Hello Mateo, great to hear that you are looking to use Ory Kratos!
You should use the latest release, it has gone through very thorough QA and is secure to use.
Also if you dont want to deal with the hassle of deploying and upgrading Ory Kratos yourself we offer a Ory Cloud (
#cloud) as an alternative deployment method managed by us.
You can sign up for a free account and test it out a bit:
