- Update to 0.24.9

* Enhancements: The RBA::Region#smooth function was enhanced to 
       give somewhat better results
* Enhancements: DXF's circle approximation can now also specified 
       through an "accuracy" parameter: if less than the number of 
       specified points is required to achieve the given accuracy, the
       number is reduced accordingly. This also applies to the polygon
       interpolation of spline and arc curves.
* Enhancement: RBA integration now is compatible with Ruby 2.3 
       which allows building on Ubuntu 16 as well.
* Enhancement: OASIS files with instance angles >360 were rejected
       before. Now, this has turned into a warning.
* Bugfix: DEF reader was failing to read MASK/via combinations.
* Bugfix: The marker browser's "show only rules with errors" option
       was enabled again on sorting of errors.
* Bugfix: Using Layout objects for inputs didn't work
* Bugfix: Copying Hierarchy treets containing PCell's made the 
       PCell's being turned into static cells.

- Update to 0.24.8

* Bugfix: XOR and different or big database units:
       With tiling, XOR between two layouts with different database
       units was still not working correctly. Also, when the database unit
       was larger than 1nm, the XOR feature was dropping results sometimes
       when tiling was on.
* Enhancements: progress bar shown also for "-z" mode scripts:
       The solution of 0.24.7 has been modified to avoid annoying
       progress bar windows popping up in background-window mode:
       Now, progress bar windows will only pop up if an active main
       window is present. This will enable progress bars for scripts that
       open their own main windows but still keep the application GUI-less
       when the script does not do so.
* Bugfix: Crash on empty panel:
       When "New/Panel" is used a view without a layout is created.
       An attempt to create layout on such panels crashed the application.
* Bugfix: LEF reader now can read PIN statements including VIA
* Bugfix: Polygon smoothing was not working properly in some cases
       Previously the smoothing function was sometimes dropping vertexes
       from the polygons.
       Smoothing now does also guarantee not to exceed the given 
       distance.
* Bugfix: Sorting cells by area now sorts cells by name as second choice
       In the previous version, cells with identical area were 
       grouped but the order was arbitrary. Now the name is used as
       the second-level sorting criterion which keeps such cells
       sorted by name.

Sat Apr 30 22:08:22 UTC 2016 - matthias@koefferlein.de

- Update to 0.24.7

* Bugfix: XOR and different database units:
       With tiling, XOR between two layouts with different database
       units was not working correctly.
* Enhancements: progress bar shown also for "-z" mode scripts:
       Scripts running in KLayout with the "-z" option (don't
       show main window) were not experiencing progress reporting
       before. Now a small modal window is shown during long-running
       operations that indicates the progress and provides a Cancel
       button to abort the operation.
* Bugfix: Crash on using "Edit/Make cell":
       This happened sometimes if the selected objects contained
       instances.
* Bugfix: Invalid behavior of paths with reflecting segments:
       For example a path made of the points (0, 0), (0, 1000)
       and (0, 0) had a reflecting segment which cause some 
       computations (for example the bounding box) to return
       invalid results.

-------------------------------------------------------------------

- Update to 0.24.6

* Bugfix: Early delete of plugin object when returning a new object
       from PluginFactory#create_plugin. The returned object was 
       not held, so in Ruby the GC could destroy the object. This 
       could lead to crashes in applications employing the Plugin API.
* Bugfix: It was possible to edit read-only macros. 
       For example, it was possible to enter new lines in macros 
       marked as read-only. However, these changes were not saved.
* Bugfix: Shift+Tab not working in macro editor. 
       On some platforms, Shift+Tab was not working as expected. 
       This key combinations was supposed to left-shift a selected
       block an undo indents.
* Bugfix: Wrong scaling of layers when doing XOR's with layouts
       with different database units.
       This happened when the layouts had different layers and 
       "summarize missing layers" was disabled.
* Bugfix: "Search & Replace" was not working properly if named 
       layers were present. Specifically the shape search was not
       working due to an incorrectly formed query.       
* Bugfix: Sizing produced incorrect results in case of slowly
       varying polygon contours. The effect was a contour with 
       spiky distortions where two "almost parallel" edges 
       connected.
* Bugfix: The diff tool was not reporting differences correctly when
       layers were present in one layout while they were not present
       in the other. This happened specficially when "Summarize 
       missing layers" was disabled.
* Enhancement: New context mode in marker browser: "Current or Any".
       In this mode, the markers are displayed in the context of the
       current cell. If that is not possible because the markers are
       given for cells outside the cell tree of the current cell, the
       fallback is to show the markers in the current cell as in "Any"
       mode.
* Enhancement: More consistent behaviour of cell and category filters
       in the marker browser. For example, the category filter is 
       now also applied when selecting a node for a certain cell in 
       the cell branch and if nested categories are present, the 
       category filter is applied smarter - not just on each category.

