+# Migration Guide

+## 3.0.0
+
+Reference: https://slack.dev/python-slack-sdk/v3-migration/index.html#from-slackclient-2-x
+
+### Use  ``AsyncWebClient`` for async options
+
+With v3 upgrade, `WebClient` no longer has `run_async` and `aiohttp` specific options. If you still need the option or other `aiohttp` specific options, use `LegacyWebClient` (slackclient v2 compatible) or `AsyncWebClient`
+
+
+### Include ``aiohttp`` in requirements
+
+`aiohttp` is no longer automatically resolved with `slack_sdk`(earlier `slackclient`). So, if working with `AsyncWebClient`, `AsyncWebhookClient`, and `LegacyWebClient`, it needs separate installation.

Review comment:
       ```suggestion
   ## 2.0.0
   
   We updated the support for `sentry_sdk` from ``>=2.0.0,<3.0.0`` to ``>=3.0.0,<4.0.0``. In most cases, this doesn't mean any breaking changes to the DAG files, but if you used this library directly then you have to make the changes. For details, see the `Migration Guide
   <https://slack.dev/python-slack-sdk/v3-migration/index.html#from-slackclient-2-x>`__ for Python Slack SDK.
   ```
   
   We should only focus on the changes that affect our project. In this case, there aren't too many breaking changes except that sometimes users may have conflicting dependencies.
