3	Name of member with value 24 has been changed from MYSQL_OPT_PROGRESS_CALLBACK to MYSQL_OPT_BIND.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

	Change	Effect
1	Size of this type has been changed from 968 bytes to 964 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Reserved field unused has been replaced by unused_0.	This field will not be initialized by old clients.

Problems with Constants, Low Severity (5)

	Change	Effect
1	The value of constant DBUG_FILE has been changed from (_db_fp_) to _db_fp_().	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant DBUG_VOID_RETURN has been changed from {DBUG_LEAVE; return;} to do {DBUG_LEAVE; return;} while(0).

	Change	Effect
1	The value of constant DEBUGGER_OFF has been changed from _no_db_=1;_db_on_=0; to do { _dbug_on_= 0; } while(0).
