(cad/klayout) Updated 0.25.9 to 0.26.8 by Atsushi Toyokura <asteria.at (at) \ 
gmail.com>

 0.26.8          (2020-09-15):

  * Enhancement: %GITHUB%/issues/639
        A new method is available which enables copying of multiple cells
        into a target layout while maintaining common subcells are single
        cells.
  * Bugfix: %GITHUB%/issues/637
        Points have not been selected properly when inside mirrored subcells
        in partial edit mode.
  * Bugfix: %GITHUB%/issues/629
        Qt5 QTimer timeout signal was not available to Python or Ruby.
        This also applied to all "private" signals of Qt5. QTimer is just
        one important example for this case.
  * Bugfix: %GITHUB%/issues/617
        A problem with pseudo-const Python/Ruby objects in the netlist API
        was fixed.
  * Bugfix: %GITHUB%/issues/615
        Basic authentication for package manager now uses UTF-8 encoding.
        Most servers expect this kind of encoding today. UTF password
        characters are supported this way.

 0.26.7          (2020-07-07):

  * Bugfix: %GITHUB%/issues/381 and more
        Some bugs fixed that happened specifically on MacOS.
        1.) A segfault that happened in LVS
        2.) Some classes were not properly registered for usage in scripts.
  * Bugfix: %GITHUB%/issues/493
        LVS asserted on MacOS
  * Enhancement: %GITHUB%/issues/586
        As a safety feature, the stream writers now refuse to write layouts
        with cells carrying the same names. Writing such layers would result
        in corrupted or invalid layout files.
  * Bugfix: %GITHUB%/issues/589 (tentative)
        On Anaconda-based builds for MacOS 10.15 (Catalina) a loss of instances
        was observed. This could be traced down to compiler/library incompatibilities
        but not further.
  * Enhancements: %GITHUB%/issues/591
        Two enhancements in the macro editor:
        1.) A crash happening when adding a new location was fixed
        2.) The template selection popup can now be disabled by dismissing the
            tip dialog.
  * Bugfix: %GITHUB%/issues/592
        Reading a file into a layout with unnamed layers caused problems with
        layer mapping specs.
  * Bugfix: %GITHUB%/issues/596
        Library#_destroy was crashing the application. As this function must not
        be called, it's rerouted to "nothing" for backward compatibility.
  * Enhancement: %GITHUB%/issues/603
        The "adjust origin" feature now allows specifying the target
        coordinates for the adjustment.
  * Bugfix: %GITHUB%/issues/610
        An internal error happened for certain hierarchical configurations on
        netlist extraction.
  * Enhancement: LVS netlist compare
        The algorithm was improved to provide better reproducibility. The
        detection of matching paths in the presence of ambiguities was
        improved.
        In addition, the netlist compare now favours net names for resolving
        ambiguities. So if nets are named the same in the layout and the
        schematic, ambiguities are resolved based on these names. This is
        usually more efficient. A new function is available to turn this
        feature off: "consider_net_names(false)".

 0.26.6          (2020-06-05):

  * Enhancement: %GITHUB%/issues/522

  * Bugfix: %GITHUB%/issues/570 and %GITHUB%/issues/579
        Perimenter can be included in antenna area for the
        antenna check. This also includes a mode in which only
        the perimeter is considered.
  * Enhancement: %GITHUB%/issues/560
        A library can be associated with multiple technologies now.
  * Bugfix: width of cell and library side panels could not be
        reduced below the width of the selection boxes in the
        header
  * Bugfix: cell view selection header text did not get updated
        when saving the layout to a different file

        Macros need to be stored with CRLF on Windows for management
        with a versioning system like git
  * Enhancement: %GITHUB%/issues/411
        Multiple device extractors for same class

          - $(tech_dir) -> substituted by the directory the technology file \ 
is stored in
          - $(tech_file) -> substituted by the absolute path to the tech file
          - $(appdata_path) -> substituted by KLayout's home directory (e.g. \ 
~/.klayout)
          - $(env('X')) -> substituted by the environment variable $X
  * Enhancement: %GITHUB%/issues/406
        DRC edge layers: AND between intersecting edges gives point-like
        markers indicating the intersection points
  * Enhancement: netlist object properties
        User properties can be attached to the following netlist objects
        now: Pin, Device, Circuit, Net and SubCircuit. Properties are
        key/value pairs (keys and values can be strings can be strings
        or numbers).
        The property-enabled classes use "NetlistObject" as the base
        class now. NetlistObject provides "set_property" to set or reset
        a property and "property" to retrieve one.
        Properties are persisted in L2N and LVSDB files and written to
        layout shapes on "build_nets".
  * Enhancement: more detailed progress
        On certain nested operations, a double or triple progress bar is
        shown indicating the progress of nested operations.

 0.26.1          (2019-11-06):

  * Bugfix: %GITHUB%/issues/354
        Buddy scripts did segfault.
  * Bugfix: %GITHUB%/issues/352
        LVS: equivalent_pins required the cell to be present.

