Klayout

* "Synchonized views" and "Select top level only" configuration shortcuts
added to the "Views" menu.
* Gerber reader bugfixes and enhancements: less strict parsing of aperture
definitions, rotation of aperture macro elements is not considered
correctly. Enhanced drill file reader.
* Disabled cell copy & paste in viewer mode (was not working correctly).
* Bugfix: it was possible to create an invalid configuration when removing
all default stipples (lead to a crash on the next KLayout start).
* Bugfix: an error appeared when switching the tabs in the layer panel in
certain configuration involving groups.
* Correct initialization of ruby interpreter to support Ruby 1.9.2 and
later.
* Bugfix: marker browser was only partially reporting collected markers
for certain categories.
* XOR now has an option to make use of multiple cores using a configurable
number of threads.
* Bugfix: reset of configuration required a restart.
* Bugfix: OASIS reader now is more robust against overflow for g-deltas.
* GDS reader enhancement: An invalid angle (outside the range of -360 to
360 degree) now is no longer an error and the angle is automatically
restricted to the valid range.

* A bug in the clip function was fixed which was related to empty cells
(reported in the forum)
* By default, the first level of hierarchy is shown now if a new layout
is opened. That feature can be adjusted using the "Default levels of
hierarchy" setting on the "General" page in the setup dialog.
* For multiple top cells, the cell with the larges footprint is selected
initially.
* A simple print function (available in the "File" menu)
* Support for command 93 in CIF (AREF)
* Improved handling of single point paths. In particular with round ends.
They now render a circle in OASIS. In reverse, OASIS circles now render
single-point paths with round ends in GDS.
* Ruby scripts now work more reliably under ruby 1.9 (i.e. Windows binary).
Formerly, some operations failed due to improper initialization of the
encoding system (i.e. Dir.glob).
* Clean uninstaller under Windows (removes all registry entries).

* Bugfix: GDS2Text format was not recognized correctly in some cases.
* Texts: strings with line breaks can be edited now (line breaks are shown
as \n). Text size is shown more realistic now. Alignment flags are
supported in GDS2 and can be edited now.
* Layer and datatype is shown in addition to OASIS layer names in the layer
list. The old behaviour can be configured by unchecking the "Always show
layer and datatype" checkbox on the "Layers" page in the setup dialog.
* For most file dialogs, the specific filter is the default now (i.e.
"*.lyp" is default instead of "All files" for the layer properties file
dialogs.)
* There is a "all layout files" filter for the layout file selection dialogs.

* Bugfix: command line option -p was not working correctly.
* Bugfix: writing layouts with large coordinates was producing invalid OASIS
files in some cases.
* The tarkit now contains the files necessary for a build with Visual Studio
on Windows.

* Bugfix: content of cell was not shown correctly when the cell was moved.
* Bugfix: PCB import was not working properly (Bottom mounting mode was
broken, top cell and dbu were not set correctly when a PCB project file
was imported directly).
* Bugfix: RVE reader was not correctly handling check names with a dot.

* Bugfix: navigator was broken. It was not functional if KLayout was closed
with the navigator open.
