- bugfix: fixed crash if library closed and any key pressed while library browser in focus

- enhancement: implemented 'geomMargin()' DRC check. This checks the spacing from the vertex of a pair of concave edges of a polygon to an adjacent 'contained' rectangle's nearest vertex. The (non-manhattan) distance is required to be larger than the square root of the minimum spacing rule between the shapes due to lithography effects (e.g. ink flow in a printed electronics design).

- enhancement: Importing a techfile now deletes any existing MPP definitions in a library.

- bugfix: exporting a techfile writes correct MPP syntax.

- bugfix: Using the middle mouse drag during e.g. a move command to pan as you move now works as expected.

- enhancement: Export CDL can lump small parasitics on the same net together into a single parasitic.

Version 4.3.51 release on 19/08/2013

- bugfix: Alpha blending was never working on the non-OpenGL version of Glade; it was not properly supported in Qt 3.x, and in Qt 4.x there is a problem if you store colours as QRgb values rather than as QColours. This has been fixed, so the full power of alpha blending can be used on non-OpenGL use. As a result, the 'Opacity' toolbar has been removed, as its purpose is less than useful if you can set transparency by layer. Try changing some of your layers e.g. poly and metal1 to have an alpha value of 128, and set their fill patterns to be solid.

Version 4.3.52 release on 02/09/2013

- bugfix: On the OpenGL version the colour of the cursor, ruler, and moving instance box were not being shown due to a bug introduced in 4.3.51.

- enhancement: extraction of MOS devices will try and connect the source of a device to a power/ground net (depending on device type) rather than the drain.
