What's new in this version:
Enhancement:
- "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.
- 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.
- More flexibility on Spice reader A number of new features has been provided for the spice reader delegate
- 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
- Added Edge#cut_point method
- LEF macro layouts now can be specified in UI
- Performance improvements and memory footprint reduction for OpenRAM test case
Fixed:
- DRC: clear_connections and incremental connect was not working This is an important feature for correctly implementing antenna checks
- LVS: CustomComparer is not working
- DRC Layer#smoothed lacks the "keep_hv" argument
- Unstable application with verbose log output
- Bug on each_image_selected
- Query issue (or general: expression issue) A problem with memory corruption in certain scenarios was causes an application crash.
- Use system font instead of hard coded "Monospace"
- DRC "flatten" did not always flatten, but kept layers hierarchically
- 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.
- computed layers were printed with layer properties in lvsdb files sometimes.
- a number of typos fixed and documentation clarifications
- DRC "or" was producing flat output in deep mode

What's new in this version:
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.
Fixed:
- Fixed an issue with QByteArray/QVariant transformation in Qt binding
- PCB gerber import: Incorrect handling of D02 operations.
- Proper handling of comments in RVE DB reader
- Bug in the "smooth" function
- Deep mode DRC: separation from "inside" gives wrong errors
- Internal error on net extraction
Enhancement:
- LVS could not do "connect_implicit" with global nets
- Plain transformation of cell missing
- RBA/PYA: Provide event when a net is selected in the netlist browser
- True support for text objects in DRC/LVS (text layers)
- Edges#extents, Texts#extents and EdgePairs#extents now work hierarchically in deep mode. In DRC, this means, "extents" is a deep-enabled method now
- Image handling enhancements
- Enhanced API for ObjectInstPath
- Difficult to select specific labels for net name assignment in net extraction. Solution involves a more elaborate handling of texts through "text layers
- A separate search range can be specified for box selections now
- Technology specific libraries: library name resolution based on technology
- Controlling the way a layout reader integrates cells into an existing layout
