Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Field cached_server_error 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.

Problems with Symbols, Medium Severity (1)

	Change	Effect
1	Type of return value became const (has been changed from char* to char const*).	The return value will be treated as non-const by old client applications. This may result in crash or incorrect behavior of applications.

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Size of this type has been changed from 16532 bytes to 16536 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Problems with Symbols, Low Severity (11)

	Change	Effect
1	2nd parameter stat has been renamed to memc_stat.	Renaming of a parameter may indicate a change in its semantic meaning.

	Change	Effect
1	2nd parameter stat has been renamed to memc_stat.	Renaming of a parameter may indicate a change in its semantic meaning.

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

	Change	Effect
1	Type of return value has been changed from char* to char const*.	Replacement of return type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 2nd parameter keys has been changed from char to char const.	Replacement of parameter data type may indicate a change in its semantic meaning.
2	Type of 4th parameter number_of_keys has been changed from unsigned int to size_t.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 4th parameter keys has been changed from char to char const.	Replacement of parameter data type may indicate a change in its semantic meaning.
