Upgrading to DefectDojo Version 2.3.x

There are no special instructions for upgrading to 2.3.0. In 2.3.0 we changed the default password hashing algorithm to Argon2 (from PBKDF2). When logging in, existing hashes get replaced by an Argon2 hash. If you want to rehash password without users having to login, please see the Django password management docs. The previous password hashing algorithm (PBKDF2) was not unsafe, but we wanted to follow the OWASP guidelines.
