当初は2019/4/26を予定していたYocto2.7(warrior)ですが、2019/5/1(PDT 15:35:23)にリリースのアナウンスが有りました。
2019年4月14日にコミットされたものがQAを経てのリリースとなっています。

本日（日本時間2019年5月7日15:00)現在、git で branch warrior で指定したものは　bitbakeのユーザーマニュアルに
追記がありますが、レシピの変更等は発生しておりません。

今回のリリースでは、従来yocto project でpokyと同時にリリースされていたmeta-qt4/meta-qt3
eclips-plugin の提供の中止となっています。

Known Issues
-------------
Bug 13309: qemuppc fails to shutdown intermittently
https://bugzilla.yoctoproject.org/show_bug.cgi?id=13309

Bug 12991: Bitbake build-appliance-image fails during building image due to webkitgtk package
https://bugzilla.yoctoproject.org/show_bug.cgi?id=12991

Late in the release we found there an issue with the TCP backlog
queue coalescence changes in the 5.0 kernel which was the cause of a
couple of python3 ptest hangs. A fix is available upstream, and will be
ported to the 5.0.X stable kernel series. This is already in our master
branch and will be in our point release. We don't believe it to be
serious enough to warrant holding the release, particularly given
the spread of kernel versions people use.

------------------
License Compliance
------------------
The following corrections have been made to the LICENSE values set by recipes:

* socat: corrected LICENSE to be GPLv2 rather than GPLv2+
* libgfortran: Set license to GPL-3.0-with-GCC-exception
* elfutils: removed Elfutils-Exception and set GPLv2 for shared libraries
