Version 4.0.0, released 2022-06-08

This is the first version of this package to depend on GAX v4.

There are some breaking changes, both in GAX v4 and in the generated code. The changes that aren't specific to any given API are described in the Google Cloud documentation. We don't anticipate any changes to most customer code, but please file a GitHub issue if you run into problems.

The most important change in this release is the use of the Grpc.Net.Client package for gRPC communication, instead of Grpc.Core. When using .NET Core 3.1 or .NET 5.0+ this should lead to a smaller installation footprint and greater compatibility (e.g. with Apple M1 chips). Any significant change in a core component comes with the risk of incompatibility, however - so again, please let us know if you encounter any issues.

• Correct broken ConversationModelEvaluation resource pattern (commit 52734a8)

This is a breaking change in terms of resource names, which weren't correctly defined in the API before. We will release a new GA version once we're satisfied that no further breaking changes will be required.
