FP19 will be based on 22q4 release. There is few important items from 23q1 included, but not all. If there is some critical afterwards, then we consider making hotfixes.
Good news. We have accepted FP19 to release and I will upload the package to Sinch download site soon. Likely it will happen tomorrow and same time we will update documentation page as well.
Customers with Sinch agreement can request access to download site via ticket. For the access we need your email and mobile phone number (for one time password)
Meanwhile the FP19 will continue to SAP security checking and will be released to SAP Market Place when we have final stamp from SAP. I cannot promise or estimate how long the process takes.
