Problems with Data Types, Medium Severity (9)

	Change	Effect
1	Field full_errmsg has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

	Change	Effect
1	Field dbi_inst has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

	Change	Effect
1	Field finalize has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
2	Field release_savepoint has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
3	Field rollback_to_savepoint has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
4	Field savepoint has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

Problems with Data Types, Low Severity (4)

	Change	Effect
1	Size of this type has been changed from 56 bytes to 60 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 32 bytes to 36 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 96 bytes to 124 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Base type of field goto_row has been changed from int()(dbi_result_t,unsigned long long) to int()(dbi_result_t,unsigned long long,unsigned long long).	Replacement of field base type may indicate a change in the semantic meaning of the field.

Problems with Symbols, Low Severity (1)

	Change	Effect
1	3rd parameter errno has been renamed to err_no.	Renaming of a parameter may indicate a change in its semantic meaning.

Problems with Constants, Low Severity (2)

	Change	Effect
1	The value of constant LIBDBI_LIB_AGE has been changed from 0 to 1.	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 LIBDBI_LIB_CURRENT has been changed from 1 to 2.	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.
