0.27.7 (2022-01-12):
* Bugfix: %GITHUB%/issues/969 PCell error (infinite recursion)
0.27.6 (2022-01-04):
* Enhancement: %GITHUB%/issues/963 Display snapped position in main window
* Bugfix: %GITHUB%/issues/960 Cap values range now shown in netlist browser
* Bugfix: %GITHUB%/issues/954 Fixed a device extraction glitch
* Bugfix: %GITHUB%/issues/951 Internal error fixed when deleting the cell you're sitting at
Side effect: copy & paste of cells is correctly disabled now in viewer mode
* Bugfix: %GITHUB%/issues/942 Technology file routing suffix string typo
* Bugfix: %GITHUB%/issues/946 Python: __file__ returns quoted path string
* Bugfix: DRC check for equal width now returns more consistent results
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
This will fix a potential vulnerability which allows someone to sneak
in expression code through malicious configuration, technology or layer properties
files.
XXXTNN package phase is broken on macOS due to app bundling changes.
Extensive CMake surgery required. Will fix this in a follow-up commit.

Despite not causing a failure to build and package, qcad's build was
failing to find libqcadcore while building libqcadscripts. This
commits adds a patch, similar to many others already present, that
adds -L ../core and then installs the library (and then the expected
PLIST change).
It remains a mystery why the build ever worked; the makefile I get
seems to ignore the failed build, which seems wrong. The bulk builds
have worked. But Mustafa reports a build failure, and I find that
failure in my log, even if it is non-fatal.
Reported by Mustafa Dogan.
3.3.111 01sep21 Fix in fstapi for read start limit time.

* 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

* 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

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

- more PLIST_SUBST
(upstream changes)
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: 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
"M" factor scaling was not working for Spice reader.
* Bugfix: %GITHUB%/issues/651

Text orientation was not considered properly in search & replace
* Bugfix: %GITHUB%/issues/646
A potential crash was fixed happening when a PCell
library is deleted
* Bugfix: Display bug
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.
"More than 280 commits since 2.2.0-rc1 and too much delay, but here it is,
the next big step to final 2.2.0 release. We fixed some really serious
bugs with DWG reading, what hopefully leads to much less issues and crashes
when opening DWG files. There may be still some issues with DWG we want to
address and fix for the final 2.2.0 release."
