Upgrade to version 18 needed to process W2s thru Aatrix

We are using Aatrix to process our W2s and I want to know if I need to update my software prior to doing this.  We are currently running 17.1.8 and I've been reading about a lot of issues with version 18.  I want to get W2s processed prior to closing the year and updating to version 18 (in prep of processing my 2020 payroll this weekend). 

So.....do I need to update to use Aatrix for 2019 W2s? 

Thank you in advance.
