Hi Sachin, The 1.20.1 release was voted on and passed [1] this week. So it should be released in the very near future. It contains many bug and security fixes, so for production deployments I think it would be worth moving to that version. The 1.20.x series will be a long term support release so you can stay with that while the 2.0 release is tested by the community.
Hope that helps.
