memcached.h
[+] enum memcached_return (7)

	Change	Effect
1	Value of member MEMCACHED_DELETED has been changed from 21 to 22.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
2	Value of member MEMCACHED_MEMORY_ALLOCATION_FAILURE has been changed from 16 to 17.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
3	Value of member MEMCACHED_NOTFOUND has been changed from 15 to 16.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
4	Value of member MEMCACHED_NO_SERVERS has been changed from 19 to 20.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
5	Value of member MEMCACHED_PARTIAL_READ has been changed from 17 to 18.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
6	Value of member MEMCACHED_SOME_ERRORS has been changed from 18 to 19.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
7	Value of member MEMCACHED_VALUE has been changed from 22 to 23.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
