0.27 (2021-05-02):
* Enhancements: Numerous new functions for the RBA and pya API
Some highlights:
* "Texts" for text collections (similar for Edges/EdgePairs/Region)
* New modes for blending layout files - see GitHub issue #666
* New function Cell#transform - see GitHub issue #598
* New functions for Image (read, write, clear)
* New functions for Region and Edges correlating with the new DRC features
* Multi-cell hierarchical copy/move of trees - will maintain shared instances
* RBA: iterators are now automatically made available as Enumerable
* All functions having a void return specification now return self (allows chaining)
* More functions for manipulating selections (LayoutView#select_all etc.)
* 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)
* Snap highlighting
* Mouse tracking cursor indicates grid- and object-snapped location
* Enhancements: Help browser
* Bookmarks
* Search in page (Ctrl+F)
* 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.
