Previous PKGREVISION did not install plugins, so that reading file may give
unsupportted format error etc. Installing more files now. Because of this
the directory is now under ${PREFIX}/lib/klayout/. The error was originally
reported from Atsushi Toyokura by personal communication, thanks.
(The problem was since 26.*, probably), PKGREVISION++.
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)".

- $(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.
* Enhancement: %GITHUB%/issues/353

* 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.

* Enhancement: %GITHUB%/issues/343
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.

Install the new interchangeable BLAS system created by Thomas Orgis,
currently supporting Netlib BLAS/LAPACK, OpenBLAS, cblas, lapacke, and
Apple's Accelerate.framework. This system allows the user to select any
BLAS implementation without modifying packages or using package options, by
setting PKGSRC_BLAS_TYPES in mk.conf. See mk/blas.buildlink3.mk for details.
This commit should not alter behavior of existing packages as the system
defaults to Netlib BLAS/LAPACK, which until now has been the only supported
implementation.
Details:
Add new mk/blas.buildlink3.mk for inclusion in dependent packages
Install compatible Netlib math/blas and math/lapack packages

### Version 1.6 (Aug 12, 2020)
* Added support for element properties.
* Added transformation support to `Cell.copy`.
* Layer/datatype filtering in `get_polygons` for `Cell`, `CellReference` and `CellArray`.
* Layer/datatype filtering in `LayoutViewer`.
* Removed global cache `_bounding_boxes`. Only cells cache their bounding boxes.
* Bug fixes (thanks Daniel Hwang for the contributions).
* Bug fix in `Cell.copy` where the whole dependency tree would be copied on a deep copy creation.
These packages are susceptible to bugs when confronted with non-ASCII
characters.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94182.
It takes some time to analyze and fix these individually, therefore they
are only marked as "needs work".
Version 1.5.2 (Feb 01, 2020)
Added support for importing GDSII files containing BOX elements.
Bug fix in GdsLibrary.extract (thanks collineps for finding the problem).
Version 1.5 (Dec 20, 2019)
New Cell.write_svg function to export an SVG image of the cell.
New GdsLibrary.new_cell function to quickly create and add cells to a library.
GdsLibrary.add can update references when a cell is overwritten.
Added GdsLibrary.remove to allow cells to be properly removed from libraries.
Added GdsLibrary.rename_cell to rename cells in libraries.
Added GdsLibrary.replace_references to easily replace referenced cells in libraries.
GdsLibrary.add can add dependencies recursively.
Iterating over GdsLibrary objects yields all its cells.
Iterating over Cell objects yield all its polygons, paths, labels and references.
Breaking change to *.to_gds functions in order to improve write efficiency (this should not be a problem for most users, since gdspy.write_gds and Cell.write_gds remain the same).
Breaking change: renamed GdsLibrary.cell_dict to GdsLibrary.cells.
Deprecated: gdspy.current_library, gdspy.write_gds, gdspy.fast_boolen, GdsLibrary.extract.
Bug fixes and better tests for FlexPath and RobustPath.
Version 1.4.3 (Nov 11, 2019)
Bug fix for FlexPath and RobustPath references.
Version 1.4.2 (Oct 01, 2019)
Bug fix in FlexPath.

Bug fixes (thanks to DerekK88 and Sequencer for the patches).
Version 1.4 (May 18, 2019)
Revised documentation.
New FlexPath and RobustPath classes: more efficient path generation when using the original GDSII path specification.
New Curve class: SVG-like polygon creation.
Added PolygonSet.mirror (thanks to Daan Waardenburg for the contribution).
Added Path.bezier to create paths based on Bézier curves.
Added Path.smooth to create paths based on smooth interpolating curves.
Added get_gds_units to get units used in a GDSII file without loading.
Added get_binary_cells to load only the binary GDSII representation of cell from a file.
Added argument tolerance to Round, Path.arc, Path.turn, and Path.parametric to automatically control the number of points in the final polygons.
Added argument binary_cells to GDSII writing functions to support get_binary_cells.
Added argument rename_template to GdsLibrary.read_gds for flexible cell renaming (thanks to @yoshi74ls181 for the contribution).
Changed return value of slice to avoid creating empty PolygonSet.
Added argument timestamp to GDSII writing functions.
Improved Round to support creating ellipses.
Added support for unlimited number of points per polygon.
Added support for BGNEXTN and ENDEXTN when reading a GDSII file.
Polygon creation warnings are now controlled by poly_warnings.
Incorrect anchor in Label now raises an error, instead of emitting a warning.
Added correct support for radius in PolygonSet.fillet on a per-vertex basis.
Speed improvements in GDSII file generation (thanks to @fbeutel for the contribution) and geometry creation.
Font rendering example using matplotlib (thanks Hernan Pastoriza for the contribution).
Expanded test suite.
Version 1.3.2 (Mar 14, 2019)
Small fix for building on Mac OS X Mojave.
One is via "${JAVA_BINPREFIX}-java", and one is via
"${PKG_JAVA_HOME}/bin/java".
The "${JAVA_BINPREFIX}-java" way relies on an appropriately named
executable being present in the built-in JRE if you are using the
built-in - something with a "-java" suffix. That just doesn't exist
in either the MacOS Oracle JRE install or the JDK install. So switch
to "${PKG_JAVA_HOME}/bin/java" instead, which works (but does require
careful quoting to allow for spaces under MacOS).
Bump PKGREVISION.
