Fluentd v0.14.23 has been released

Hi users!

We have released v0.14.23. This release is mainly for bug fix.

Here are the changes of v0.14.23(full ChangeLog is available here)

in_udp: Add remove_newline parameter

Current in_udp removes the newline from the end of incoming payload. This is for one line log processing. But originally, UDP is message-oriented and no need such processing. In addition, this behaviour is not good for binary message.

So we add remove_newline parameter to control this behaviour. Default is true for the compatibility, but we will change the default value to false after 6-months transition period.

Major bug fixes

• in_tcp: Fix log corruption under load.

in_tcp shared the buffer between connections and it has a log corruption problem under high load. New implementation has a buffer inside the connection so the problem is fixed.
Patch from @AM-iain. Thanks!

• out_forward: Fix elapsed time miscalculation in tcp heartbeat

TCP heartbeat misjudges the server failure when one of server in <server>s has a problem. It causes detaching active destination from target server list. We fixed this problem by changing elapsed time calculation routine.
UDP heartbeat doesn't have this problem.

We will release v0.12.41 with several backports soon.

Enjoy logging!
