A new configuration to flush the idle database connections after a specified period. Defaults to 300 seconds. This change will ensure that you don't have idle database connections hanging around in your connection pool.
This change ensures that forked children don't send quit/shutdown/goodbye messages to the server on connections that belonged to their parent. It will prevent the connection leakage that might happen when connections are not closed when workers are forked from parent process.
When form_with was introduced the auto generation of ids was disabled. Labels don't play well in such cases when the inputs don't have ids and it also made it harder to test the forms. This change enables the auto-generation of ids by default and allows to disable it using a config.
ActiveRecord::RecordNotFoundError accepts arguments such as primary_key,model_name and the arguments besides the error message. This change makes all the calls to this error uniform by passing these arguments wherever they were missing.
