* Use Qt 5 instead of Qt 4 Changelog: 0.25.3 (2018-05-03): * Enhancement: Compile option to use libcurl instead of QtNetwork This workaround enables builds on the native CentOS6 configuration with the package manager functional. * Enhancement: Pass label (text) layers through DRC script The "labels" method now allows copying labels from a layer to the output. * Enhancement: New "split" method for polygons This method will fragment the polygons into two or more smaller parts for reducing their vertex count. * Enhancement: New "dtrans" method for RecursiveShapeIterator This method delivers the transformation in micron unit space * Enhancement: New "insert" methods for Shapes Shapes can now insert from another Shapes container and from a RecursiveShapeIterator. Possible applications are fast flattening and fast region selection. * Enhancement: New method to generate RDB items from shapes RdbItem#add_value from a shape, RdbDatabase#create_items from a shapes container or recursive shape iterator and RdbDatabase#create_item from a shape. * Enhancement: DXF and CIF "keep layer names" If this option is set in the reader options, layer names are not translated into GDS layer/datatype pairs. Specifically a layer called "L5" for example is not translated to 5/0 and to "L5D0" on output correspondingly. The buddy script option is "--keep-layer-names". * Enhancement: DXF contour joining accuracy On the DXF reader's options, a contour joining accuracy can be specified. Small gaps smaller than this accuracy will be closed when forming joined contours from edges. The buddy script option is --dxf-contour-accuracy=value. * Bugfix: DXF display issue In some cases, DXF cell instances did not trigger bounding box update and the cells only got visible after save and load. * Bugfix: XOR progress is more realistic The progress is updated after the layer has been computed, not before. * Bugfix: KLayout/klayout#117 DTrans#itype was broken. * Bugfix: KLayout/klayout#116 Fixed a polygon decomposition bug when writing GDS files with big polygons with many holes. As a side effect, the polygons with many holes computed by a NOT operation for example are less complex and spikes in the cutlines are avoided. * Bugfix: KLayout/klayout#115 Reader options were not persisted. * Bugfix: KLayout/klayout#114 Custom line styles not loaded from tech's layer properties file. * Enhancement: KLayout/klayout#113 The XOR tool has an option now to heal result shapes which cross tile boundaries. The result shape count of tiled and non-tiled mode should basically be the same then. * Bugfix: KLayout/klayout#112 Salt package repository relative paths have not been working. * Bugfix: KLayout/klayout#109 Issues with Python 3 and shape properties - property * Bugfix: KLayout/klayout#108 Bugfix on Box#enlarge and Box#moved for empty boxes. keys generated with Python 3 could not be written to GDS2. * Bugfix: KLayout/klayout#107 Undo not working with shapes. * Enhancement: KLayout/klayout#106 Search & replace help page enhancements. 0.25.2 (2018-03-20): * Bugfix: KLayout/klayout#90 DRC: "extended" was not working as expected with "joined = true" * Bugfix: KLayout/klayout#89 Display issue on MacOS fixed * Enhancement: KLayout/klayout#85 IDE debugger: files can be excluded from showing exceptions when they are thrown. To exclude a file press the new "Ignore" button when the debugger tells you an exception has been generated. To re-able exception reporting, clear the list of the files in the IDE settings ("Debugging" tab) The macro IDE settings can now be edited in the File/Setup dialog. * Bugfix: KLayout/klayout#94 Retina displays are support to some extend on MacOS. An open topic is the quality of the icons. * Enhancement: build system for MacOS 0.25.1 (2018-02-23): * Enhancements: build compatibility with MacOS and Qt 5.9. Qt 4.6 supported now as well with one restriction: the package installation feature is not working. * Bugfixs: Package manager - Remove button wasn't enabled if multiple packages were selected - A potential crash ob removing packages was fixed * Enhancement: 64 bit coordinate support enabled on Windows builds * Further bugfixes: See links - KLayout/klayout#21 (Autorun(-early) doesn't seem to run when lym files are inside a package) - KLayout/klayout#24 (Text insert dialog bug - Ok button isn't working) - KLayout/klayout#26 (Exceptions are reported every time they propagate up in the call chain in the ruby debugger) - KLayout/klayout#28 (CIF format detection failed) - KLayout/klayout#30 (Writer options dialog non-functional on a fresh configuration) - KLayout/klayout#32 (Rounding issue with instance properties) - KLayout/klayout#33 (Plugin factory not working when using with Python) - KLayout/klayout#36 (Hardening against destruction of object inside event handler) - KLayout/klayout#39 (Action cannot be reassigned) - KLayout/klayout#40 (Crash in Python binding) - KLayout/klayout#41 (Polygon#touches? issue) - KLayout/klayout#42 (Headless mode support with Qt5/-zz) - KLayout/klayout#43 (Crash when using Qt specific command line options) - KLayout/klayout#44 (Transformation constructor with x,y not working) - KLayout/klayout#45 (Partial selection does not capture instance) - KLayout/klayout#48 (Cancel does not reset current tool) - KLayout/klayout#51 (Segmentation fault on return to main window and other opportunities) - KLayout/klayout#53 (Unreadable 'about' text) - KLayout/klayout#62 (QXmlSimpleReader#parse cannot be called) - KLayout/klayout#63 (Wrong output on DRC non_interacting with empty second input) - KLayout/klayout#64 (Crash on exit) - KLayout/klayout#68 (OASIS reader issue with degenerated shapes) - KLayout/klayout#69 (DRC: 'inside' does not merge shapes of second input) - KLayout/klayout#71 (Target cell argument is required) - KLayout/klayout#72 (Edges/Region NOT issue) - KLayout/klayout#73 (Allow 'change layers' on PCells which support a single layer parameter) - KLayout/klayout#74 (Small-corner boolean issue) - KLayout/klayout#75 (Python PCell issue when parameters are called 'layer') - KLayout/klayout#79 (Replace function enabled also for read-only macros) * Further enhancements: see links - KLayout/klayout#29 (Permissive mode for OASIS writer on odd-width paths) - KLayout/klayout#59 (Async download of package index and details) - KLayout/klayout#66 (Authentication dialog indicates retry) - KLayout/klayout#77 (Layout#copy_tree now works in non-editable mode too) 0.25 (2017-11-04): * Enhancement: Menu customization Menu items can be disabled or enabled now. The former "Key Bindings" configuration page has been turned into "Menu Customization". Check boxes allow enabling or disabling of menu items. Disabled menu items are not shown. A search filter allows quick selection of menu items by title or path. * Enhancement: The cell tree no longer is collapsed on edits or when the sorting order changes. * Enhancement: Using a special menu path, macros can be configured to appear in submenus now. * Enhancement: KLAYOUT_HOME environment variable to control the location of the application folder.

These buttons jump to the previous or next display state: zoom window, hierarchy depth, etc.. * Enhancements: A Package manager is provided. Packages are add-ons for KLayout and can include macros, script libraries, fonts for the TEXT PCell, technologies, DRC scripts etc. Packages can be published on GitHub or any server supporting WebDAV. After registering a package, users can install or update packages with a few clicks. For more information see https://github.com/klayoutmatthias/klayout/wiki or "About Packages" in the "Various Topics" area of the main documentation. The package manager is found in the "Tools" menu under "Manage Packages". * Enhancements: LEF/DEF reader: - Compatibility fixes with version 5.8 - Regions and Groups are supported now - LEF/DEF is a standare format now and can be used with "File/Open" for example. * Enhancement: DXR reader supports variable path widths now * Enhancement: XOR provides graphical progress * Enhancements: Libraries can be associated with a technology.
