You can now set the MAXDOP option on each database differently:
ALTER DATABASE SCOPED CONFIGURATION SET MAXDOP = 1;
Replacement for DBCC INPUTBUFFER:
sys.dm_exec_input_buffer()
Replacement for Trace Flag 1117:
AUTOGROW_SINGLE_FILE and AUTOGROW_ALL_FILES options on FileGroupLevel
Replacement for Trace Flag 1118:
MIXED_PAGE_ALLOCATION
on Database Level ^^.
