The [New in this Version](https://docs.inductiveautomation.com/display/DOC81/New+in+this+Version) page gives some links …

- Added a new [authentication challenge action]  
([Component Events and Actions - Ignition User Manual 8.1 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC81/Component+Events+and+Actions#ComponentEventsandActions-AuthenticationChallengeAction)), [scripting function](https://docs.inductiveautomation.com/display/DOC81/system.perspective.authenticationChallenge), and [session event](https://docs.inductiveautomation.com/display/DOC81/Perspective+Session+Event+Scripts#PerspectiveSessionEventScripts-AuthenticationChallengeCompleted) to Perspective in order to better support 21 CFR Part 11 electronic signature requirements.
