This minor release fixes a bug in the authorizations/tokens pruning logic used in the EF 6/EF Core stores and improves the development encryption/signing certificates mechanism to prevent an exception from being thrown when multiple certificates with the same name are generated concurrently by different applications.
To ensure OpenIddict-based applications don't use a version impacted by CVE-2021-26701, this release also updates the OpenIddict.Abstractions package to explicitly reference the latest System.Text.Encodings.Web patched version. For more information, read dotnet/announcements#178.
