+### Important information for people updating from version 1.2.7
+
+Due to a bug in the Software Update plugin bundled with version 1.2.7, updating
+to 1.2.8 necessitates the installation of a plugin that fixes said bug
+(through monkey patching).
+
+The plugin "Updatefix 1.2.7" can be found [in the plugin repository](http://plugins.octoprint.org/plugins/updatefix127/) and
+[on Github](https://github.com/OctoPrint/OctoPrint-Updatefix-1.2.7/).
+
+Before attempting to update your installation from version 1.2.7 to version 1.2.8,
+please install the plugin via your plugin manager (it doesn't necessitate a
+restart or even a reload). Afterwards you can update as usual. The plugin will
+self-uninstall once it detects that it's running under OctoPrint 1.2.8.
