Download and run the installer. Competitions created in earlier version av MeOS will be kept.

If you wish to access the same competition form several computers simultaneously, you need a computer running MySQL server. MySQL is a free database server, based on open source. MySQL was originally developed by MySQL AB, based in Uppsala, Sweden (same place where MeOS lives), but were later bought by Sun Microsystems, Inc, which in turn was bought by Oracle.

MySQL downloads

This version of MeOS is built on a new technical platform and has a new internal representation to handle character outside the Latin character set. It is therefore likely that there are new, unknown bugs. Do not use this version for important competitions without proper testing.

Please note the following: Competitions saved with this version can be opened in version 3.4 Update 1. Using an earlier version of MeOS may corrupt the competition. It is possible to install and run this version of MeOS together with MeOS 3.4 Update 1 on the same computer.
