			// Improvement: Copying a part with no name and no value should produce a part with no name and no value.
			// New feature: Flying wires.  Automatically generated between "Pad (Flying Wire)" objects.
//"2.06";	// Bug fix: In Rendering Options, the "Show closest tracks" box was not being hidden when minimum separation was same as Gap size.

//"1.33";	// New feature: Allow horizontal veroboard strips.
//			// Tweaked color assignment algorithm.
//"1.32";	// New feature: "File->Open (merge into current)".
//"1.31";	// Improvement: User-defined areas select tracks as well as components.
//"1.30";	// Improvement: Duplicating components copies their Value too if it's different to the name.
//			// Added more component types. (Relays, Switches, Trimpots).
//			// Changed default lengths of resistors and diodes to 400 mil.
//			// Updated gEDA/TinyCAD import code for RESISTOR/DIODE/CAP_CERAMIC/CAP_FILM
//			// so that appending an optional integer number to the footprint name
//			// sets the length in 100s of mil. (e.g. RESISTOR3 = 300mil)
//			// Updated gEDA library with resistors and caps of different lengths.
//			// Added ability to select components/wipe tracks within area (hold down "R" to draw areas).
//"1.29";	// Added Crystal component type and gEDA library symbol.
//"1.28";	// Improvements:
//			// Added "Toggle Grid" and "Toggle Mirror" as View menu items.
//			// List part types in B.O.M.
//			// Allow pin labels for TO packages as well as DIPs, SIPs.
//			// New feature: Added "Parts/Templates Dialog" so user can build a parts library
//			// for ICs and TO packages (avoids defining pin labels with each new circuit).
//			// Double-clicking on any listed part adds it to the circuit.
//"1.27";	// Bug fix: Deleting a component was not immediately updating the Bad Nodes lists.
//			// Bug fix: V1.26 allowed components to be dragged while user was painting pins.
//"1.26";	// Bug fix: Holding down "P" and SPACE at the same time would allow mouse move to modify component pins.
//			// Usability tweak: Holding down SPACE now allows un-painting the board under a placed component pin,
//			// or painting the board under the pin to match the existing NodeId on the pin.
//"1.25";	// Usability tweaks:
//			// Slow down the grid auto-pan/resize when moving components with the mouse.
//			// Selecting a NodeID in the "Broken" list should also highlight it in the "Floating" list if it's there.
//			// Added a Spin FV-1 IC and serial EEPROM to the gEDA library.
//"1.24";	// Added IC Pin Labels dialog.
//"1.23";	// Fixed memory leak on shutdown.
//			// Updated Tutorial 19 with info on creating a registry key for MS Windows.
//			// Added more JFETs to the symbol libraries.
//"1.22";	// Added command line options to specify VRT file and path to VeroRoute home directory.
//			// Support drag and drop of VRT files from file explorer.
//			// Allow multiple VeroRoute instances to run at the same time.
//			// Improved error reporting during netlist import.
//			// Added color saturation slider.
//			// Changed rendering behaviour when clicking on an item in the Broken list.
//			// Added gEDA symbol libraries.
//"1.21";	// Improved rendering speed by avoiding pointless repaints.
//			// Control dialog rearranged so a checkbox controls ground-fill.
//			// Draw foil capacitors with thinner shape to better match the footprint.
//			// Draw floating component text in red.
//			// Made export to PDF centre on grid bounds instead of circuit bounds.
//			// Write status bar messages.
//"1.20";	// Added Grid checkbox.  PDF shows bounding box and can show grid.
//			// Increased max pins per component to 255.
//			// When writing to file, append ". vrt", ".pdf", ".png" to filename as needed.
//"1.19";	// Add separate "Paste" and "Paste+Tidy" buttons for auto-routing.  Updated tutorials.
//"1.18";	// Bug fix: Info dialog edits weren't treated as changes so "Save" was broken, but "Save As" was OK.
//"1.17";	// Added ground-fill.
//"1.16";	// Fixed mouse-wheel behaviour on windows.  Added View menu option to show IC pins as numbers.
//"1.15";	// Added more Edit menu items.  Check for Tutorials and History folders at start-up.
//"1.14";	// Added Help menu item to check if a new version is available.
//"1.13";	// Bug fixes: PDF write was broken since V1.10.  "Add" menu item was enabled when view was mirrored.
//"1.12";	// Fixed TinyCAD package names for NP capacitors.  Make netlist import allow spaces in Name and Value fields.
//"1.11";	// Fixed crash on importing unknown package.  Increased maximum number of pins per component to over 200.
//"1.10";	// Added import of netlist from TinyCAD schematic.  Hide old Import/Export.
//"1.01";	// Added scroll bars.  Place new components in top-left of visible view and float them if needed.
//"1.00";	// Disable component text buttons when appropriate.  Tidy code.  Drop Beta.
//"0.999";	// Bug fix: Fix possible crash if adding new wire while auto-routing is enabled.
//"0.998";	// Bug fix: After "Paste" auto-routed wire, color should stay on board when wire moved.
//"0.997";	// Added part type combo.  Added width buttons for DIP gap resizing instead of "E","R" keys.
//"0.996";	// Bug fix: Deleting grouped components could cause a crash later.  Allow DIP gap resizing with "E","R" keys.
//"0.995";	// Check if circuit has been saved before launching Tutorials.  Don't auto-raise Info window on Undo/Redo.
//"0.994";	// Bug fix: Erasing under floating pins while auto-routing.
//"0.993";	// Routing improvement.
//"0.992";	// Improve routing.
//"0.991";	// Bug fix: Redraw when toggling track styles.
//"0.99";	// Added new part types including multi-pole switches.
//"0.981";	// Bug fix: Undo/Redo.
//"0.98";	// Added Undo/Redo.
//"0.97";	// Added new part types.  Improved TO-92 outline.  Auto-centre when writing to PDF.
