The first changes are, as always, updated software. Libreoffice is now at version 5.0.3, Firefox has been updated to 41.0.2, and many other small packages have been updated. If you have been installing updates regularly, you will already have these updates.
The second change is one that you will likely notice. The login screen has been slightly redesigned, with several icons being replaced by less archaic-looking choices, and the background being set to a green patterned wallpaper. The goal of this change is to make the login screen appear cleaner, and less cobbled together.
Another slight change is that the wallpapers have been changed, with a few being removed and some being added. I have been meaning to make this change for several weeks now, but only just got around to it.
Finally, I have been learning to use the build script to apply settings that have previously required me to upload edited files to the builds. Using the script makes changes easier, and also means less work keeping track of files. All seems to have gone well (it should have after 16 tries) so you should not notice any unintentional differences.
Let me know what you think of the latest release. Are there any things I could add? Let me know in the comments.
