The Marble team didn’t only focus on bug fixing and stability improvements for the 1.4 release. Marble users who still use TangoGPS for recording their tracks will appreciate that Marble can now load its tracking files directly without having to convert them to the .gpx format first. Flightgear addicts are now able to visualize the course of their flight sessions in Marble.
As a technical side note, Marble for Windows was compiled under Linux using Wine. So although it is a Windows application, it has never seen a real Windows installation! I might provide the details in another blog post if there is interest.
