So far, Simdock used GConf to store its configuration. But GConf is finally really going away, including being removed from some distributions like Void Linux (see #17). With this release, Simdock uses WxConfig instead, which is likely to provide a stable config mechanism for years to come.
With GConf gone there was no known way to migrate the old settings. That is why the major version number was increased. Thankfully the starters were stored separately in ~/.simdock/, a mechanism that was independent of GConf and continues to work as before - the old starters are not gone.
