Plugin\ZorroMT4.dll differs from ZorroMT4.zip\Libraries\ZorroMT4.dll. Is that intended? Which one should be copied to MetaTrader 4 MQL4\Libraries directory? According to the manual ZorroMT4.zip is the way to go, but I suppose that it is a mistake that the ZorroMT4.dll was not updated in the zip file for this release, right?
At least in Zorro 1.83 the dll in the Plugin folder and the one in ZorroMT4.zip were identical.
