The release notes are inclusive. System requirements and all updates are noted in the subsequent component child pages. See the Product Announcements and Alerts page for all released versions, along with release dates, across product versions.
Types of Release Notes
In addition to the enhancements, upgrade notes, resolved issues, known issues, and End of Life (EOL) notices, the release notes include certain limited-availability releases, as well as security and support fixes.
Controller and Agent Releases
The versioning of AppDynamics language agents is done independently of each other and the Controller. Starting in release 4.5.0, agents are backward-compatible with any 4.4.1 or higher Controller, so you can simply download and install the latest version of the agent without having to keep track of your agent versions. See Agent and Controller Compatibility for more information.