-------------------------------------------------------------------

- Update to 0.24.5

* Bugfix: Instance browser was messing up array instances sometimes.
       After browsing instances, in some cases array instances got
       messed up. This specifically happened with OASIS files.
* Enhancement: Diff tool does not care about text alignment and
       font properties unless in "exact" mode. Previously alignment
       flags and font properties were compared in non-exact mode too
       causing some confusion for example when comparing OASIS vs. 
       GDS.
* Enhancement: XOR on layouts with different database units.
       Previously, the XOR tool refused to run on layouts with
       different database units.
* Bugfix: The OASIS writer's S_TOP_CELL standard property now will 
       correctly use an "n-string" value in strict mode.
* Bugfix: The OASIS writer bailed out on 1x1 cell arrays.
       Now these pseudo arrays are written as single instances.
* Bugfix: GUI type support for QVariant.
       RBA/pya did not provide constructors for QVariant from 
       GUI types like QColor and QFont. These have been added now.
       The corresponding conversion functions to QColor, QFont etc.
       are provided as well.
* Bugfix: Problems with QVariant constructor: some feature were not
       usable. For example, a double value could not be passed to
       the constructor. Disambiguators have been provided to solve
       these issues.
* Enhancement: Cell/Category filter for marker browser. The marker
       browser now has a filter entry box to select specific cells
       or categories.
* Enhancement: Images are cached now for faster image update. 
       Specifically the "fit" image will be cached and if "fit" is 
       selected again, the image is restored rather quickly (provided
       the window is not resized). The cache depth can be configured 
       in "Setup/Display/Optimization".
* Bugfix: "Read all other layers" option in LEF/DEF reader was
       potentially assigning GDS layers which have been defined in
       the layer mapping. Now, layers used in the layer map for 
       targets are blocked and not used for automatic assignment.
* Enhancement: The database unit can be configured now in LEF/DEF
       import options. Previously it was fixed to 1 nm.
* Bugfix: RBA::LayerProperties#id was not always unique as stated
       by the documentation. Specifically not after a file was loaded.

-------------------------------------------------------------------
Mon Dec 28 19:51:00 UTC 2015 - matthias@koefferlein.de

- Update to 0.24.4

* Enhancement: Layer colors are iterated for named layers without
       layer numbers as well. Such layers are created when reading
       DXF files for example and all layers had the same color 
       initially. Now, these layers will be assigned different colors.
* Bugfix: RBA::TilingProcess#threads was not working properly 
       when assigning a value of 1.
* Bugfix: The perimeter computation now has changed to 64 bit numerics
       reducing the risk of numerical overflow. In earlier versions, 
       the perimeter computation of integer type shapes (polygons, 
       boxes, regions) was performed with 32 bit length which is 
       not sufficient to represent total perimeters of full layouts.
* Bugfix: The OASIS writer's S_TOP_CELL standard property now is 
       set to the correct value when using "Save cell as".
* Bugfix: Some patches are provided for enhanced compatibility with
       MacOS. One MacOS-only bug was related to a crash when re-registering
       of PCell's while developing then.
* Bugfix: PCell guiding shape parts could not be selected in partial
       editing mode using a drawn selection box.
* Enhancement: The color of the guiding shapes can now be configured
       individually.
* Bugfix: OASIS reader was not properly associating CELLNAME properties 
       with cells as the standard requires. Instead CELLNAME properties were
       ignored. 
* Bugfix: Strict mode compatibility issues in OASIS writer:
       File level PROPERTY records were not put right at the beginning of the file, 
       empty tables were not listed with 0 position, property value strings were
       not referenced by ID and the property modal variables were referenced 
       sometimes after name records (specifically CELLNAME with standard 
       properties enabled). According to the specification, the name records 
       reset these variables so this is not correct. Other readers may report 
       errors for such files.
* Enhancement: OASIS writer file size reduction. Now, the OASIS writer
       will opimize the arrangement of cell array instances so that 
       modal variables can be used for a better compaction.
* Enhancement: During script debugging now the Assistant window is active
       even while the debugger is executing a script. The main window is
       still inactive however to avoid fatal cross-interactions between 
       the debugger and the user interface.
* Bugfix: The Python PCell sample was broken.
* Bugfix: slowly bending paths have not been displayed correctly.
* Bugfix: coordinates might have been swapped in the box properties
       page when switching from local to absolute coordinates and 
       back.
* Bugfix: certain ruler styles with independent x and y axis have not
       been displayed properly when using a global transformation.
* Enhancement: the performance of "Flatten cell" is enhanced significantly
       in cases of many instances. 
* Bugfix: DRC output was producing new layers with an empty layer name
       selector (no major issue, but confusing).

