Oh! You're correct, it used to be in there, it's not now. Also, there seems to be another issue with this last update, and the name of the folder created when you unzp the zip file on OSX. I'll update and post here. Sorry about this!
Okay, the folder for ManaWriter should be correct in the zip now, and the readme.txt is there. Just download the lastest version of the file. Any other issues, please let me know
