+# modern-di-aiogram 2.2.0 — adopt the modern-di integration kit
+
+Maintenance release. **No public API change** — `FromDI`, `inject` (both
+`modern_di_aiogram` and `modern_di_aiogram.dialog`), `setup_di`,
+`fetch_di_container`, and the two connection providers keep their signatures
+and behavior. Swaps this package's hand-rolled connection-scope lifecycle
+and marker resolution for the shared primitives in
+[`modern_di.integrations`](https://github.com/modern-python/modern-di/blob/main/architecture/integration-kit.md),
+shipped in
+[modern-di 2.28.0](https://github.com/modern-python/modern-di/releases/tag/2.28.0).
+Twelfth of 13 planned adapter conversions across the `modern-di` ecosystem
+(after
+[`modern-di-starlette` 2.2.0](https://github.com/modern-python/modern-di-starlette/releases/tag/2.2.0),

+and
+[`modern-di-taskiq` 2.1.0](https://github.com/modern-python/modern-di-taskiq/releases/tag/2.1.0)).
+
+aiogram is the kit's documented **Layer-1 outlier**: its per-update child
+container's context is a hand-written multi-provider merge with a hardcoded
+scope (`{Update: event, TelegramObject: event.event}`, two aiogram types
+from one event) that no single-provider `bind()` can derive — so that
+literal is kept, and **no `bind`/`classify_connection` is introduced**. Only
+the container lifecycle and the marker/resolution seam adopt the kit.
+
+## Internal refactors
+
+- **`_DiMiddleware` now opens/closes the per-update child through
+  `Container`'s own `async with`** (replacing the manual `try`/`finally:
+  await child.close_async()`). The multi-provider `context={...}` literal and
+  both `ContextProvider` registrations are unchanged.
+- **`_FromDI` is gone; `FromDI = integrations.from_di`.** `_parse_inject_params`
+  is deleted; `inject` composes `integrations.parse_markers`/
+  `integrations.resolve_markers`.
+- **The `__modern_di_injected__` double-wrap guard is now
+  `integrations.is_injected`/`integrations.mark_injected`** (same underlying
+  attribute — used in `inject` and `auto_inject`'s `_inject_router`).
+- **`modern_di_aiogram.dialog`** (the aiogram-dialog `inject`, which shares
+  the marker) converts its `parse_markers`/`resolve_markers` usage in the
+  same change.
+- The `inject` signature-rewrite machinery (the deliberate non-use of
+  `functools.wraps`, driven by aiogram's `__wrapped__` unwrapping) and
+  `dialog.py`'s `_container_from_call` call-shape lookup are aiogram-specific
+  glue, kept exactly as-is.
+- Dead imports removed (`dataclasses`, the `T_co` TypeVar).
+- `architecture/dependency-injection.md` promoted to describe the new
+  internals.
+
+## Packaging
+
+- Bumps the `modern-di` floor to `>=2.28,<3`.
+
+## Downstream
+
+No action needed — the public API (`FromDI`, `inject`, `setup_di`,
+`fetch_di_container`, `aiogram_update_provider`, `aiogram_event_provider`,
+and `modern_di_aiogram.dialog.inject`) is unchanged. Upgrading only requires
+`modern-di>=2.28.0`.
+
+## Internals
+
+- 100% line coverage; `ruff`, `ty` clean across Python 3.10–3.14. Tests use
+  a fake-token `Bot` and `aiogram_dialog.test_tools` (no external service).
+- Built via `subagent-driven-development`: 5 planned tasks, each with an
+  independent spec+quality review; a whole-branch review before merge that
+  verified no `bind`/`classify_connection` was introduced, the `async with`
+  preserves the old close semantics on both the normal and handler-error
+  paths, and the double-wrap guard round-trips through the same
+  `__modern_di_injected__` attribute.
