[rules-users] Running rules from the past

[Ansgar Konermann]

Hi,

is there a distinction between snapshot and release versions at all in
Guvnor?

If I use snapshots only (referenced by an id) from my production code, how
can I tell snapshots intended for development-only use and those for
production use apart?

How do I know which is the latest snapshot suitable for production use?

Kind regards

Ansgar
