SOLR 7.x stable version

[abhi Abhishek]

Hi All -
     I am using SOLR Cloud v6.5.0 and looking to upgrade it to SOLR 7.x;
any suggestions which are the most stable version in SOLR 7.x series.
from my initial reading, I see until SOLR 7.2 we had issues with CDCR
updates.

Thank you for your suggestions.

Thanks,
Abhishek
