Instead of excluding all plugins but the link one on OSes other than Windows and Linux, the new approach allows for a more granular control by introducing a list of plugins that is supported on the different platforms. This replaces the globbing approach which means that new plugins have now to be included in this list explicitly. The advantage of this is that this allows for a much greater flexibility for handling plugins on different OS. Furthermore the plugin's own directory is no longer added to the include-path by default. If a plugin wishes to do this, it should do so explicitly. This should help make the plugins easier to move around in the future.
