# WSO2 API Manager 4.0.0 Released!

The WSO2 API Manager team is pleased to announce the release of version 4.0.0 of the Open Source API Manager.

The WSO2 API Manager is a fully open source full lifecycle API Management product that can be deployed on-prem,
available on SaaS, deployed on a private cloud or deployed in a hybrid model. It is comprised of the following
components that provides all of its functionality.

- API Designer and Publisher: Allows API creators to design, implement and document APIs and
  allows API product managers to manage the lifecycle of APIs and create API products by using one or more APIs.
- Developer Portal: A portal for onboarding application creators. It allows application creators to discover,
  subscribe, test and consume APIs through their applications.
- API Gateway: Allows access to APIs/services by routing application traffic to the relevant endpoints.
  The API Gateway is the component that enforces security, rate-limiting and transformations on API requests while
  feeding valuable information of these requests to API Analytics.
- Key Manager: The security token service of the API Manager which is responsible for handling everything
  related to authentication and authorization of API requests. It supports a wide variety of security protocols such
  as OAuth2.0/OIDC, Basic Auth, API Key, SAML based single-sign-on.
- Traffic Manager: Controls the traffic flow of the API gateway. This is used to apply request quotas on APIs
  for monetization, access control or security related matters. In addition to configuring the available policies, users
  can deploy their own policies on the traffic manager which will control the rate of traffic on the API gateways.
- API Analytics: Monitors all traffic that’s routed through the API gateways to analyse usage patterns,
  SLA violations, consumer behaviours, to provide business insights and so on.