-------------------------------------------------------------------
Thu Nov  5 20:22:49 UTC 2015 - matthias@koefferlein.de

- Update to 0.24.3

* Enhancement: PYTHONPATH does not mess up the Windows installation any
       longer. If you want to set the PYTHONPATH for KLayout, use 
       KLAYOUT_PYTHONPATH. 
* Bugfix: The oasis_write_std_properties attribute of RBA::SaveLayoutOptions
       did not work as described. To maintain backward compatibility and
       enable the cell bounding box feature, a new attribute called 
       oasis_write_cell_bounding_boxes was introduced.
* Bugfix: "Hide all" only hides the top level layer properties, not the
       members of layer groups.
* Bugfix: S_BOUNDING_BOX standard properties now appear after CELLNAME
       records in OASIS files as required by the OASIS specification.
* Bugfix: The unintuitive behavior of the "Writer Options" has been changed.
       Now, the writer options are applied to the saved layout always, not
       just on the first save. Previously, the program remembered the options
       and reused the previous options on following saves. This was quite
       unintuitive since changing the properties did not necessarily affect 
       the way files were written.
* Enhancement: The starting directory for files dialogs is the "Documents"
       folder on Windows now. Not the current directory which is the 
       installation directory usually.
* Bugfix: Signal names are property set for RBA::QListWidget and other 
       objects. This enables the use of "indexesChanged" signals and eliminates
       Qt runtime warnings.
* Bugfix: Library cells were not properly loaded again after reloading
       a layout which used libraries which itself referred to other libraries.
* Bugfix: The program crashed sometimes when using report databases with
       properties.
* Bugfix: Layers with a single box rendered wrong results in the DRC's 
       size function with strong undersize. The boxes did not vanish as
       expected but instead were inverted.
* Enhancement: The build now is compatible with Python 2.6.
* Bugfix: Reading OASIS files in strict mode with cell names consisting
       of a "$" character followed by an integer number (like "$1") sometimes
       messed up the cells.
* Bugfix: RBA::TilingProcessor could not be used both with tile size and
       tile count set since setting the tile size was resetting the tile
       count and vice versa.

-------------------------------------------------------------------
Sat Oct  3 16:25:21 UTC 2015 - matthias@koefferlein.de

- Update to 0.24.2

* Bugfix: Flip and Rotate function did not work as expected when the view 
       was descended into the hierarchy.
* Enhancement: RBA::BrowserDialog now also accepts a parent parameter
       which are important to better integrate such dialogs into the
       application.
* Bugfix/enhancement: "klayout_vo.exe" now is a pure viewer application
       again. By calling this executable, the edit functions cannot be
       enabled and the save functions are disabled as well. Under Linux,
       renaming the binary to "klayout_vo" switches KLayout into this
       mode as well.
* Bugfix: The zoom and selection rectangle can now be dragged outside the
       visible area and still define the zoom or selection rectangle.
* Bugfix: expressions were not coercing floating-point values consistently:
       The expression "to_i(2)+1.4" rendered 3 instead of 3.4 as expected.
       The sum was treated as an integer sum because the first operand is
       an integer. Now the integer is converted into a floating-point value
       as expected.

