Got a response from them yesterday:

We still haven´t any ETA for the JoomSEF compatibility with the newest Joomla. We suppose it could be done this or next month.

Thank you.

With kind regards,

Hello,

It's been a few days, are there any plans for fixes to the Jomsocial plugin as well as adding Joomla 3.7+ compatibility?

Hello,

I would like to know if there is an ETA for Joomla 3.7 compatibility? Also there seems to be an issue with user aliases in Jomsocial, plugin version 3.1.23, when a user updates their profile alias, the plugin doesn't trigger any sort of update. Cron is enabled to update URLs and seems to not have any effect.
