Klayout

* Enhancement: %GITHUB%/issues/1700 Porting 2.5d view for compatibility with OpenGL 3.0 for better support on other platforms
This however comes with a larger memory footprint during rendering. Something to fix later.
* Bugfix: %GITHUB%/issues/1696 Cannot read LVS or L2N report with generic devices
* Bugfix: %GITHUB%/issues/1691 LVS soft connections: making a soft connection to a device terminal disconnects the device
* Bugfix: %GITHUB%/issues/1683 Spice reader accepts circuits without definition but pins get shorted
* Bugfix: %GITHUB%/issues/1681 Spice reader ".endl" should accept lib name
* Bugfix: %GITHUB%/issues/1679 Update sample macros for migration to Qt6
* Enhancement: %GITHUB%/issues/1678 Qt major version-wise Assistant
* Bugfix: %GITHUB%/issues/1671 Search and replace: Delete instances crashes KLayout
* Enhancement: %GITHUB%/issues/1666 'Visibility Follows Selection' option for the 2.5d view
* Bugfix: HTTPS timeout included time to enter password
So you had 10 seconds max. to enter your password :(
* Bugfix: marker and net browser windows did not get closed when clicking on close icon
* Bugfix: "duplicate interactive" now also working for rulers
* Enhancement: "upcase", "downcase" functions for expressions
* Enhancement: DRC features to reduce coding effort for certain rules
- New options for "corners": 'absolute' and 'negative' options
- New options for with/without_angle: 'absolute' option.
* Bugfixes: SPICE reader
- now detects recursive circuit calls
- skips empty top level circuit now, which did not happen when
control statements were present at top level
* Enhancements: DRC report category formation:
- "output" will add shapes to a category is the category name was
used before
- "output" accepts an array of names for the category name, creating
a sub-category hierarchy
* Enhancement: Enhanced handling of cell variants in DRC reports
Now, cell variants are listed with the original cell name and
a description of the variant formation.
* Enhancement: Marker browser enhancements and RDB API
- items can be added comment strings now.
- "info" and "save" function in marker database browser File menu
- file name shown in RDB selection drop-down
* Enhancement: DRC waiver concept
KLayout now includes a way to store waive flags along with RDB databases.
A waiver DB is nothing else than a report database file annotated with
waive flags and other attributes like comments, images etc.
For details see documentation under "DRC Basics".
New functions in marker browser:
- apply waiver DB
- save as waiver DB
* Enhancement: Editor hooks
This feature allows dynamically annotating shapes while
they are edited. This feature is somewhat experimental as of now.
See "EditorHooks" class for an example.

* Enhancement: %GITHUB%/issues/1662 Strong default grids
* Enhancement: %GITHUB%/issues/1656 Display-->Goto Position dialog should accept + as well as - for number prefixes
* Bugfix: %GITHUB%/issues/1651 Errors when adding polygons with 4 points
* Bugfix: %GITHUB%/issues/1644 DRC: some issues with edge layers
* Bugfix: %GITHUB%/issues/1643 DRC: Feeding the same layer to two-layer operations in deep mode does not render the desired result
* Enhancement: %GITHUB%/issues/1638 let klayout marker browser read strmxor .. xor.gds.gz, xor.oas result files
* Enhancement: %GITHUB%/issues/1637 XOR optimization for prBoundary layer
* Bugfix: %GITHUB%/issues/1632 rdb python/ruby module: modifing items not possible as they are const
* Enhancement: %GITHUB%/issues/1598 LVS - Support for Soft Connections

* Enhancement: New ruler type "auto measure along edge"
* Enhancement: Trigger ruler measurement on mouse hovering transiently
* Enhancement: Min and max value bounds for PCell parameters in editor
The condition is not strictly enforced - for example it is not checked when
changing parameters programmatically. For that, use "coerce_parameters".
Still, this feature is an editing aid.
* Bugfix: Pixel garbage in color selector button with "Auto" color selected
* Bugfix: DRC/LVS - connect_explicit did not accept an array of nets as single argument
* Bugfix: 'edge outside polygon' now consistently ignores the border of the polygon
* Bugfix: Warning level was ignored for some warnings in LEF/DEF reader
* Bugfix: Netlist reader: anonymous circuits are not checked for known parameters
* Enhancement: LVS - Supporting remote must-connect connections
So far, must-connect connections had to be made one level up in the hierarchy
or promoted further using labels and such. Now, must-connect connections
can be made at any point up in the hierarchy.
* Bugfix: LVS - do not waste too much time analyzing failed matches
* Enhancement: LVS - LVS: Consider net names identical that differ
in signal type suffix only - e.g. 'NET:I' is identical to 'NET'
* Enhancement: OASIS reader will produce layers that are listed in layer table
but empty. Previously, empty layers were never created, even if listed in
the layer table.
* Enhancement: Reading from HTTP streams and pipes now supports automatic .gz uncompression
* Enhancement: New DRC Features
- "edges" method allows selecting convext/concave/step edges
- Interaction count for edge/edge edge/polygon "interacting"
- Improved handling of dots (degenerated edges) - these are now
passed through the edge/edge and edge/polygon booleans and
participate in "interact". This enables selecting corners and
using them to select edges.
* Enhancement: New RBA/pya Features
- Main window title: MainWindowtitle (property)
- MainWindowsynchronous (getter added)
- LayoutViewis_dirty?
- Triangulation: Regiondelaunay
- Quality rasterizer: Regionrasterize
- Generic edge and polygon filters and operators support hierarchical processing
with Python or Ruby callbacks: classes EdgePairFilter, EdgePairOperator,
EdgePairToPolygonOperator, EdgePairToEdgeOperator, EdgeFilter, EdgeOperator,
EdgeToPolygonOperator, EdgeToEdgePairOperator, PolygonFilter, PolygonOperator
PolygonToEdgeOperator, PolygonToEdgePairOperator, TextFilter, TextOperator,
TextToPolygonOperator
Methods: EdgePairsfilter, EdgePairsfiltered, EdgePairsprocess, EdgePairsprocessed,
same for Edges, Regions and Texts
- Polygonsplit, Polygonbreak, same for DPolygon, SimplePolygon, DSimplePolygon
- Keyword arguments for Python, Ruby and Expressions
- You can now also use "klayout" package inside the application (same code
for Python module and application) - i.e. "import klayout.db"
- Synonyms: connect/disconnect for events for better compatibility with PyQt5

* Enhancement: %GITHUB%/issues/1535 Support pathlib.Path in Python API
Implicitly converts objects to strings using "str(object)" (Python) or "object.to_s" (Ruby).
* Bugfix: %GITHUB%/issues/1533 KLayout crashing with two consecutive calls of the same LayoutView::show_layout command
* Bugfix: %GITHUB%/issues/1531 When symlinking a .def to a target without .def suffix, file can't be loaded
* Enhancement: %GITHUB%/issues/1530 polygon from 2 size tuple points
The effect of this feature is pretty basic: tuples or lists are used as constructor
arguments for implicitly creating an object in place of them. Hence, "(x,y)" can be
used instead of a vector or a point. In some cases, this leads to ambiguities and
the implicit resolution will fail however.
Specifically a list of size-2 tuples can be passed to the "points" arguments of
Polygon and Path.
