4.0.0

What's Changed

Thanks so much for all the effort you put into this release 🙌. We are continuing to align Testcontainers for .NET with other language implementations and working on improving the domain-specific language.

We have updated the IImage interface to follow the domain-specific language with the correct property names. The table below shows the changes. We tried to make the transition as smooth as possible, but be aware that relying on the Repository property might cause issues since it now resolves a different value than before. We have kept the old properties, marked them as obsolete, and provided guidance on how to migrate.

	Actual	Expected (New)
Registry	-	myregistryhost:5000
Repository	myregistryhost:5000/fedora	fedora/httpd
Name	httpd	-
Tag	version1.0	version1.0
Digest	-	sha256:37a3b014d320...
GetHostname()	myregistryhost:5000	myregistryhost:5000

Thank you to everyone whose contributions made this release possible.

What's Changed

⚠️ Breaking Changes

The UntilOperationIsSucceeded(Func<bool>, int, Action<IWaitStrategy>) wait strategy is obsolete. Instead of this wait strategy, use any other wait strategy that matches your use case and configure the retry behavior accordingly (wait strategy options).

Using reuse together with the container builder method WithName(string) will generate a new reuse hash the first time you use the configuration. The container name was not included in calculating the reuse hash previously.

What's Changed

⚠️ Breaking Changes

If you have overwritten the default logger previously (setting TestcontainersSettings.Logger), please be aware that each builder now offers a dedicated API to configure the actual logger. This has several advantages; among others, it integrates very nicely into xUnit.net's scoped loggers.

What's Changed

⚠️ Breaking Changes

The members of the container and image builder, WithImagePullPolicy and WithImageBuildPolicy, previously received a callback argument of type ImagesListResponse. We've now updated these callbacks, and they will receive an argument of type ImageInspectResponse. This change was implemented to offer more detailed information regarding the actual cached image.
