 In [Arch Linux](https://www.archlinux.org/), the database structure on [tests.reproducible-builds.org](https://tests.reproducible-builds.org/) was changed and the testing jobs updated. Work has been started on a verification test job which rebuilds the officially released packages and verifies if they are reproducible or not. In the "hacking" time after the summit, several packages were made reproducible, raising the amount of reproducible packages by approximately 1.5%. For example [`libxslt`](https://www.archlinux.org/packages/extra/x86_64/libxslt/) was patched with the patch adopted from Debian and openSUSE.
 
+The [Yocto Project](https://www.yoctoproject.org/) is pleased to announce that it has now implemented and is regularly running [tests](http://git.yoctoproject.org/cgit.cgi/poky/tree/meta/lib/oeqa/selftest/cases/reproducible.py) on the reproducibility of its output. These can be seen as a line item in our "oe-selftest" test runs on our [autobuilder](https://autobuilder.yoctoproject.org/typhoon/#/console). In October in our 3.0 biannual release this was for minimal images, now this has been extended to our sato graphical images in current development. The tests are generic, available for our users to use against their own images and our plan is to extend this to cover all our core recipes over the next months.
+
+Of particular interest is the fact that Yocto Project builds allow builds in arbitrary paths yet produce binary identical output and that new technology in the system uses output comparisons to allow more efficient builds through reuse of previously built objects. This topic was covered in a [recent LWN article](https://lwn.net/Articles/804640/).
