+# modern-di-taskiq 3.0.0 — modern-di 3.x
+
+Requires **modern-di >= 3, < 4**. **No public API change** — `FromDI`,
+`fetch_di_container`, `setup_di`, and `taskiq_message_provider` keep their
+signatures and behavior. The adapter already drove the explicit open/close
+container lifecycle (`async with` around the per-task child container, and
+`container.open()` / `await container.close_async()` on the root container
+via the `WORKER_STARTUP` / `WORKER_SHUTDOWN` event handlers), so no adapter
+code changed for
+[modern-di 3.0's mandatory-open lifecycle](https://modern-di.modern-python.org/migration/to-3.x/).
+
+## Packaging
+
+- **Bumped the `modern-di` dependency to `>=3,<4`.** Requires modern-di 3.x;
+  drops support for modern-di 2.x.
+
+## Downstream
+
+No action needed beyond raising your own `modern-di` floor to `>=3`. If your
+code builds child containers, open them with `with` / `async with` (or
+`open()`) before resolving — see the
+[modern-di 3.x migration guide](https://modern-di.modern-python.org/migration/to-3.x/).
+
+## Internals
+
+- 100% line coverage; `ruff`, `ty` clean.
