v4.1.0
Since Graylog 4.1 ships with a built-in Slack integration with same ID slack-notification-v1
with this plugin. So I have decided to rename this plugin ID to graylog-plugin-slack-notification
You need to run the following command on Mongodb before install a new plugin in order to migrate current configuration to a new plugin version
graylog:PRIMARY> use graylog
graylog:PRIMARY> db.auth('graylog', 'your-graylog-mongodb-password');
graylog:PRIMARY> db.event_notifications.updateMany({"config.type":"slack-notification-v1"},{$set: { "config.type": "graylog-plugin-slack-notification"}})
