Fluentd v0.12.5 is released

Hi users!

We have just released Fluentd version 0.12.5. Here are the changes:

New features / Enhancement

• in_tail: Enable multiline mode if format contains 'multiline': #545
• event: Improve EventStream#to_msgpack_stream performance: #549
• engine: Add tag information to emit log

Bug fixes

• Update msgpack dependency to avoid incompatible encoding problem: #550

Update msgpack-ruby dependency to v0.5.11 or later.

We found msgpack-ruby v0.5 has a bug when object has a large string. Old msgpack-ruby v0.5 raises Encoding::CompatibilityError in this case.

Fix commit: Fixed Encoding::CompatibilityError under certain condition.

If you see above error in fluentd logs, we recommend to update msgpack to latest version.

multiline mode support in in_tail

Since this version, in_tail uses multiline mode when format contains multiline word. CSV example is in #543 PR. Any API feedback is welcome!

Fluentd v0.10.60 is also released with same changes.

Happy logging!
