As far as I know, only the Book plugin is affected.
I suspect that maybe all my plugins can be affected by this, since they all use the same method from Eli Book to get the plugin name. So, as I keep updating them, I'm already changing to get the plugin name by a string. The thing is, it may take a while, because I have a lot of plugins =/
If you want, you can try to put a compatibility warning somewhere you see fit on your tools, in case the user has any problems, he just need to open the plugin file and replace:
Eli.PluginManager.getPluginName() with the plugin filename, without the extension: "EliMZ_Book".
As I update my plugins, I'm putting on the update log that I already made this fix to be compatible with your tools.
