No matter what version you use, you only need to download the patch that you want to upgrade.
If you want to play game 3826 3840 3887 in haofang, it is the most common for the time being.

PS: If you want to downgrade the version later, it will cause the game main menu interfacePossibleThere will be issues such as no friend list in the lower left foot and no tank witch in the first 4 off after the master is enabled (of course, I will modify the script and ignore it --) therefore, it is not recommended to downgrade the version later.
