    A button 'Bike Info' was added to the main page which reveals additional information on the selected bike and/or the
    way the data for it was verified. The shown manuals or specifications are available for site-supporters.
► New Chain Links Calculator for Generic Final Drive was added.
    You can now calculate the number of chain links needed without loading a specific bike by entering the front-
    and rear-sprocket teeth, the chain pitch and the desired sprocket distance.
► The existing part for calculating the sprocket distance of a loaded bike was enhanced.
    For a loaded bike you can now enter the percentage of wear of your current and custom chain which will result in
    more accurate sprocket distance calculations.
► Print functionality was added.
    Now all main page results as well as all graphs can be printed (without printing ads and buttons).

    The Overall & Total Ratio page now also shows the Primary ratio, the Final drive ratio and the Gearbox ratio for all
    gears and is shown on a dedicated page using a dedicated button on the main page.
► Menu option Help-Info was split up into 2 options; Help and Tech-Info.
    In order to make navigation easier one menu-level was removed and a new option was added at the same level.
► Bug-fixes, updated Help-pages, Frames removed.
    Small (program behavior) bugs were fixed and all help pages were reviewed. Please send improvement suggestions.
    Frames were removed so less redirects and faster loading pages.
