Problems with Data Types, High Severity 4

	Change	Effect
1	Field hdf_typeid 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.
2	Field native_hdf_typeid 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, Low Severity 8

	Change	Effect
1	Size of this type has been changed from 24 bytes to 16 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 16 bytes to 4 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field atts_not_read has been renamed to atts_read.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Size of this type has been changed from 112 bytes to 88 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field coords_read has been added to this type.	1) This field will not be initialized by old clients. 2) 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 248 bytes to 256 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
3	Field atts_not_read has been renamed to meta_read.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.