-------------------------------------------------------------------
Thu Aug 27 15:07:28 UTC 2015 - matthias@koefferlein.de

- Update to 0.24.1

* Enhancement: switched to -O2 instead of -O3 to avoid issues with certain
       gcc versions for which -O3 appears to be broken.
* Bugfix: fixed a backward compatibility issue in scripting. Specifically
       "view.each_object_selected { |s| s.shape }" will work again.
* Bugfix: the layer matching algorithm in the .lyp file layer assignment
       is compatible with the previous version again. This specifically applies
       to "wildcard" specifications. In 0.24, named and unnamed layers were 
       considered different even if GDS layer and datatype numbers were identical.
       The effect was that if a named layer was present, a .lyp file specification
       without that name was not matching the named layer and with "add other layers"
       the named layer was produced again.
* Enhancement: "Apply all" in the object properties dialog behaves somewhat
       more intuitive now. Specifically changing the path endcap styles now
       works as expected. For the other properties, a choice was provided 
       between applying changes in a relative or absolute way. For example,
       when the left edge of a box is changed, the left edges of all selected
       boxes are shifted by the same amount in relative mode. In absolute mode,
       the left edge will be set to the specified position for all selected boxes.
* Bugfix: Python iterators will keep a reference to the source object now. 
       This avoids problems when fetching iterated properties (typically "each..." methods)
       from short-living objects.
* Bugfix: Python's StopIteration exception does no longer appear in the debugger 
       now. This is an exception used internally to mark the end of an iteration 
       sequence.
* Bugfix: "Path#width=" does no longer reset the round end flag.
* Enhancement: the "Show All" mode of the marker browser is persisted now.

- Update to 0.24

* Enhancement: Python support: Scripts and PCells can now be coded in Python as well. Python and Ruby
       scripts may coexist in the same application and they can be debugged together. The macro
       IDE features a Python tab in which Python scripts can be managed. 
       The language features of Python and Ruby are very similar, so the features of the 
       integration are highly comparable and easy to translate. The Python module 
       name is "pya".
* Bugfix: When using a layer with special hierarchy level settings (i.e. #*), the ruler did not snap to that shapes.
* Bugfix: Qt item ownership is now transferred on some methods. For example, "QTreeWidget#insertItem" now will 
       transfer ownership of the item to the tree widget. Hence, when the variable holding the item goes out of scope,
       the tree item will not be destroyed.
* Enhancement: The shape selection can now be manipulated through scripts (new LayoutView methods "object_selection=",
       "select_object" etc.)
* Enhancement: New edge vs. region operations are supported (edge AND region and edge MINUS region)
* Enhancement: RBA/pya objects now in general feature a "_manage" and "_unmanage" method will allows releasing
       the ownership over an object in cases where object lifetime control is important (specifically when passing
       objects around in Qt applications).
* Enhancement: Many new RBA methods, i.e. 
       Annotation#id
       Cell#change_pcell_parameters
       Cell#pcell_parameters_by_name
       DPolygon#assign_hull (raw argument)

