About the Custom Synchronization StackPack
StackState Self-hosted v4.5.x
This page describes StackState v4.5.x. The StackState 4.5 version range is End of Life (EOL) and no longer supported. We encourage customers still running the 4.5 version range to upgrade to a more recent release.
The Custom Synchronization StackPack is meant for integrations that include a topology aspect. If your integration only has telemetry, you do not need this StackPack.
