Problems with Data Types, High Severity (1)

	Change	Effect
1	Field original_subject 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 (6)

	Change	Effect
1	Field atrn 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 deliverby 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	Size of field cclientPrivate has been changed from 12 bytes to 48 bytes.	1) Size of the inclusive type has changed. 2) Previous accesses of applications and library functions to the fields at higher positions of the structure definition may be broken.

	Change	Effect

Problems with Data Types, Low Severity (13)

	Change	Effect
1	Size of this type has been changed from 40 bytes to 56 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field bmime has been added to this type.	NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Field chunk has been added to this type.	NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.

	Change	Effect
1	Base type of field expunge has been changed from *void()(MAILSTREAM)* to *long()(MAILSTREAM,char,long)**.	Replacement of field base type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Size of this type has been changed from 232 bytes to 268 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Field nokod has been added to this type.	NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
3	Field sniff has been added to this type.	NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.

	Change	Effect
1	Size of this type has been changed from 104 bytes to 108 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Problems with Symbols, Low Severity (4)

	Change	Effect
1	Base type of 1st parameter md has been changed from GETS_DATA to getsdata.	Replacement of parameter base type may indicate a change in its semantic meaning.

	Change	Effect
1	Base type of 1st parameter md has been changed from GETS_DATA to getsdata.	Replacement of parameter base type may indicate a change in its semantic meaning.

	Change	Effect
1	1st parameter oldstream has been renamed to stream.	Renaming of a parameter may indicate a change in its semantic meaning.

Problems with Constants (1)

	Change	Effect
1	The value of constant MAXUSERFLAG has been changed from 64 to 50.	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.
