Problems with Symbols, High Severity (2)

	Change	Effect
1	Type of return value has been changed from void to mwEncryptItem* (4 bytes).	Layout of parameter's stack has been shifted by 4 bytes because the return value became passed in memory as the hidden first parameter. All the parameters will be incorrectly initialized by applications.

mw_cipher.h
[+] struct mwCipher (2)

	Change	Effect
1	Base type of field accept has been changed from *void()(mwCipherInstance)* to *mwEncryptItem()(mwCipherInstance)**.	Replacement of field base type may indicate a change in the semantic meaning of the field.
2	Base type of field offer has been changed from *void()(mwCipherInstance)* to *mwEncryptItem()(mwCipherInstance)**.	Replacement of field base type may indicate a change in the semantic meaning of the field.
