+### Added
+
+- Full async/await support with new `amazon_creatorsapi.aio` subpackage ([#143](https://github.com/sergioteula/python-amazon-paapi/pull/143))
+- `AsyncAmazonCreatorsApi` class for non-blocking API interactions
+- Async HTTP client with `httpx` integration for connection pooling
+- `AuthenticationError` exception for improved OAuth2 error handling
+- Optional `[async]` installation extra: `pip install python-amazon-paapi[async]`
+- Comprehensive async test suite with integration tests
+- Documentation for async API usage in README and usage guide
+- `make docs` command in Makefile for building documentation
+
+### Changed
+
+- GitHub Actions workflow now installs async dependencies for complete test coverage
+- Test coverage threshold lowered from 99% to 98% to accommodate async tests
+- Additional Ruff linting rules for test files (ARG002, S101, S105, S106, SIM117)

+### Async Support
+
+For async/await applications, use the async version of the API with `httpx`:
+
+```bash
+pip install python-amazon-paapi[async] --upgrade
+```
+
+The async API provides the same methods as the synchronous version, but they must be called with `await`:
+
+```python
+from amazon_creatorsapi.aio import AsyncAmazonCreatorsApi
+from amazon_creatorsapi import Country
+
+# Use as async context manager (recommended for connection pooling)
+async with AsyncAmazonCreatorsApi(
+    credential_id="your_credential_id",
+    credential_secret="your_credential_secret",
+    version="2.2",
+    tag="your-affiliate-tag",
+    country=Country.US,
+) as api:
+    items = await api.get_items(["B01N5IB20Q"])
+    results = await api.search_items(keywords="laptop")
+    variations = await api.get_variations("B01N5IB20Q")
+    nodes = await api.get_browse_nodes(["667049031"])
+
+# Or use without context manager (creates new connection per request)
+api = AsyncAmazonCreatorsApi(ID, SECRET, VERSION, TAG, COUNTRY)
+items = await api.get_items(["B01N5IB20Q"])
+```
+
+> **Note:** All synchronous methods and parameters work identically in async mode. Use `async with` for better performance when making multiple API calls.
