Added Symbols (1)

candidate.h, libnice.so.10.0.0
nice_candidate_copy ( NiceCandidate const* candidate )

to the top

Problems with Symbols, High Severity (1)

	Change	Effect
1	Parameter candidate_identifier of type char const* has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

ice.h, libnice.so.0.9.0
[+] stun_usage_ice_conncheck_create ( StunAgent* agent, StunMessage* msg, uint8_t* buffer, size_t buffer_len, uint8_t const* username, size_t const username_len, uint8_t const* password, size_t const password_len, bool cand_use, bool controlling, uint32_t priority, uint64_t tie, StunUsageIceCompatibility compatibility ) (1)

to the top

Problems with Symbols, Medium Severity (4)

	Change	Effect
1	Parameter has_padding of type bool has been added to the calling stack.	This parameter will not be initialized by old clients.

	Change	Effect
1	Parameter initial_timeout of type unsigned int has been added to the calling stack.	This parameter will not be initialized by old clients.
2	Parameter max_retransmissions of type unsigned int has been added to the calling stack.	This parameter will not be initialized by old clients.

	Change	Effect
1	Parameter initial_timeout of type unsigned int has been added to the calling stack.	This parameter will not be initialized by old clients.

stunmessage.h, libnice.so.0.9.0
[+] stun_message_validate_buffer_length ( uint8_t const* msg, size_t length ) (1)

timer.h, libnice.so.0.9.0
[+] stun_timer_start ( StunTimer* timer ) (2)
[+] stun_timer_start_reliable ( StunTimer* timer ) (1)

to the top

Problems with Data Types, Low Severity (5)

	Change	Effect
1	Value of member NICE_COMPATIBILITY_LAST has been changed from 3 to 5.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

agent.h
[+] enum NiceCompatibility (1)

stunagent.h
[+] enum StunCompatibility (1)

	Change	Effect
1	Value of member STUN_COMPATIBILITY_LAST has been changed from 2 to 3.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
