MonthlyPreparationService is no longer needed when releases are performed using the API
Services::MonthlyPreparationService is used to create stable
branches of all components we release every month. The API release code we are
working on as part of &236 (closed)
handles this on a per component basis. This means this service is redundant when
we start using the API code.
When the API code is proven to be stable and ready for permanent use, we should phase out this service class and any corresponding chatops commands that trigger it.
