+* [BREAKING CHANGE: Proto3 standard compatibility improvements](https://github.com/awakesecurity/proto3-suite/pull/143)
+  * This is a breaking change due to adding a new `DotProtoMessageOption`
+    constructor to `DotProtoMessagePart`, which requires updating any
+    exhaustive pattern matches
+* [BREAKING CHANGE: Don't capitalize first character of prefixed service method names](https://github.com/awakesecurity/proto3-suite/pull/171)
+  * This is a breaking change because the generated Haskell code will have
+    slightly different field names for service methods
+* [BREAKING CHANGE: Remove `Optional` from Protobuf AST](https://github.com/awakesecurity/proto3-suite/pull/165)
+  * This is a technically breaking change because we no longer support the
+    `optional` keyword, but this wasn't supported by proto3 anyway
+* [Support GHC 9.0.2](https://github.com/awakesecurity/proto3-suite/pull/176)
+* [Fix dashes in Haskell module names](https://github.com/awakesecurity/proto3-suite/pull/173)
+  * This prevents the code generator from generating invalid Haskell module
+    names with dashes in them
+* [Add `Message` instance for wrapped types](https://github.com/awakesecurity/proto3-suite/pull/162)
+  * This adds `Message` instances for several scalar Haskell types that
+    correspond to the standard `*Wrapper` protobuf types
+* [Use Swagger schema `format` to distinguish wrapper types from primitives](https://github.com/awakesecurity/proto3-suite/pull/167)
+* [Update codegen to add the `serverMaxMetadataSize` field to generated `ServiceOptions`](https://github.com/awakesecurity/proto3-suite/pull/181)
+* [Fix module renaming in `compile-proto-file`](https://github.com/awakesecurity/proto3-suite/pull/183)

-version:             0.4.2
-synopsis:            A low level library for writing out data in the Protocol Buffers wire format
+version:             0.5.0
+synopsis:            A higher-level API to the proto3-wire library
+description:
+  This library provides a higher-level API to <https://github.com/awakesecurity/proto3-wire the `proto3-wire` library>
+  that supports:
+  .
+  - Type classes for encoding and decoding messages, and instances for all wire
+    formats identified in the specification
+  - A higher-level approach to encoding and decoding, based on `GHC.Generics`
+  - A way of creating `.proto` files from Haskell types.
+  .
+  See <https://hackage.haskell.org/package/proto3-suite/docs/Proto3-Suite-Tutorial.html the `Proto3.Suite.Tutorial` module>
+  for more details.
