+We will be newly using [png](https://github.com/openSUSE/branding/pull/149) for the default wallpaper set on
+[openSUSE](https://www.get.opensuse.org/) Tumbleweed, and upcoming versions of openSUSE Leap, and Leap Micro.
+
+The driver behind the decision is the unification of wallpaper paths with SUSE Linux Enterprise via a compatibility symlink, however, the format had to be the same.
+SLES and SLED have been using PNG since the last rebrand in 15 SP3, and openSUSE has been using JPG up until now.
+
+Using a common default wallpaper path allows applications utilizing wallpaper or similar system branding to be re-run on SLES and openSUSE without a need to be rebuilt.
+The small price for using the lossless format is a slight increase in size, however, we do use [optipng](https://github.com/openSUSE/branding/pull/148/files#diff-76ed074a9305c04054cdebb9e9aad2d818052b07091de1f20cad0bbac34ffb52R80) so it's within units of megabytes for all wallpapers resolutions combined.

+``` 
+
+We've also supplied new [apple-touch-icon](https://github.com/openSUSE/distribution-logos/pull/7/files) which was part of SUSE Linux Enterprise distribution logos and was missing on openSUSE side.
+
+<strong>Since this is effectively a change of a default wallpaper we recommend users who use the default wallpaper to log out and log in to avoid any glitches.</strong>
+And ensure that system was able to re-read `/usr/share/wallpapers/openSUSE-default-static.xml`
+
+The great news is that we plan to come up with a new wallpaper collection for openSUSE Leap 16 as well as openSUSE Tumbleweed, which haven't seen wallpaper change for a while, so this can be seen as a nice little fire drill.
