Upgrading instructions (If you want to update from Gunbot v10 and you want to keep your old settings instead of doing a fresh install)
Download the update and unpack it to a new folder, copy the config.js and gunbotgui.db files from your previous v10 installation into the new folder to keep your settings. In case you used https for the v10 gui, also make sure to copy both the key and certificate files to the new folder.
New strategy parameters for v11 will be automatically added through the gui the first time you update a strategy.
Due to new libraries used, you cannot simply overwrite the executable for this release.
