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)
EdgePair layers in DRC can now tested for interacting with edges and polygons
(includes: inside, outside). New methods for EdgePairs: EdgePairs#inside etc.
* Bug: %GITHUB%/issues/1819 Discrete soft small rendering
* Bug: %GITHUB%/issues/1823 "Select all" was not working as expected for texts, API "select_all" was not working at all.
* Bugfix: Typo: ParameterState#icon was named 'tooltip'
* Enhancement: Allowing RBA::Net objects for DRCLayer#nets as well
* Enhancement: const versions of Layout#cell and Layout#top_cell(s)
* Enhancement: Generic GSI method and #_const_cast to make a const
reference into a non-const one (use with care)
* Bugfix: 'netter' function in DRC wasn't working as described - it raised an error
* Enhancement: Provide a warning message when closing the window while an operation is ongoing
* Bugfix: Avoid a segfault in the property editor due to invalid array access
* Bugfix: Properties dialog: stop handling 'Enter' key - use 'Ok' to close it
* Enhancement: Some improvements on Ascend and Descend:
- Ascend now walks up the unspecific tree too
- Descend enters cell if selected transiently
- New feature "Descend into" which also selects the child cell
as current top
0.29.5 (2024-07-30):
* Bug: %GITHUB%/issues/1784 Spice throws error at midline semicolon comments
* Enhancement: %GITHUB%/issues/1790 Support for recursive PCell instances
* 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/1747 Transformations on negative floats/ints
* Bug: %GITHUB%/issues/1743 strmxor shows no difference, klayout xor shows 85
* Enhancement: %GITHUB%/issues/1741 Tooltip strings for PCell parameters
* Bug: %GITHUB%/issues/1733 Instance selecion in object properties does not match with view port object highlight
* 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: %GITHUB%/issues/1721 Feature request: send results from a query to selection
* Enhancement: %GITHUB%/issues/1719 Small LVS issues
* Enhancement: %GITHUB%/issues/1710 Feature request: create separate cell for def FILL
* Bug: %GITHUB%/issues/1709 Problem displaying multiple text labels with same x value
* Bug: %GITHUB%/issues/1706 [macOS] User Properties Dialog Crashes
* Enhancement: %GITHUB%/issues/1701 Feature request: strm2oas should report input unit differences
* Enhancement: Methods to obtain representative shapes of subcircuit pin and terminals, i.e.
LayoutToNetlist#shapes_of_pin, LayoutToNetlist#shapes_of_terminal.
* Enhancement: Some enhancements in the Ruby/Python area like better messages in case
of argument mismatch errors and better handling of default values for enum arguments.
* 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.

* 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/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: 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

* Enhancement: LVS - LVS: Consider net names identical that differ
in signal type suffix only - e.g. 'NET:I' is identical to 'NET'

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.

- 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/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.

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 "^=".

This layer is available with the same style and configuration than the guiding shape layer.
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

it is being taken. This way, slow PCell evaluation will not make the
application stall. To add this feature, reimplement "wants_lazy_evaluation"
in the PCell class to return "true".
* Enhancement: "lvs_data" is a global function now in LVS scripts

* Enhancement: Ruby 3.0 basic enabling
* Enhancement: DRC "extent" accepts a cell name pattern now to deliver cell bounding boxes
* 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
* Bugfix: %GITHUB%/issues/826 Crash on deep, threaded DRC mode with universal DRC function
* Bugfix: %GITHUB%/issues/835 Crash on layout save after deep copy + close of other
* Bugfix: %GITHUB%/issues/839 Crash after PCell code exception is handled in Macro IDE

0.27.1 (2021-05-31):
* Enhancement: %GITHUB%/issues/809
"without_density" goes outside the boundary of the input layer.
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

