Dynamics SL 2018 and MS SQL Server 2019

SQL 2019 has recently been released. I've a client who will be upgrading to SL 2018 in the next couple of months. Since they are responsible for upgrading the SQL Server (didn't purchase the run-time,) their IT provider has asked if SL 2018 will work with the latest version of SQL.

I looked at the System Requirements documentation yesterday (fresh download from PartnerSource,) and it doesn't mention SQL 2019. A quick Google search also failed to uncover any concrete answer. Has anyone seen an answer to this from Microsoft? Or perhaps (doubtful) tried it yourself?

Thanks for any help!
