Issues solved in this release:

• Running scylla_setup on CentOS 7, resulted with Scylla setup failed for `ImportError: No module named 'yaml'`. The root cause is a change in EPEL that broke the scylla_setup Python Script #4379
• nodetool cleanup may double the used disk space while running #3735
• Schema change statements can be delayed indefinitely when there are constant schema pulls #4436
• Serialization of decimal and variant data types to JSON (in SELECT JSON statements) can cause an exception on the client side #4348
• row_cache: potential abort when populating cache concurrently with MemTable flush #4236