       SaveLayoutOptions#oasis_write_std_properties
       SaveLayoutOptions#oasis_write_std_properties=
       Shape#each_edge (with contour argument)
* Enhancement: Qt API is aligned better with C++ Qt notation. Several bug fixes, new features and stability enhancements.
       For example:
         New: RBA::Qt::white or RBA::Qt::GlobalColor::white
         Old: RBA::Qt_GlobalColor::white
* Enhancement: the debugger can now be disabled in the macro editor IDE for enhanced 
       script execution performance with IDE window open and less interactions between
       Qt code and Macro IDE
* Bugfix: DRC crashed when outputting shapes to a layer that was used as an input
       in further parts of the script but has been declared as input befor the layer
       was output.
* Bugfix: ".lyp wildcard replacement" now honors transformations as well
* Bugfix: Gerber import issues fixed: Zero-diameter circular apertures moves are translated into lines,
       Zero-length moves must not be clear for G1 and circular apertures.
* Bugfix: The technology button now applies the technology even if the technology did not change.
* Enhancement: Polygons with holes are better supported now (for example in partial editing). Such
       polygons cannot be written to GDS or OASIS (they will be converted to ones without holes), but
       they may be created in DRC scripts.
* Bugfix: "Reload layout" now doesn't forget the technology that was attached to a layout.
* Bugfix: Box side setters now behave more consistently in scripting. Before this fix, it was not possible to
       assign the sides of a box this way: "b = Box::new; b.left = 100; b.right = 300".
* Bugfix: recursive library references (library referencing itself indirectly) made the application
       crash.
* Bugfix: Subclass mapping sometimes failed in certain cases. This was particular annoying in Qt's event
       handlers since "QKeyEvent" (or similar classes) only showed up "QEvent".
* Enhancement: "Move selection to" function available in "Edit/Selection/Move To". With this function, 
       the selection (shapes are instances) can be moved to a specific position. You can specify the 
       reference point to use. For example the center of the bounding box.
* Bugfix: Menu icon assignment was not working in some cases within scripts.
* Bugfix: Readonly (global) macros could be edited but not saved.
* Bugfix: Instances could be selected even if they had only invalid layers.
* Enhancement: The application now features a crash handler. This handler gives some debugging information
       about the crash which you can send together with a bug report. In some cases, the crash handler will 
       allow continuing to work with the application although it's highly advisable to save and close.
* Bugfix: Registering plugins through the script's plugin API sometimes disabled view features.
* Bugfix: The macro IDE is not automatically put in the foreground any more. This sometimes interfered with
       modal dialogs shown from a macro.
* Enhancement: The macro IDE now features watch expressions which are automatically evaluated when in a
       breakpoint.
* Enhancements: The "Save Layout" options are now separated from the save function. That means they can 
       be configured once and the dialog will not pop up always when saving. This way, "Save All" is provided
       which will save all open files with the current options.
* Enhancement: A "Close All" function to close all open layouts.
* Enhancement: In scripted layout loads, multiple files can be loaded into the same layout object. In that
       case, the content of the files are merged. This worked so far with GDS. Now this also works with OASIS.
* Bugfix: OASIS int-typed properties now as written as such. Before, they have been written as strings.
* Enhancement: sizing code and path to polygon translation now will better maintain 45-degree edges.
* Enhancement: DRC support for edge/polygon booleans ("edges AND polygons" will select the edges inside the polygons,
       "edges MINUS polygons" will remove the edges inside the polygons)
* Enhancement: Global layout properties supported as well. Layout properties can be edited by selecting
       "User Properties" in "File/Layout Properties". They are written to OASIS. Writing to GDS2 is optional since
       that may create compatibility issues with other tools.
* Enhancement: The OASIS writer will now produce some standard properties: "S_TOP_CELL", "S_BOUNDING_BOX",
       "S_CELL_OFFSET", "S_MAX_SIGNED_INTEGER_WIDTH", "S_MAX_UNSIGNED_INTEGER_WIDTH" and "S_BOUNDING_BOXES_AVAILABLE".
* Enhancement: User properties of cells are available in cell context menu too: this way there can be 
       browsed in non-editable mode too. 
* Enhancement: "Degenerated" polygons (one or two points) can be created in scripts now when using "raw" mode.
       Such polygons are useful in the context of Minkowsky sums for example.
* Bugfix: The application crashed when the macro currently running was deleted.
* Enhancement: "Search & replace" now is available in viewer mode too, but without the ability to replace or
       delete.
* Enhancement: In menu paths, appending a "+" to the path means to add something after that item.
* Bugfix: Guiding shapes are only selected if the PCell corresponding to them is visible.
* Enhancement: there is a clearer indication now that 'Show layers without fill' is on.
* Enhancement: a new mode is available in which PCell content can be selected too. When editing things inside
       PCells however, PCell recomputation may revert these edits.
       The mode is found in "File/Setup", "Application/Selection" page.
* Enhancement: Edge set boolean operations have been too selective with respect to almost-parallel edges. 
       Now a tolerance is applied allowing edges to deviate by ~1 dbu.
* Enhancement: Search & replace: texts, paths and boxes are exported into report databases. 
       Shapes and instances are shown in micron coordinates and as seen in top.
* Enhancement: "Apply all" in properties dialogs: with this function, a specific change is applied to 
       all shapes or instances of the same class. For example a path width change is applied to all other selected 
       paths. The change will be applied smartly (hopefully), so that the intention of the change is preserved.
       For example a left edge shift for a box will be turned into the same shift for all other selected boxes.
* Enhancement: multiple categories can be selected in the marker browser now.
* Enhancement: the instance properties page now shows the cell dimensions (which are not editable of course).
* Enhancement: box property editing is less tedious - the left and right coordinates will now swap if the order
       changes and the mode (width/center or coordinates) is maintained.
* Enhancement: Report databases now support "tagged values" (values with a name) which are shown in the marker 
       list. The markers can be sorted by these values, provided they are string or numerical values. 
       RVE properties are read as tagged values.

