Precompiled zabbix_sender for AIX 6.1 returns success instead of failure

[edge]

I am getting pre v2.1.7 behaviour from latest precompiled zabbix_sender for AIX 6.1.
Since v2.1.7 zabbix_sender behaviour has changed.
Issue ZBXNEXT-935 is mentioned in changelog. Current online documentation includes notes about nonzero return codes.
Actual sources also contain SUCCEED_PARTIAL return value that should implement new behaviour.

This is what I am getting:

$./zabbix_sender -V
Zabbix Sender v2.2.1 (revision 40808) (09 December 2013)
Compilation time: Dec 27 2013 03:13:51
$./zabbix_sender --zabbix-server notexist --port 10051 --host blah --key blahblah --value somevalue; echo $? 
Sending failed. Use option -vv for more detailed output.

$./zabbix_sender --zabbix-server zabbix --port 10051 --host blah --key blahblah --value somevalue; echo $?   
info from server: "Processed 0 Failed 1 Total 1 Seconds spent 0.000035"
sent: 1; skipped: 0; total: 1

Does anybody else have the same issue?
Are there any other precompiled binaries to try?

zabbix_sender v2.1.7 and eturn codes

Just got an official answer.
New return codes will work when you use both zabbix_sender v2.1.7 and zabbix server v2.1.7.
If zabbix server version is older than v2.1.7 you won't get new functionality.
