Problems with Data Types, High Severity (1)

	Change	Effect
1	Size of this type has been changed from 552 bytes to 560 bytes.	Layout of parameter's stack of several functions has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

readproc.h
[+] struct proc_t (1)

to the top

Problems with Data Types, Medium Severity (3)

	Change	Effect
1	Field maj_delta 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 min_delta 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	Type of field name has been changed from char[64] (64 bytes) to char[128] (128 bytes).	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

readproc.h
[+] struct proc_t (2)

[+] struct slab_info (1)

to the top

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Size of this type has been changed from 104 bytes to 168 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

slab.h
[+] struct slab_info (1)

to the top

Problems with Constants, Low Severity (1)

	Change	Effect
1	The value of constant SLAB_INFO_NAME_LEN has been changed from 64 to 128.	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.

slab.h
[+] SLAB_INFO_NAME_LEN

to the top

Other Changes in Constants (1)

	Change	Effect
1	The constant PROC_EDITENVRCVT with value 0x40000 has been added.	No effect.