Sat May 23 14:37:04 UTC 2015 - matthias@koefferlein.de

- Update to 0.23.11

* Bugfix: partial edit mode - a cell could be selected even if not visible
       With the new version, the selection behavior of normal selection
       and partial selection are somewhat more consistent.
* Bugfix: The CIF reader was not able to read CIF files with line breaks
       Commands with line breaks separating arguments were not read
       correctly.
* Bugfix: Printout now considers global transformation correctly
       Previously, the global transformation was ignored on printout
       and for screenshots.
* Enhancement: Partial edit mode now also supports polygons with holes
       Polygons with holes are rare since they cannot be represented
       in GDS or OASIS files. But they can be generated in DRC scripts.
       Now, such polygons can be edited in partial edit mode too.
* Bugfix: LEF/DEF reader now correctly uses half the path width for path extension
       Previously the default value was 0.
* Bugfix: Library update was not working properly for OASIS reader
       OASIS files with library references had as issue when updating
       the library cells: cell deleted in the library were not deleted
       in the layout.
* Enhancement: Warning, when drawing on invisible layers
       Previously there was not feedback: the shape was drawn, but not
       visible. Now, a warning pops up when trying to draw on invisible
       layers. This warning can be disabled.

-------------------------------------------------------------------
Mon Mar  9 20:02:10 UTC 2015 - matthias@koefferlein.de

- Update to 0.23.10

* Bugfix/Enhancement: CIF compatibility. The reader was not fully 
       compatible with the specification. For example, lower-case
       characters have not been ignored as specified. This has been
       fixed among other compatibility issues.
* Enhancement: The CIF writer now has an option to use blank characters
       as x/y separator. Some tools apparently don't like comma
       characters for separators (that is still the default).
* Enhancement: The CIF writer now has an option to emit dummy cell
       calls on top level to reference the top cells. The top-level
       entity is unnamed and does not correspond to a cell. Despite
       that some tools require these entities not to be empty and
       hold dummy references to the real top cells at least.
* Bugfix: Key bindings to default grid menu entries were not working
* Bugfix: When a layer was deleted and a shape on that layer was 
       selected, the application crashed
* Bugfix: Search and replace sometimes gave an internal error, for
       example with the following query:
       'with * do cell.name = "A" + cell.name'
* Bugfix: Search and replace was crashing when trying to delete 
       instances.
* Bugfix: Net tracer bug: the first selected shape was always taken as
       a whole even if parts were disabled through boolean NOT 
       operations.
* Bugfix: Net tracer was using the wrong origin when working in 
       "descend" mode.
* Bugfix/Enhancement: The technology setup now features "read all" and
       "add other layers" flags for the reader mapping table and 
       the layer properties. Before, the global flags were used
       causing some confusion. With the new options the behavior
       can be configured consistently.
* Enhancement: The file dialogs now remember the file type chosen.
* Bugfix: The application issues a error message when trying to 
       write very big images instead of crashing
* Enhancement: Two new Ruby methods to write image files. These new
       methods are LayoutView#save_image_with_options and LayoutView#
       get_image_with_options. These methods allow configuration of
       more features for the image generation like box to draw, 
       oversampling etc.
* Enhancement: DXF reader now converts ATTDEF entities to texts too.
* Bugfix: The application crashed when the top cell was deleted.

