Binary log writing speed was improved by moving checksum calculations out of the global binlog mutex. This is a contribution by Kristian Nielsen (MDEV-31273)
New system variable max_binlog_total_size enables binary log purging when the total size of all binary logs exceeds the specified threshold. The implementation is based on the patch from Percona (MDEV-31404)
FULL_NODUP is a new value for the binlog_row_image system variable. It essentially works like FULL, that is all columns are included in the event, but it takes less space, because the after image omits columns that were not changed by the UPDATE statement, and have same values as in the before image. This is a contribution from Alibaba (MDEV-32589)
