AppDynamics maintains and supports every software version for one calendar year after the next major software release is generally available. For example, support and maintenance of the 20.3 release will continue for 12 months after the 20.4 release.

See Product Announcements and Alerts.

For specific maintenance and support terms, refer to your license agreement(s).

AppDynamics Artifacts End of Maintenance and Support

Artifacts are generally available AppDynamics agent and platform components on the AppDynamics Downloads Portal or AppDynamics Accounts Downloads. 

Artifact end of maintenance and support dates are one calendar year after the next generally available artifact release. For example, the .NET Agent 20.11 has an end of maintenance and support date of December 18, 2021 because 20.12 released on December 18, 2020.

Hotfixes are not considered major releases, and therefore do not affect the end of maintenance and support dates. Certain AppDynamics platform components have diverged from calendar versioning, such as the Events Service.
