As a bonus, added defaults for Box#enlarge and Box#enlarged (dx, dy)
* Bugfix: Partial mode snapping now is object first, then grid
* Bugfix: Key bindings have not been properly read from the configuration file
The change in the configuration string structure triggered an old bug:
Toolbar buttons had a twofold configuration and only the last one was
considered. Changing the order of the entries could spoil the configuration.
0.29.9 (2024-12-01):
* Bug: %GITHUB%/issues/1907 Locking layouts against modification during recursive iteration of instances and shapes
This prevents crashes in write-white-iterating scenarios
* Enhancement: %GITHUB%/issues/1923 Convenience versions of "move", "moved" on various objects
* Bug: %GITHUB%/issues/1925 Problem with import of MAGIC files
* Enhancement: %GITHUB%/issues/1934 (partial) shapes are instances are not selected when they exceed the viewport
This avoids selecting large background objects my mistake and then
moving them without noticing.
* Bug: %GITHUB%/issues/1930 Selection of structures results in thick black lines

You can turn this feature off by disabling the "Initialize other layers with default properties"
option on the techology's "General" page.
* Bugfix: More consistent handling of special paths (like data: URLs) for technology components
* Bugfix: Improve snapping in partial mode when snapping to objects
* Enhancement: Supporting "Move by" after "Clone interactive"
* Enhancement: Key bindings and menu visibility is now formatted for better readability
Now, there is one line per entry in the configuration file and the
entries are sorted with the important ones first.
* Enhancement: New export option "Copy to clipboard" in the "Search and Replace" result list
* Enhancement: Showing "select" expressions in the header row of the "Search and Replace" result list
* Enhancement: Configuration options for the transient selection markers
Now it is possible to configure transient selection differently from
static selection (line style, fill)
* Bugfix: Fixing a problem with slow transient selection in edit mode
* Enhancement: Layout#read_bytes and Layout#write_bytes
0.29.8 (2024-10-20):

* Bugfix: LEF/DEF reader recognizes existing layers by name now
This happened to be an issue if you were reloading a LEF/DEF layout as
name layers got added as duplicates.
* Bugfix: In DRC, with '@+' as target layout, maintain the original active cell view
This way, DRC can be re-run on the original layout, but each time generating a new output cellview.
0.29.7 (2024-09-22):
* Bug: %GITHUB%/issues/1864 Copy & paste allows creating a recursive hierarchy
* Bug: %GITHUB%/issues/1860 A bug about layer undo

* Bugfix: Fixed a crash in the properties editor happening while selecting object type nodes in certain cases
* Enhancement: Cleaned up and enhanced documentation of LayoutToNetlist class
* Enhancement: Less agressive polygon splitting in deep mode DRC/LVS by default
"max_area_ratio" can be a negative value now, which means that skinny diagonals
are not split into a large number of triangles. This is the default.
0.29.6 (2024-08-15):
* Bug: %GITHUB%/issues/1814 Application freezes on Ctrl+Select
* Bug: %GITHUB%/issues/1816 interacting operation between EdgePairs and Region (or edges)

* Bug: %GITHUB%/issues/1804 Instantation path highlight mismatch with view window
* Bug: %GITHUB%/issues/1768 Change "angle constraint" of box and ellipse ruler templates to "any angle" by default
* Enhancement: %GITHUB%/issues/1776 Undo/redo from List
* Enhancement: %GITHUB%/issues/1779 Marker Browser: make the state of the "By Cell" or "By Category" tree persistent
* Bug: %GITHUB%/issues/1799 Can't set cell properties by script
* Bug: %GITHUB%/issues/1794 MetaInfo with (gigantic) size makes klayout write a faulty gds
* Bug: %GITHUB%/issues/1793 inconsistent results in width_check when calling by keyword argument
* Bug: %GITHUB%/issues/1782 Internal error on "nan" values in PCells
* Enhancement: GDS2 writer now observes limitations of the file format
and raises more errors on value over- or underflows. This should specifically
avoid issues writing certain large arrays which are legal inside KLayout, but
illegal in GDS2.
* Bugfix: Small bugfix: 'Delete selected stacks' was not working from stack tech component editor's context menu
* Enhancement: Trying to improve "grab" behavior of partial selection.
In certain situations is was difficult to grab the partial selected edges.
Instead other edges would be selected. Now, it is enough to click inside the
bounding box of the partial selection.
* Bugfix: Including more GeneratorExit and StopAsyncIteration in the ignored exceptions for Python.
These exception now do not make the debugger stop any longer.
* Bugfix: Properly transferring ownership for variant to Python/Ruby translation.
This is required for some Python and Ruby bindings, when objects are
transferred through generic arrays.
* Enhancement: Added Region#being_shapes_rec and Region#begin_merged_shapes_rec.
Mainly for being able to retrieve shapes with properties from Region#nets
* Enhancement: Convenience methods Shape#properties, Layout#properties, Cell#properties, Instance#properties.
These method will obtain all properties as a hash.
* Enhancement: Added Netlist#top_circuit and Netlist#top_circuits convenience methods.
These methods will deliver the single top circuit or a list of top circuits.
* Enhancement: "Copy cells" now has an option to mute the dialog (shallow/deep)
and the dialog is only shown if there are subcells
* Enhancement: Added Shapes#break_polygons, Layout#break_polygons, Region#break_polygons.
These methods split large polygons into smaller pieces.
0.29.4 (2024-07-08):
* Bug: %GITHUB%/issues/1780 Crash on deleting multiple selected shapes or items
0.29.3 (2024-07-06):
* Bug: %GITHUB%/issues/1774 ImportError: cannot import name '__version__' from 'klayout'
* Bug: %GITHUB%/issues/1771 Python exception formatting: backtrace missing for Python >=3.11.7
* Bug: %GITHUB%/issues/1757 Fixed memory issue
* Enhancement: %GITHUB%/issues/1756 Configure timeout for HTTP(S) requests
A new environment variable has been introduced to configure the
HTTP(S) timeout: KLAYOUT_HTTP_TIMEOUT (timeout value in seconds,
default is 10s)
* Bug: %GITHUB%/issues/1769 Typo fixed
* Bug: %GITHUB%/issues/1751 Code sanity issue fixed
* Bug: %GITHUB%/issues/1750 Code sanity issue fixed

