This release demonstrates four major items.
First, how boundary values for all settings (including the mutable and immutable items) may be managed in the configuration files and database both during the normal operation and API calls and also during the uni/multi-database migration operations.
Second, how the settings mutation transaction lifetime can be extended in order to cover the use case objects instantiation.
Third, how multiple RESTful API versions may be served together when they have small differences and it is not desired to just keep the latest version and remove the old versions.
Fourth, how the standard log/slog package may be used, both during the normal logging in the adapters and use cases layers and also by the Gin framework itself.
