# Eventstore fixes - `event.Position` used float64 before which can lead to [precision loss](https://github.com/golang/go/issues/47300). The type got replaced by [a type without precision loss](https://github.com/jackc/pgx-shopspring-decimal) - the handler reported the wrong error if the current state was updated and therefore took longer to retry failed events. # Mirror fixes - max age of auth requests can be configured to speed up copying data from `auth.auth_requests` table. Auth requests last updated before the set age will be ignored. Default is 1 month - notification projections are skipped because notifications should be sent by the source system. The projections are set to the latest position - ensure that mirror can be executed multiple times --------- Co-authored-by: Livio Spring <livio.a@gmail.com>
