Fluentd v1.14.1 has been released

Hi users!

We have released v1.14.1. ChangeLog is here.

This release is a maintenance release of v1.14 series.

We recommend to upgrade Fluentd because it contains fixes about in_tail crash bug.

in_tail: Fixed a crash bug that it raise undefined method of eof? error

In this release, one of in_tail plugin bug was fixed.

This crash bug will happen only when read_bytes_limit_per_second was specified. read_bytes_limit_per_second parameter was introduced since Fluentd v1.13.0, so it affects v1.13.0 or later with read_bytes_limit_per_second was specified.

If you don't use read_bytes_limit_per_second configuration parameter at all, it has nothing to do with it.

Fixed a error when using @include directive

If you use the following example, it causes an unexpected error.

@include "https://raw.githubusercontent.com/fluent/fluentd/master/example/in_forward.conf"

The error occurs when http or https scheme URI is used in @include directive with Ruby 3. On Ruby 2.7, it raise an warning message (using deprecated method), not an error.

out_copy: Fixed to suppress a wrong warning for ignore_if_prev_success

Because of internal inappropriate conditional handling, even though a user set ignore_if_prev_success, it doesn't work as expected.

Instead, it emits the following warning.

2021-09-24 14:10:54 +0900 [warn]: #0 ignore_errors are specified in all <store>, but ignore_if_prev_success is not specified. Is this intended?

This behavior was fixed.

Upgrade attention for TD Agent users

If you use Fluentd v1.12 or later, we recommend to use at least v1.12.4. It is because in_tail contains serious bugs in it.

As latest td-agent 4.2.0 bundles Fluentd 1.13.3. If you want to upgrade Fluentd further more, upgrade it by yourself.

$ sudo td-agent-gem install fluentd --version=1.14.1

Enjoy logging!
