These release notes cover multiple versions of IG software, starting with version 5.5. They are designed to make it easier to upgrade, especially when you are skipping releases.
ForgeRock supports and maintains versions according to the ForgeRock Product Support Lifecycle Policy | IG and Agents. Some older IG versions have reached Product End of Life (EOL). If you are still running an EOL version, upgrade as soon as possible to an actively maintained version.
IG integrates web applications, APIs, and microservices with the ForgeRock Identity Platform. Based on reverse proxy architecture, IG enforces security and access control in conjunction with Access Management modules.
ForgeRock® Identity Platform serves as the basis for our simple and comprehensive Identity and Access Management solution. We help our customers deepen their relationships with their customers, and improve the productivity and connectivity of their employees and partners. For more information about ForgeRock and about the platform, see https://www.forgerock.com.
The ForgeRock® Common REST API works across the platform to provide common ways to access web resources and collections of resources.
