This release focuses on improving the new OpenIddict.Client.WebIntegration package by introducing built-in Microsoft.Extensions.Options support to configure the provider settings and allowing opt-in HTTP decompression for the providers that require it.
With Keycloak, LinkedIn, PayPal and StackExchange being added in preview4, OpenIddict.Client.WebIntegration now offers 10 provider integrations. To simplify registering the ECDSA signing key required for client authentication, the Apple provider now exposes options.SetSigningKey() overloads accepting PEM-encoded keys (the format used by Apple).
As part of this release, the OpenIddict.Client.SystemNetHttp and OpenIddict.Validation.SystemNetHttp packages were also updated to allow configuring a ProductInformation property containing the name and version of the application optionally sent to the remote server as part of the User-Agent header, which can be useful when dealing with providers that require specifying a user agent (e.g Reddit).
