Gabe Aul has confirmed it,
@aditya_shubhra Yes, we're working on a new build with fixes for the issues we saw with .29

Now as per a new tip received by us it may be Build 10586.36 that may be pushed next. This build is seen on BuildFeed and was compiled on December 10. While this certainly looks like one of the release candidates, Microsoft may push some other build too.
Build 10586.36 may be pushed to non-insider devices subsequently if found satisfactory on Preview devices.
