There seems to be a lot of SCSI changes in 4.19. Based on looking at the latest discussion in the Linux SCSI development, I believe there are several significant mpt3sas changes made:

mpt3sas: Separate out mpt3sas_wait_for_ioc
mpt3sas: Refactor mpt3sas_wait_for_ioc function
mpt3sas: Call sas_remove_host before removing the target devices
mpt3sas: Fix Sync cache command failure during driver unload
