Version 4.4.58 release on 31/01/2016
-enhancement: instance names added to mosfets in extracted view
- bugfix: improved w/l extraction of MOS devices. Gates with jogs can still cause incorrect results however.

Version 4.4.59 release on 07/02/2016
- bugfix: Closing a window that was not the current window gave unpredicable results.
- enhancement: Flatten command can now be applied to selected instance(s) at the current level or at all levels for the instance(s).

Version 4.4.62 release on 25/02/2016
- enhancement: geomSize now supports a third optional parameter flags:
out_layer = geomSize(in_layer, size, flags)
If not specified it behaves as before i.e. all edges are sized by size. If flags are set to 'vertical' then sizing is only done in the vertical direction, if flags are set to 'horizontal' then sizing is only done in the horizontal direction.
- bugfix: For Linux systems, fixed a bug where OpenGL use could cause glade to quit or crash.
Version 4.4.63 release on 02/03/2016
- bugfix: reading a cellView with connectivity from a library did not set up instPins correctly
- bugfix: If an existing extracted view was present, running extraction would append to an existing cell. Now any existing extracted view is deleted and a new extracted view created.
- bugfix: Qt bug generated 2 keyevents when a bindkey pressed; Qt version updated from 5.4.1 to 5.5.1 to fix this. Affects e.g. the 'move' and 'copy' commands where 'x' flips the moving object in X, 'y' flips it in Y, and 'r' rotates it 90 degrees. Also if the techfile is set up correctly, 'u' and 'd' switch up/down a layer when entering a path.
- bugfix: moving to Qt 5.5 broke reading library layer colors for non-openGL display.
- bugfix: copying instances/arrays with magnification other than 1 set magnifiction of copied instance to 1.0

- enhancement: geomReportMarkers() function added. Takes a single boolean parameter (default true). If set to false, then DRC error markers are NOT reported for DRC functions that do not explicitly specify an error message. This allows them to be used to generate output layers without creating a violation marker.
- enhancement: Drawing a path will snap to instPins on starting and ending points; path net will be set to the instPin net and path width to the smaller side of the InstPin shape. Note that this will only work if the layer function of the instPin layer is set to ROUTING.
- bugfix: entering paths during edit in place gave incorrect coordinates.
- enhancement: First version of netlist driven layout enabled. Use the Tools->Netlist View to open a netlist window, then File->Open to read a Spice/CDL netlist. Privided PCells for the device names are loaded into a library, then you can create layout from the netlist, and cross-probe between netlist and layout views with full connectivity information. Full documentation will be added in the near future.

- enhancement: Hierarchy browser will select all instances of a cell if viewing cell hierarchy (rather than instance hierarchy)
- bugfix: GDS import/export ignores empty lines in mapfile.
- bugfix: import/export GDS with mapfile could crash if map table had empty entry.

- bugfix: fixed a bug where Create Instance dialog was getting duplicate cell names.
- bugfix: fixed a bug where Create Instance dialog was not updating default PCell properties when view name was changed.
Version 4.5.18 release on 23/12/2016
- bugfix: copying a label failed to copy its type, resulting in the copied label being a 'normal' label.
- enhancement: Schematic Check->CellView writes a property 'lastExtracted' to the schematic. And Export Netlist now checks for this property, and if it doesn't exist, or if the lastExtracted date/time is less than the schematic's last modified date/time, then an error is given and the netlist will not be written.
- enhancement: Schematic Check->CellView checks for duplicate instance names.
- bugfix: Copying e.g. a symbol did not copy pin shape connectivity, resulting in shapes having net info but no longer being pins.
- enhancement: Exporting a hierarchical netlist checks the top level cellView to see if it has any pins; if not, then no .subckt preamble/postamble is written.
- enhancement: added control of axes to schematic/symbols, separately from layout axes.
- enhancement: For schematics, when creating an instance of a symbol the instance properties are found by copying the symbol master's properties as defined by its labels with NLP expressions (which must have a default value). The property is created with the name/value of the default in the expression. FOr example a label on a mos symbol of the form [@w:w=%u:w=2.2u] will create a string property w with value "2.2u".
- enhancement: File->Export SVG command implemented for schematic/symbol editors. Dumps an SVG image of the display to a file. SVG (Scalable Vector Graphics) is, as its name implies, a vector format and so the image can be scaled without lines becoming 'fuzzy' due to pixel limitations of non-vector formats such as PNG, JPEG. SVG files can be viewed in most web browsers.
- enhancement: Property list editor for Create Instance and Query dialogs has been updated. Now allows adding, deleting and editing properties directly in the dialog.
- enhancement: Property list editor does basic type checking of values against property type and highlights errors.
- enhancement: Creating a wire in schematics will terminate wire if a subsequent click is on another wire, or on a pin.
Version 4.5.19 release on 30/12/2016

- bugfix: When query dialog open and property or net tab displayed, keep that tab as the current tab when selecting other objects.
- bugfix: Symbol editor Check->Current CellView did not clean up pin shapes for net correctly.
- bugfix: Schematic editor Check->Current CellView did not clean up instance name table correctly.
- bugfix: Export SVG did not set viewBox to current zoom window.
- enhancement: Library browser Copy Cell and Copy CellView now allow hierarchical copying of cells.
- bugfix: Copying cellViews preserves pin/net shape info.
