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

Previously, a check like "layer.drc(width == something)" was not flagging
all candidates correctly.
* Enhancement: A PCell can request "lazy evaluation" now
This means that a parameter change needs to be committed in the UI before
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
* Bugfix: less liberal evaluation of expressions in string to numeric conversion

* 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

of the package repository at sami.klayout.org.
* Enhancement: a lot of typos fixed in documentation and code (thanks to Eugene)
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
* Enhancement: %GITHUB%/issues/798 More flexibility on Spice reader.

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

- 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)

* Enhancement: Improved fill tool.
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
Difficult to select specific labels for net name assignment in net extraction.

Crash on LayoutView#clear_selection on Linux.
* Bugfix: %GITHUB%/issues/723
Backup scheme wasn't working correctly with a single file without path
given as command line argument.
0.26.10 (2020-02-02):
* Enhancement: %GITHUB%/issues/720
"Safe save" and backups: when saving files, the file is only overwritten after
the save terminated successfully. This will avoid loss of data for full volumes
or network share dropouts. In addition, a configurable number of back files can
be kept (see File/Setup: Application/General).
* Bugfix: %GITHUB%/issues/718
GDS export issue fixed (breaking of polygons was filling holes)

* Bugfix: HTTP stream reading issue with redirect
At least on MacOS a segfault happened when reading HTTP stream data
(e.g. for package manager) from addresses which are redirected.
* Enhancement: Removed %APPDATA% from DLL search path on Windows
This will avoid installation poisoning by the one from %APPDATA%
(which ironically is the default installation path). Eventually
multiple versions can be used in parallel.
0.26.9 (2020-11-27):
* Bugfix: %GITHUB%/issues/658
Menu items were not put into the right place on MacOS.
* Bugfix: %GITHUB%/issues/652

Cell placements with small magnification factors (such that the
viewport dimensions exceeded the DBU space when seem from inside
the cell) lead to display errors.
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)".

* 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):

* 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.