* Enhancement: %GITHUB%/issues/1655 Marker object lifetime management
* Enhancement: DRC - step-wise size with "inside" and "outside" constraint
This feature is handy for implementing latch-up rules more efficiently.
* Bugfix: OASIS reader - avoiding slight rounding of DBU In python read/write cycle (discussion-2526)
* Bugfix: Proper tracking of references of RecursiveShapeIterator.
Related to issue #1742, but not directly.
* Bugfix: Symlinks in the salt paths might have lead to macro duplication
* Bugfix: Ruby binding - "return" inside block was behaving like "break".
Now, "return" will leave the current function.
* Enhancement: LVS layer naming now also accepts an optional layer/datatype information.
* Enhancement: XOR performance enhanced in deep mode for "almost same" inputs.
* Bugfix: Macro debugger now does not prevent paint events and
screen refresh should work while debugging. In addition, the debugger
does not deadlock the desktop when using the help browser's search
function. Side effects are yet unknown - maybe debugging Qt event
handlers now becomes less stable.
Issue #1770 addresses a problem introduced during this effort and also
fixed in this release.
* Bugfix: During modal dialogs, the debugger's run/stop and step buttons were not working.
* Enhancement: DRC size/sized now also accepts sizing mode as string.
For example "layer.sized(1.um, 'square_limit')" will work now.
Previously, this argument has been ignored. This will make the GF180 DRC deck work properly.
0.29.2 (2024-06-06):
* Enhancement: %GITHUB%/issues/1724 Don't read duplicate LEF files
* Bug: %GITHUB%/issues/1722 [macOS] Crash when opening layout having Custom Macro Menus

* Enhancement: LayoutToNetlist#layer_indexes, LayoutToNetlist#layer_info (convenience)
* Enhancement: blend-mode 0 (aka AddToCell) now does not generate instance duplicates
* Bugfix: Some bug fixes on macro IDE: deleted macros do not become "zombie tabs" for example
0.29.1 (2024-05-04):
* 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: "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.
0.29.0 (2024-04-01):
* 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/1637 XOR optimization for prBoundary layer
* Bugfix: %GITHUB%/issues/1632 rdb python/ruby module: modifing items not possible as they are const

* 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: MainWindow#title (property)
- MainWindow#synchronous (getter added)
- LayoutView#is_dirty?
- Triangulation: Region#delaunay

with Python or Ruby callbacks: classes EdgePairFilter, EdgePairOperator,
EdgePairToPolygonOperator, EdgePairToEdgeOperator, EdgeFilter, EdgeOperator,
EdgeToPolygonOperator, EdgeToEdgePairOperator, PolygonFilter, PolygonOperator
PolygonToEdgeOperator, PolygonToEdgePairOperator, TextFilter, TextOperator,
TextToPolygonOperator
Methods: EdgePairs#filter, EdgePairs#filtered, EdgePairs#process, EdgePairs#processed,
same for Edges, Regions and Texts
- Polygon#split, Polygon#break, 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

* Bugfix: %GITHUB%/issues/1592 DXF file parsing error, about spline curve
* Enhancement: DRC enhancements related to touching edges
- New DRC function switches: "without_touching_corners", "without_touching_edges"
to skip width and space errors at kissing corners and touching-edge configurations
- Kissing corners are now detected also in non-collinear edge configurations
* Bugfix: fixed rendering of color selection buttons on High-DPI screens
* Bugfix: cross-hair cursor should not use selection default line width and styles
* Enhancement: OASIS reader errors out on broken OASIS with duplicate CELLNAMEs