-------------------------------------------------------------------
Sat Jan 10 17:52:08 UTC 2015 - matthias@koefferlein.de

- Update to 0.23.9

* Bugfix: DEF reader: E and W pin orientation was swapped.
* Bugfix: DEF reader: PIN definitions are read correctly even if
       the PLACED statement comes before the LAYER statement.
* Enhancement: LEF reader: deprecated keyword TOPOPSTACKONLY is 
       ignored for VIA statements now instead of giving an error.
* Enhancement: DEF reader: the reader now is able to read BLOCKAGE
       definitions. Currently, routing and placement blockages are
       supported. The layers they appear on can be configured the 
       in the same fashion than for the other elements.
* Bugfix: Typing in the Macro Editor was slow if many macros were
       bound to menus.
* Enhancement: GDS AREF's with pitches not a multiple of the database
       unit are split into individual arrays rather than simply 
       rounding the pitch. The disadvantage of the rounding solution
       was an accumulation of rounding errors over the array instances
       leading to a substantial deviation from the target location.
* Bugfix: Paths have sometimes not been displayed properly, 
       specifically paths with a small segment length and sharp bends.
* Bugfix: DXF reader: bulges have not been ignored on the last vertex
       of a non-closed POLYLINE as they should.

-------------------------------------------------------------------
Sat Nov 15 22:51:55 UTC 2014 - matthias@koefferlein.de

- Update to 0.23.8

* Bugfix: DRC: "inside", "not_inside", "outside" and "not_outside" were
       broken
* Bugfix: LEF/DEF reader: VIA PATTERN support was broken
* Enhancement: LEF/DEF reader: Support for LEF/DEF Version 5.8 syntax
* Bugfix: The Tab order of certain dialogs was weired
* Bugfix: Multi-layout layer properties files in technology setups behaved
       strangely. Now, the behavior of layout properties files (.lyp) is
       the same in the technology context and the usual application context.

-------------------------------------------------------------------
Wed Oct 11 11:40:22 UTC 2014 - matthias@koefferlein.de

- Update to 0.23.7

* Bugfix: DRC was crashing on second run if it was overwriting an input file.
* Bugfix: RBA::InputDialog::ask_double was not accepting negative numbers.
* Bugfix: With a net highlighted in the net tracer, so view zoomed to show
       the whole net if a layer was shown or hidden.
* Bugfix: Ruler snapping was disabled for moderately complex hierarchies.
       The threshold has been increased. Now snapping of the ruler to objects
       also works for denser and more complex layouts.
* Bugfix: Some signals were not available to Ruby (i.e. QIODevice signals).
* Enhancement: When using "Hide empty layers", the layer list will scroll to 
       keep the selected layer visible (unless it is empty and hidden therefore).
* Enhancement: A "split view" for the cell trees. When multiple layouts are 
       loaded in a panel, you can choose split view (right mouse in cell list,
       check "Split View"). In split view, up to 5 cell trees are shown at the
       same time.

-------------------------------------------------------------------
Wed Aug 20 21:21:41 UTC 2014 - matthias@koefferlein.de

- Update to 0.23.6
 * Bugfix: A DRC issue was fixed. Sometimes errors were reported too many times.
           This happened for big polygons wrapping smaller ones.
 * Enhancement: Now, macro key bindings can be edited on the key binding page 
           of the setup dialog too if the macros are shown in the menu.
           Before, those changes were reset when the program was closed.
 * Enhancement: The DXF reader now also considers thin (width = 0) POLYLINES 
           as mergable edge contributions in the "merge edge" modes if the 
           POLYLINES are closed ones too.
 * Bugfix: The float function in the OASIS writer was fixed.
           This is a code cleanup, and did not have effect on functionality (yet).

