--- id: index title: Introduction --- > This feature was introduced in _Unleash v3.11.0_. Unleash Addons allows you to extend Unleash with new functionality. Currently, addons allow you to listen to changes in Unleash and trigger updates in other systems, typical via a WebHook. Currently Unleash support the following Addons out of the box: - [Webhook](./webhook) - A generic way to post messages from Unleash to third party services. - [Slack](./slack) - Allows Unleash to post updates to Slack. - [Microsoft Teams](./teams) - Allows Unleash to post updates to Microsoft Teams. - [Datadog](./datadog) -allows Unleash to post Updates to Datadog when a feature toggle is updated. In future releases we plan to support community built addons. ### Notes {#notes} When updating or creating a new addon configuration it can take up to one minute before Unleash picks up the new config on all instances due to caching.
