stunagent.h
[+] struct stun_agent_t (1)

	Change	Effect
1	Type of field sent_ids has been changed from StunAgentSavedIds[20] (960 bytes) to StunAgentSavedIds[200] (9600 bytes).	1) Size of the inclusive type has changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.
