Let's say next release is Release-1.10
1. We merge Feature A and Feature B to it.
2. Feature A is tested and ready to be deployed. Feature B is not.
3. You either revert Feature B commit OR re-create the release branch with only Feature A.
4. Deploy the release branch.
5. Merge the release branch in to master.
This is exactly what we do at my current workplace where we have 4 developers working on changes with different release schedule.
