Check This Page for important upgrade instructions. You have to upgrade manually (means: You do not use the component installer if you already have a previous version installed, you have to upload the relevant files to the correct directory first).
If this is your first install, install through component installer as usual.
IMPORTANT: To be able to upgrade to this version, you have to upgrade to the 0.1.0 version first! But if it is your first install, just install this version. Or if you are running com_mls_events version 0.1.0 or later, just uninstall it from the components menu and install the new version. You have to make a backup of your config file.
