This directory contains nightly Windows builds of the Mana client. Starting with 20100201 only one binary is used to support both ManaServ and Eathena. Starting with 2010226 Mana uses different configuration directories for each platform. See http://forums.themanaworld.org/viewtopic.php?p=85157&f=1#p85157 for more information. - mana-*-win32.exe contains the full installer package - mana-*.zip is a ZIP file containing just the binary (mana.exe) - patches.* contains all the patches used for building the package at that specific date Usually it should be sufficient to download the installer once, and just replace mana.exe in the installation directory with newer versions. If you experience any problems do a complete uninstall, and try again with the newest version available. Old builds are kept for one week.
