Problems with Symbols, High Severity (1)

	Change	Effect
1	Parameter maxtv of type timeval* 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.

[+] ares_timeout ( ares_channel channel, timeval* tv ) (1)

Problems with Data Types, Low Severity (2)

	Change	Effect
1	Field tcp_port has been added to this type.	NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Field port has been renamed to udp_port.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

Problems with Symbols, Low Severity (2)

	Change	Effect
1	Base type of 6th parameter buf has been changed from char to unsigned char.	Replacement of parameter base type may indicate a change in its semantic meaning.

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

[+] ares_timeout ( ares_channel channel, timeval* tv ) (1)

to the top

Problems with Constants (3)

	Change	Effect
1	The value of constant ARES_OPT_DOMAINS has been changed from (1 << 6) to (1 << 7).	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.

	Change	Effect
1	The value of constant ARES_OPT_LOOKUPS has been changed from (1 << 7) to (1 << 8).	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.

	Change	Effect
1	The value of constant ARES_OPT_SERVERS has been changed from (1 << 5) to (1 << 6).	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.