-------------------------------------------------------------------
Sat Jul  5 20:22:40 UTC 2014 - matthias@koefferlein.de

- Update to 0.23.5
 * Bugfix: DXF polyline mode could not be set in reader options in Ruby. 
           A value of 3 and 4 was not allowed.
 * Enhancement: CIRCLE AND ELLIPSE objects are treated as thin lines in DXF reader's
           "merge edges" mode. Hence they participate in region formation.
 * Enhancement: A warning is displayed when an ambiguous keyboard shortcut is triggered
 * Bugfix: An assertion in the boolean processor was fixed.
 * Bugfix: The following command caused the program to crash on the Ruby console:
           "require 'net/http'; uri = URI('xyz')".
 * Bugfix: The "cell" function in DRC scripts was creating a new cell if is was not existing
           yet. In general, the DRC function is not supposed to change the layout's hierarchy.
 * Bugfix: The macro editor now can distinguish between the same file with different suffixes.
           Before, "test.rb" and "test.lym" were not presented as different files.
 * Enhancement: The marker browser now indicates if the number of markers exceeds the
           specified maximum and the list is shortened.
 * Bugfix: The "browser.rb" sample was not working any longer because of a backward
           compatibility issue.

-------------------------------------------------------------------
Sun Mar 16 08:37:30 UTC 2014 - matthias@koefferlein.de

- Update to 0.23.4
  * Bugfix: UTF8 encoding in XML was ignored - special characters have not been
    read properly. This in particular caused issues in the .lym macro files
    when UTF8 characters are employed.
  * Bugfix: Backward compatiblity issue: layout files with PCells written with 0.23
    could not be read with 0.22 and vice versa.
  * Bugfix: Label text centering and right-alignment was not working propertly
    with the default font.
  * Bugfix: A segmentation fault occuring when rerunning a PCell macro has been 
    fixed.
  * Bugfix: PCell layer parameters can be set to "no layer" now. This was possible
    before, but caused some issues - i.e. creation of dead layers.

-------------------------------------------------------------------
Mon Feb 24 08:18:01 UTC 2014 - burnus@net-b.de

- Update to 0.23.3
  * Bugfixes.
  * The net tracer now can be configured to auto-color the nets
    with a set of predefined colors.
  * The net tracer now has a "Redo" button which will trace all
    nets in the list again using the original start and stop
    (for path tracing) locations.

-------------------------------------------------------------------
Thu Jan 30 14:41:20 UTC 2014 - burnus@gmx.de

- Update to 0.23.2
  * Bug fixes.
  * Search & replace layer selection combo boxes now show display
    string
  * Unexpected elements are ignored in XML files.
  * Options are provided for making boolean operations not optimize
    the "single empty input" case for XOR tool and DRC (strict
    handling mode).

-------------------------------------------------------------------

  * Net tracer: Nets can now be colored individually.
  * The OASIS writer now uses CBLOCK compression also for tables.
  * Transparency is now supported for images.
  * "http:..." URLs are now allowed as file names - such files are
    loaded from the URL instead.
  * New command line options are available: "-nn" to load .lyt
    (technology file) on command line. "-b" for batch mode, "-zz"
    for display-less applications.
  * Cells can have properties now: Cells can now have user properties
    as well.
  * Transformations are now available for whole layout.
  * A function now is available to convert PCell's to normal (static)
     cells.

    copies of the child cells.
  * A "Tap" function is provided now.
  * There now is a function to convert instance arrays to single
    instances.
  * The instantiation path of an object is now shown in the status bar.
  * An option is now provided for configuring the replacement
    character for OASIS and GDS.
  * Some unicode support for texts in default font.
  * There is a GDS2 writer option now to eliminate zero-length paths.
  * There are new save options: disable or enable writing of
    PCell and library cell contexts, drop hidden cells.
  * Layers can now be made invalid.
  * Multi-selection on 'open layout' allows to open many files
    at once.
  * DRC functionality: a rich DRC engine was integrated in the tool
  * Search and replace feature plus custom queries.
  * Some enhancements on LEF/DEF import.
  * Auto-import feature for technologies.
  * RBA enhancements: Tiling processor, fill tool bindings,
    regions, edge collections, edge pairs and edge pair
    collections, numerous new methods and classes.
  * More configuration options for macro IDE.
  * The diff tool now has an option to disable smart cell matching
    and enable name-only cell matching.
  * cells can now be dragged and dropped from the cell list to the
    canvas.
  * Several smaller extensions and bug fixes.
