directly (the normal case), nothing
+about your code changes; if you *do*, it now validates on construction (rejecting the same
+impossible values the factory always rejected).
+
+## Touched surface
+
+- **Package code (internal only):** `faststream_outbox/_scheduling.py` (new),
+  `publisher/producer.py`, `broker.py`, `schema.py`, `client.py`, `testing.py`,
+  `subscriber/usecase.py`, `subscriber/config.py`, `subscriber/factory.py`.
+- **Packaging:** `pyproject.toml` (metadata only).
+- **Tests:** `tests/test_client_contract.py` (new, cross-adapter contract), plus updates
+  to `tests/test_unit.py`, `tests/test_fake.py`, `tests/test_integration.py`.
+- **Living docs:** `CLAUDE.md`, `architecture/dlq.md`, `architecture/test-broker.md`.
