Code for Croatia staging version upgrade


Code for Croatia is currently running on Code for Philly Laddr hosting - on parent v2 laddr us. We have staging and production instance.

We would like to do some upgrades and testing on new Laddr releases.

How can I check what is the Laddr version on each instance?
Can I find version/release somewhere in /site-admin/?

p.s. now sure if I posted this in right category. Best suited would be “Support” but I could not find it.