        Segfault with layer list manipulation while iterating.
  * Bugfix: %GITHUB%/issues/386
        "None" is a reserved keyword for Python binding - use \ 
"None_".
  * Enhancement: %GITHUB%/issues/382
        Possibility to copy user property value.
  * Enhancement: %GITHUB%/issues/387
        Salt: Python version can be specified in "api-version".
        Other requirements can be specified too.
  * Bugfix: %GITHUB%/issues/392
        Layers "Style" sub-pane was malformed.
  * Enhancement: %GITHUB%/issues/394
        Even bigger font sizes for rulers and labels for the 4k age:
        Now there is "XLarge", "XXLarge" and \ 
"XXXLarge" as well.
  * Enhancement: %GITHUB%/issues/393
        DRC syntax errors are now shown in their original code line
        of the DRC script.
  * Bugfix: %GITHUB%/issues/400
        Snap feature wasn't working for deep regions in certain use
        cases.
  * Enhancement: new "scale_and_snap" methods
        These methods allow scaling and snapping of layouts. Scaling
        is supported by a rational factor. After scaling, snapping can
        be applied to an integer grid. There are two incarnations.
        Region#scale_and_snap (or Region#scaled_and_snapped): this is
        a flat implementation which allows anisotropic scaling/snapping
        as well.
        And there is Layout#scale_and_snap which is a fully
        hierarchical scale-and-snap feature. The latter does not support
        anisotropic scaling/snapping, but works hierarchically without
        opening gaps. It operates on a top cell and on all layers.
  * Enhancement: new Region#pull_* methods and DRC features
        "pull_*" is a class of methods that allows rehierarchisation
        of shapes. These methods act similar to "interacting", but
        the other way around: instead of delivering interacting
        shapes of the first argument, it will deliver shapes of
        the second argument. For example, "a.pull_interacting(b)"
        will deliver polygons of b which interact with polygons
        of a. As a side effect, the polygons of b will be stored
        hierarchically close to the polygons of a. This provides
        a way to "re-hierarchise" layout.
        The full class of methods and DRC functions involve:
        Region#pull_interacting, Region#pull_inside, Region#pull_overlapping
        and the same functions for DRC.
        "pull_interacting" is also available for the Edges class
        and edge layers in DRC.
  * Enhancement: Net tracer bug fix for heavily decomposed polygons
        The net tracing feature now can operate on heavily decompose
        polygons as well. Such layouts can be created by using a low
        max. vertex count on GDS write. The problem were small
        triangles with an area of 0.5 square DBU.
  * Enhancements: General fixes of deep DRC mode
        Some inconsistencies with merged/raw mode have been
        removed. Performance was enhanced in a few places.
        Multithreaded mode now works more reliably.
  * Enhancements/bugfixes: various LVS improvements
        The backtracking algorithm should work more reliable
        in cases of ambiguities and floating nets or pins.
        Performance should be better in some cases.
        LVS script structure is less rigid now. "cheats" to
        forcibly ignore hierarchy interactions for some
        cells (useful for SRAM layout for example).
        Still there is some work to do.

        Dockable bookmark window
  * Enhancement: Hierarchical mode for DRC ("deep" keyword)
        DRC can be put into hierarchical mode with the "deep"
        statement at the beginning of the file.
        In hierarchical mode, most operations are performed
        in a hierarchical fashion - i.e. trying to maintain
        as much from the original hierarchy as possible.
  * Enhancements: Antenna checks for DRC
        DRC now got an antenna check feature. Netlist extraction
        is the basis for this feature.
  * Enhancement: Hierarchical mode in XOR tool and "strmxor"
        The XOR tool and the "strmxor" buddy tool provide
        switches to enable hierarchical mode. These options
        are considered experimental currently as XOR between
        two different layouts was not the implementation goal.
  * Enhancement: Netlist extraction
        KLayout supports extraction of netlists from a layout.
        This is the first step towards LVS. This feature includes
        an infrastructure providing netlist data structures
        (with Ruby/Python bindings), Netlist readers and writers
        (Spice format), device recognition and a netlist browser.
  * Enhancement: LVS
        The LVS feature is based on the netlist extraction capabilities.
        It adds netlist vs. netlist compare and the corresponding
        infrastructure.
        LVS is a new script environment that is based on the DRC feature
        and extends the DRC script language by LVS elements.
  * Enhancement: Command line option -mn to open netlist database
  * Enhancement: Net tracer "trace all nets"
        Based on the netlist extraction feature, an alternative mode
        for net tracing is provided. With "trace all nets", no a single
        but all nets are traced at once. Probing then happens in the
        final nets extracted rather than providing the seed shape.
        "Trace all nets" operates in hierarchical mode and therefore
        usually is faster and has a smaller memory footprint when
        extracting huge nets such as power nets.
  * Enhancement: Library browser
        The library browser is a dockable tool window which shows
        all libraries installed. Use drag and drop to place a library
        cell from the library browser in edit mode.
  * Enhancement: Layout query enhancements
        Layout queries (aka "Search and replace") now allow specification
        of Variables when using the script API. The performance of queries has been
        enhanced in the case of cell tree recursion.
  * Enhancement: Gridline colors
        The grid lines (or dots, depending on the style) can now be given
        different colors for axes, grid lines and the ruler inset.
  * Enhancement: Multiple files on import
        The "File/Import/Other files into current" feature now allows
        importing multiple files into the current layout.
  * Enhancement: Python standalone module
        KLayout supports production of standalone Python modules
        which provide the same features than the "pya" module but
        for use without the KLayout binary. If installed properly,
        "import klayout" will pull in all modules. "import \ 
klayout.db"
        will pull in the database part.
        Deployment on PyPI is supported.
  * Enhancement: Modal help dialog from modal windows
        When using Assistant links in the UI, the assistant now is shown
        as a modal window when called from a modal dialog. Before, the
        Assistant window wasn't usable in this case.
