Calendar Versioning Syntax
Rather than version numbers using the Semantic Versioning syntax of x.y.z (i.e., 4.5.18), the calendar-based format will reflect the date of release into the version number. The following syntax would be used instead: yy.m.x.
For example, if a Java Agent is released in March of 2020, its version will begin with 20.3.0. Likewise, the first release of September will be 20.9.0, while the first release of October will be 20.10.0. If another version of an agent is released in the same month, the last number of the version would be incremented. For example, if a second version of the Java Agent were released in March 2020, the second version would be 20.3.1.

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 later Controller, so you can download and install the latest version of the agent without having to keep track of your agent versions. See Agent and Controller Compatibility.
