Approximately once a year, a new Geneious version is released. A new version (eg RX) has new features and functionality as well as improvements. If you do not have a valid subscription you must purchase an upgrade to use a newer version.
Our development team support the two most current versions of Geneious and will release updates (eg RX.X) to these versions. If you have purchased this version, or have a valid subscription the update is free.
You can read through a release history at the Previous Versions Page.