- Spline interpolation code available in new "Utils" namespace
- QByteArray support, mapping to Python byte arrays
- MainWindow#set_key_bindings, MainWindow#get_key_bindings, MainWindow#set_menu_items_hidden etc.
- New class RecursiveInstanceIterator (similar to RecursiveShapeIterator, but acts on instances)
- Deep vs. flat operations do not always flatten out now (flat vs. deep does however)
- Global transformations for inputs
* Enhancements: New DRC features.
Some highlights:
- Better support for texts - "text layers"
- Combined AND+NOT feature for separating regions into inside and outside part
- "max_vertex_count" and "max_area_ratio" configuration options
- "forget" for memory optimization
- Shielding is optional now for some DRC functions
- "interact" now has a count filter
- In verbose more, figure counts and more information is printed
- Generic DRC function and complex DRC operations: for details search "Universal DRC" in documentation
- "not_opposite" and "rect_filter" options for some DRC functions
- "enclosing" (selects polygons entirely enclosing others)
- New filters for polygons: squares, non_squares, area ratio, bbox aspect ratio
- More intuitive specification of projection limits ("projecting < 2.um")
- "with_holes" and "without_holes", also with count
- Density check is included now ("with_densitiy", "without_density")
- "split_..." functions give interacting/non-interacting sets in one step
- Better support for generic transformations as Matrix2d and Matrix3d
- "fill" and "fill_with_left" functions for dummy fill
- NO "connected" feature yet. Sorry. Had to drop it to finish this release.
* Enhancements: new LVS features.
Some highlights:
- Improved netlist and LVS result browser (infinite-depth browsing)
- Improved circuit match algorithm
- Case insensitive handling of object names for SPICE netlists
- Probe feature fixed in flat mode
- "connect_explicit": for details search "connect_explicit" in documentation
* Enhancements: New features for images.
Some highlights:
- New menu item: show and hide all images - see GitHub issue #535
- False color nodes now can have a left and right color allowing color steps
- Persistance of images through a special file format: "lyimg" (XML based)
* Enhancements: LEF/DEF reader.
Some highlights:
- Support for layer map files
- More complete spec support (e.g. FILL, MASK, FOREIGN, DO/BY/STEP ...)
- Several bug fixes, e.g. routing layer switch for VIAs
- Some functions also act on the transient selection (less mouse clicks)
* Enhancements: Layout editing and rulers.
Some highlights:
- Object properties now are changed without having to commit the dialogs
- Dockable editor options windows
- "Recently used" list
- A "distribute objects" feature (Edit/Selection/Distribute)

The fill tool now also supports skewed fill pattern repetitions
* Enhancement: Ability to utilize a LayoutView as a Widget.
Standalone instantiation of a LayoutView object is
supported now. So it becomes possible to create
custom MainWindow UIs and embed a layout view there.
* Enhancement: Improved layer and cell list filtering and searching
* Enhancement: Experimental 3d (called 2.5d) view of layout.
For details search "2.5d View" in documentation.
* Enhancement: Improved performance on sea of instances for OASIS files.
Iterated OASIS instances are stored and handled in a leaner way in viewer mode
* Enhancement: Buddy scripts can concatenate files with "+" for input.
Concatenation happens by "blending files". Beware of the risk this implies.
A new option "--blend-mode" has been introduced for supporting overwrite, skip
and variant formation in case of cell name conflicts. See buddy script help.
* Enhancement: Layer maps now support n:m layer mapping.
This allows mapping n input layers to one logical layer (merging) and also
one input layer to m logical ones (clone layer). This applies to the
buddy scripts and layer maps inside KLayout's reader.
* Enhancement: include mechanism for easy include of files into DRC/LVS scripts.
This is a plain text substitution feature. Don't use it for Ruby or Python
scripts (the preferred way is still require/import). But it's a quick way
to include partial DRC and LVS scripts without having to worry about variable
scope. For details see "Including other files" in the documentation under:
KLayout User Manual/Design Rule Check (DRC)/DRC Runsets.

Image handling enhancements.
* Enhancement: %GITHUB%/issues/521
Enhanced API for ObjectInstPath.
* Enhancement: %GITHUB%/issues/487