* New binaries:
- Windows binaries now include UCRT (64 bit) and 64 bit coordinate versions
- RockyLinux 9 RPMs included
0.28.14 (2023-12-08):
* Bugfix: %GITHUB%/issues/1563 Duplicated Tabs in the Macro Development Tool
* Bugfix: %GITHUB%/issues/1560 git+https package installation on windows fails
* Bugfix: %GITHUB%/issues/1559 (partial) Move function not respecting some diagonals

* 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.
* Enhancement: %GITHUB%/issues/1528 LEF: Implement LEF58_WIDTHTABLE
* Enhancement: new methods (D)Edge#euclidian_distance and (D)EdgePair#distance
* Bugfix: package download dialog: mute an assertion, less questions for re-running macros
* Enhancement: reading $KLAYOUT_GIT_PROXY_HTTP for proxy URL in Git downloads
* Bugfix: cheats were not enabled for edges and (implicit) polygon merges such as for "sized"

* Enhancement: %GITHUB%/issues/1307 (partial) Produce UNPLACED macros if location is provided
* Enhancement: New aliases for inline operators (e.g. "+=") in RBA::Region and similar classes
Reasoning is that "+=" in Ruby is resolved into "+" and "=" which does not make
use of the inline optimization. Using "join_with" instead will avoid this. Other alias:
"join" for "+", "and" for "&", "and_with" for "&=", "not" for "-", "not_with" for "-=",
"or" for "|", "or_with" for "|=", "xor" for "^" and "xor_with" for "^=".

ends if edges overlap, graphical indicator for selected partial
- Wheel events do no longer change Combo Box selections
- DRC/LVS: log output overhead reduced for faster execution in
small layout cases
- Added RBA::Image/pya.Image constructor taking QImage and PixelBuffer
- Point objects are native citizens now of the database and act as
representatives for handles, better editing and visualization of
the latter
- Macro editor has "find previous" button now
- Mitigate the effect of overriding a globally-defined technology
with -nn on the command line by creating tech variants
- LEF/DEF map files now allow LEFPINNAME and PINNAME purpose to

- Meta information can be attached to layout and cells
- Meta information has a string key and arbitrary value (hash, list supported)
- Optionally, meta information can be made persistent and
is stored in the (KLayout specific) context section of GDS2 and OASIS
- Meta information is shown in the user properties dialog, but is not editable

0.27.8 (2022-02-13):
* Bugfix: %GITHUB%/issues/971 Double compare fails in LVS
* Bugfix: %GITHUB%/issues/972 CIF writer generates unreadable file with invalid cell or layer names

* Bugfix: reverted change of #796
DXF version is back to AC1006 which seems to be more compatible with most consumers of
DXF files. Using 1016 AC1014 seems to require much more meta information I cannot
provide without deeper insight into the DXF structure.
0.27.2 (2021-06-20):
* Enhancement: %GITHUB%/issues/818 2.5d view shows view area instead of full layout
This way, it's possible to confine the extruded view to a small area of the
layout easily.
* Bugfix: %GITHUB%/issues/824 LEF/DEF flow - duplicate text label generated

A new keyword ("padding_ignore") can be added to with_density/without_density
to ignore parts outside the boundary instead of treating them as zero
density.
* Enhancement: %GITHUB%/issues/808
Feature suggestion: DRC to report edges attached to corners as edge pairs.
There is a new output mode "as_edge_pairs" in addition to "as_dots" and
"as_boxes" now.
* Bugfix: %GITHUB%/issues/807 DRC: clear_connections and incremental connect was not working.
This is an important feature for correctly implementing antenna checks
* Bugfix: %GITHUB%/issues/806 LVS: CustomComparer is not working
* Bugfix: %GITHUB%/issues/801 DRC Layer#smoothed lacks the "keep_hv" argument

A problem with memory corruption in certain scenarios was causes
an application crash.
* Bugfix: %GITHUB%/issues/778 Use system font instead of hard coded "Monospace"
* Bugfix: DRC "flatten" did not always flatten, but kept layers hierarchically
* Enhancement: DRC: a couple of new filters on edge pair layers:
- with_angle/without_angle: filter by angle of the edges (one or both)
- with_length/without_length: filter by length of the edges (one or both)
- with_distance/without_distance: filter by distance of the edges
* Enhancement: Added Edge#cut_point method
* Enhancement: LEF macro layouts now can be specified in UI
* Bugfix: full_edge, negative output for fragmented polygon vs. small ones (space, enclosure, overlap).
In some cases, only parts of the edges were reported and negative output was
incorrect. In addition, negative output for two-layer checks - such as "l1.drc(sep(l2) > 0.2)" - now
only is produced for the primary layer. With both outputs it was difficult to separate the
components.
* Bugfix: computed layers were printed with layer properties in lvsdb files sometimes.
* Enhancement: Performance improvements and memory footprint reduction for OpenRAM test case
* Bugfix: a number of typos fixed and documentation clarifications
* Bugfix: DRC "or" was producing flat output in deep mode
