New Features

An after_no_matching_login configuration method has been added to run code after a login attempt where the login didn’t match an active account.
A uses_instance_variables configuration method has been added for Rodauth configurations to specify custom instance variables used inside the configuration blocks.

Other Improvements

The active_sessions feature will now clear other active sessions when multifactor authentication is initially added to an account. In this case, other active sessions will only have been single factor authenticated, but marked as fully authenticated. Disabling such sessions improves security, because otherwise the sessions would be treated as fully authenticated (which they were at the time of authentication), when they would not be treated as fully authenticated after the addition of multifactor authentication.
On Ruby 3.2+, if YJIT is available, a shape-friendly approach is used for Rodauth::Auth instances, where all internal instance variables are set to nil during initialize.
Requiring rodauth now works without previously requiring rack or rack/version.

External features should update their code to set the Auth instance variables the feature sets via the new uses_instance_variables feature method.
The auth_cached_method feature method was implemented using a non-shape-friendly approach, and is now soft deprecated. External features are are recommended to switch to the new cached_auth_method feature method, which offers a shape-friendly approach, but instance variables that can legitimately have a nil value will require additional changes.
External features and configuration blocks that checked whether instance variables were defined will need to be updated, as when using a shape-friendly approach, the instance variables are set to nil during initialization. Instead of using defined? or instance_variable_defined?, .nil? can be used. Cases where nil can be a valid value for an instance variable may require additional adjustment.
The json_request? method in the json feature now returns true or false, when it previously returned an integer or nil.
