 ## 2.0.0a2
 
-### Various fixes & improvements
+## New Features
+
+- Additional integrations will now be activated automatically if the SDK detects the respective package is installed: Ariadne, ARQ, asyncpg, Chalice, clickhouse-driver, GQL, Graphene, huey, Loguru, PyMongo, Quart, Starlite, Strawberry.
+
+## Changed
+
+- The Pyramid integration will not capture errors that might happen in `authenticated_userid()` in a custom `AuthenticationPolicy` class.
+- The method `need_code_loation` of the `MetricsAggregator` was renamed to `need_code_location`.
+- The `BackgroundWorker` thread used to process events was renamed from `raven-sentry.BackgroundWorker` to `sentry-sdk.BackgroundWorker`.
+- The `reraise` function was moved from `sentry_sdk._compat` to `sentry_sdk.utils`.
+- The `_ScopeManager` was moved from `sentry_sdk.hub` to `sentry_sdk.scope`.
+- Moved the contents of `tracing_utils_py3.py` to `tracing_utils.py`. The `start_child_span_decorator` is now in `sentry_sdk.tracing_utils`.
+- The actual implementation of `get_current_span` was moved to `sentry_sdk.tracing_utils`. `sentry_sdk.get_current_span` is still accessible as part of the top-level API.
+- `sentry_sdk.tracing_utils.get_current_span()` does now take a `scope` instead of a `hub` as parameter.
+- `sentry_sdk.utils._get_contextvars` does not return a tuple with three values, but a tuple with two values. The `copy_context` was removed.
+- If you create a transaction manually and later mutate the transaction in a `configure_scope` block this does not work anymore. Here is a recipe on how to change your code to make it work:
+    Your existing implementation:
+    ```python
+    transaction = sentry_sdk.transaction(...)
+
+    # later in the code execution:
+
+    with sentry_sdk.configure_scope() as scope:
+        scope.set_transaction_name("new-transaction-name")
+    ```
+
+    needs to be changed to this:
+    ```python
+    transaction = sentry_sdk.transaction(...)
+
+    # later in the code execution:

+## Removed
+
+- Removed support for Python 2 and Python 3.5. The SDK now requires at least Python 3.6.
+- Removed support for Celery 3.\*.
+- Removed support for Django 1.8, 1.9, 1.10.
+- Removed support for Flask 0.\*.
+- Removed `last_event_id()` top level API. The last event ID is still returned by `capture_event()`, `capture_exception()` and `capture_message()` but the top level API `sentry_sdk.last_event_id()` has been removed.
+- Removed support for sending events to the `/store` endpoint. Everything is now sent to the `/envelope` endpoint. If you're on SaaS you don't have to worry about this, but if you're running Sentry yourself you'll need version `20.6.0` or higher of self-hosted Sentry.
+- The deprecated `with_locals` configuration option was removed. Use `include_local_variables` instead. See https://docs.sentry.io/platforms/python/configuration/options/#include-local-variables.
+- The deprecated `request_bodies` configuration option was removed. Use `max_request_body_size`. See https://docs.sentry.io/platforms/python/configuration/options/#max-request-body-size.
+- Removed support for `user.segment`. It was also removed from the trace header as well as from the dynamic sampling context.
+- Removed support for the `install` method for custom integrations. Please use `setup_once` instead.
+- Removed `sentry_sdk.tracing.Span.new_span`. Use `sentry_sdk.tracing.Span.start_child` instead.
+- Removed `sentry_sdk.tracing.Transaction.new_span`. Use `sentry_sdk.tracing.Transaction.start_child` instead.
+- Removed `sentry_sdk.utils.Auth.store_api_url`.
+- `sentry_sdk.utils.Auth.get_api_url`'s now accepts a `sentry_sdk.consts.EndpointType` enum instead of a string as its only parameter. We recommend omitting this argument when calling the function, since the parameter's default value is the only possible `sentry_sdk.consts.EndpointType` value. The parameter exists for future compatibility.
+- Removed `tracing_utils_py2.py`. The `start_child_span_decorator` is now in `sentry_sdk.tracing_utils`.
+- Removed the `sentry_sdk.profiler.Scheduler.stop_profiling` method. Any calls to this method can simply be removed, since this was a no-op method.
+
+## Deprecated
+
+- `profiler_mode` and `profiles_sample_rate` have been deprecated as `_experiments` options. Use them as top level options instead:
+  ```python
+  sentry_sdk.init(
+      ...,
+      profiler_mode="thread",
+      profiles_sample_rate=1.0,
+  )
+  ```
+- Deprecated `sentry_sdk.transport.Transport.capture_event`. Please use `sentry_sdk.transport.Transport.capture_envelope`, instead.
+- Passing a function to `sentry_sdk.init`'s `transport` keyword argument has been deprecated. If you wish to provide a custom transport, please pass a `sentry_sdk.transport.Transport` instance or a subclass.
+- The parameter `propagate_hub` in `ThreadingIntegration()` was deprecated and renamed to `propagate_scope`.
