Problems with Data Types, High Severity (2)

	Change	Effect
1	Field arg0 has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 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 sval has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 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, Medium Severity (2)

	Change	Effect
1	Field match_ln has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.
2	Field match_sh has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.

Problems with Data Types, Low Severity (3)

	Change	Effect
1	Field flags has been added to this type.	Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Size of this type has been changed from 32 bytes to 24 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 40 bytes to 36 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Problems with Constants (1)

	Change	Effect
1	The value of constant HXOPT_AUTOHELP has been changed from {NULL, '?', HXTYPE_NONE, NULL, NULL, HX_getopt_help_cb, 0, NULL, "Show this help message"} to {NULL, '?', HXTYPE_XHELP, NULL, NULL, HX_getopt_help_cb, 0, "Show this help message"}.	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.
