• PCB exposure:
  • (Fix) Gerber X2 attributes (%TO, %TA, %TD) and other unsupported extended commands were parsed as
    coordinates and D codes, a net or component name like TX0, Y1 or D12 drew phantom copper or changed the aperture,
    dropping the next pads and tracks (#1159).
  • (Fix) Gerber arcs exact to the file resolution were rejected, mostly small arcs in inch files with few
    decimals (Eagle 2.4), and the next track then started from the arc start. An arc that can't be resolved is now drawn
    as a straight segment and still moves to its end point.
  • (Fix) Gerber aperture macro primitives were rotated clockwise instead of counterclockwise, and the
    center line rotation was rounded to whole degrees.
  • (Fix) defining a Gerber aperture also selected it, the following tracks and pads used the new
    aperture instead of the selected one.
  • (Fix) Gerber aperture macros flashed with clear polarity (%LPC) added copper instead of clearing it.
  • (Fix) Gerber aperture holes and macro parts with the exposure off erased the copper under them, and
    a clear flash with a hole added copper in the hole. They now show what is under them.
  • (Fix) Gerber rectangle pads were one pixel larger on each axis, and with "Size scale" they grew to the
    right and down only instead of staying centered.
  • (Fix) Gerber coordinates with a + sign were ignored, and only the first command of an extended block
    with several (%FSLAX24Y24MOIN%) was read, so such inch files were read as millimeters.
  • (Improvement) unsupported Gerber commands that change the image (step and repeat, block apertures,
    aperture mirroring, rotation and scaling) are recorded in GerberFormat.UnsupportedCommands.
• (Add) 3D preview: zoom level on the toolbar, relative to the whole model fitting the view (1x), click to fit the
  model to the view.
• (Add) 3D preview: "Auto zoom & center issues" setting (on by default), independent of the layer preview one. When
  off, selecting an issue centers the camera on it keeping the zoom. Hold [ALT] while selecting the issue to invert
  the behavior.
• (Add) Issues: "Group each island with the floating parts resting on it" setting (off by default). The pixels of an
  island no longer support the layer above, everything that rests only on an island is floating too and is shown with it
  as a single island issue, from its lowest layer, the one to support, up to where it joins the supported model.
  Islands that join each other are merged in the same issue, and removing the issue removes the whole floating part.
  The repair tool still works on each island alone. Also available in the command line as print-issues --group-islands (#1047).
• (Fix) About window was showing available ram instead of used ram.
• (Fix) Typos in OSLA documentation by @hamidzr (#1160)
• (Upgrade) .NET from 10.0.12 to 10.0.13
