From the node dashboard in the app, after logging into your dashboard: under the header where it says “Stellar Horizon Mainnet Shared”, there are four fields:
“Horizon Watcher” | “Mainnet” | “stellar-core 13…4a” | “1.5.0-255b12ef9…168”
The last two are the versions of Core and Horizon, respectively, running on the shared node. You can hover over them to get the full display with hash.
Core is v 13.2.0
Horizon is 1.5.0
