Preface

These release notes describe prerequisites for installation, known issues and improvements to the software, changes and deprecated functionality, and other important information.

ForgeRock Identity Platform™ is the only offering for access management, identity management, user-managed access, directory services, and an identity gateway, designed and built as a single, unified platform.

The platform includes the following components that extend what is available in open source projects to provide fully featured, enterprise-ready software:

  • ForgeRock Access Management (AM)

  • ForgeRock Identity Management (IDM)

  • ForgeRock Directory Services (DS)

  • ForgeRock Identity Gateway (IG)

Chapter 1. What's New in This Release

The Identity Message Broker is a publish-subscribe broker service that secures and hardens the sending and receiving of messages between an MQTT client and the cloud in Internet of Things (IoT) systems.

The Identity Message Broker provides the following features, which are a subset of the MQTT specification:

  • Quality of Service (QoS) level 0

  • Ping, publish, and subscribe methods

  • Secure MQTT (MQTTS) for the MQTT server connection

  • Authentication of MQTT clients through certificates and keys

ForgeRock Access Management acts as an authorization server, to authenticate MQTT clients through OpenID Connect tokens.

This chapter describes new features, improvements, and fixes in the Identity Message Broker.

1.1. New Features

This is the first release of Identity Message Broker.

1.2. Security Advisories

ForgeRock issues security advisories in collaboration with our customers and the open source community to address any security vulnerabilities transparently and rapidly. ForgeRock's security advisory policy governs the process on how security issues are submitted, received, and evaluated as well as the timeline for the issuance of security advisories and patches.

For more information, see ForgeRock's Security Policy.

    AM is used to authenticate MQTT clients, authenticate the Identity Message Broker, and provide a policy decision point. For information, see the Access Management documentation.

Chapter 4. Fixes, Limitations, and Known Issues

This chapter describes the status of fixes, limitations, and known issues at this release.

4.1. Key Fixes

This is the first release. No key fixes are attributed to this release.

4.2. Limitations

The Identity Message Broker supports a subset of the MQTT specification. For information about the features provided by IMB, see Chapter 1, "What's New in This Release". This release includes the following limitations:

Quality of Service (QoS) Level 0 Only

Each MQTT publish is sent with QoS 0, in which the sender tries with best effort to send a message once, and relies on the reliability of TCP. A message is never resent.

Even if the client requests to subscribe with a QoS 1 or QoS 2, a QoS 0 is provided. A client cannot recuperate a missed message.

Non-persistent sessions

Information for a client is not saved by the IMB when the session closes. For example, a client that is connected and subscribed to topics must resubscribe if it disconnects and reconnects.

Last will and testament

Clients cannot currently specify a last will message to be sent when they disconnect ungracefully.

4.3. Known Issues

No important known issues are attributed to this release.
