+# Change log
+
+## 0.2.0 (2022-07-15)
+
+- Python versions 3.7 and earlier are no longer supported because Kafkit is adopting the `annotations` import from `__future__` and native support for `importlib.metadata`.
+  Kafkit is explicitly tested with Python 3.8, 3.9, and 3.10.
+
+- We've added a `kafkit.ssl` module to help connect to Kafka brokers over TLS.
+  The associated documentation includes a tutorial for working with the SSL certificates generated in a Kafka cluster managed by [Strimzi](https://strimzi.io).
+
+- The brand-new `kafkit.registry.manager.RecordNameSchemaManager` provides a streamlined workflow for serializing Avro messages using Avro schemas that are maintained in your app's codebase.
+  The manager handles schema registration for you.
+  To serialize a message, you simply need to provide the data and the name of the schema.
+
+- A new `kafkit.registry.sansio.CompatibilityType` Enum helps you write use valid Schema Registry compatibility types.
+
+- We've significantly improved Kafkit's packaging and infrastructure:
+
+  - Migrate packaging metadata from `setup.py` to `pyproject.toml` (Kafkit continues to be a setuptools-based project).
+  - Tox now runs tasks like tests, in conjunction with the existing Pytest set up.
+  - Pre-commit hooks lint and format the code base.
+  - Code style is now handled by Black (and in the documentation with blacken-docs).
+  - **Full support for type annotations!** `tox -e typing` validates Kafkit's type annotations with Mypy.
+  - We've migrated from Travis CI to GitHub Actions.
+
+- The documentation now includes a development guide.
+
+## 0.1.1 (2019-02-13)
+
+Several fixes:
+
+- `RegistryApi.put` was doing a `PATCH` behind the scenes. That's fixed now.
+- The `RegistryApi.put`, `patch`, and `delete` methods weren't returning data. That's fixed now as well.
+- All of the RegistryApi's low-level HTTP methods have more thorough unit testing now to avoid these issues in the future.
+
+## 0.1.0 (2019-01-30)
+
+Initial release of Kafkit!
+
+This release includes the `kafkit.registry` package with a working [Confluent Schema Registry](https://docs.confluent.io/current/schema-registry/docs/index.html) API client implemented with a sans I/O design.
+There are two client implementations.
+One is designed for [aiohttp](https://aiohttp.readthedocs.io/en/stable/) users (`kafkit.registry.aiohttp.RegistryClient`), and the other is for I/O-free unit testing (`kafkit.registry.sansio.MockRegistryApi`).
+The clients include schema caches so they can be used as both local stores of schemas, in addition to accessors for remote schemas.
+The release also includes a suite of Avro message serializers and deserializers that integrate with [Confluent Schema Registry](https://docs.confluent.io/current/schema-registry/docs/index.html) and the Confluent Wire Format (`kafkit.registry.serializer`).
