Problems with Constants, Low Severity (3)

	Change	Effect
1	The value of constant CIB_LIBRARY has been changed from "libcib.so.2" to "libcib.so.3".	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.
