What is the process and cadence around new releases of iVectorOne? Do we test new functions before they go live?

iVectorOne has major releases between 1 / 2 months. We share release notes with you describing what is in those releases.
 
There will also be minor bugfix releases which we don't share release notes for, but will inform on the relevant tickets for those releases.
 
As iVectorOne is a SaaS product, you don't have a test environment to test functionality or new releases in, but you have a test account within the API - we would test the new functions on our side before a release.
