Changed in release 2.42 (10th May 2021)
---------------------------------------

Artwork editor :

  o It is possible to create a PCB by placing parts on the board, and then sketching in the required
    connectivity using the Amend and Mroute tools.  However, it is not possible to easily create a
    net list from such designs, and this makes it impossible to utilise the artwork validation tool to
    properly check the design for clearance errors.

    To assist with this use case, a new tool "Check->Build Netlist from Artwork" has been added to the
    artwork editor.  This tool traces the artwork connectivity in a similar way to the artwork validation
    tool, and then creates a net list from the traced result.  After the netlist is created, it is then
    possible to use the artwork validation tool to check the design for clearance errors.

    Also, by opening the resultant netlist in the netlist editor, it may then be exported in a variety
    formats into external programs such as spreadsheet editors.

    The netlist building tool cannot create a netlist where some connections are made using a power plane.

    When executed, the netlist building tool DESTROYS any previous netlist before creating its own.
    (Accidental destruction of your existing netlist is avoided by the tool first displaying a popup warning
     dialog, and requires the user to tick a confirmation checkbox before the tool can be executed.)

    
Netlist editor :

  o The ability to save files in .CSV format has been added to the "File->Save Nets List as Text" dialog.
    Also added checkboxes to control the inclusion of option columns and the section start/end kewords.
