* Enhancement: %GITHUB%/issues/1514 Package manager: Support for Git-hosted packages
* Bugfix: %GITHUB%/issues/1512 "get_image" of LayoutView should also work on inactive views
* Bugfix: %GITHUB%/issues/1511 Typo
* Enhancement: %GITHUB%/issues/1510 Cross hair cursor
* Bugfix: %GITHUB%/issues/1503 Import LEF/DEF - LEF files given in list are ignored for DEF import
* Bugfix: %GITHUB%/issues/1499 strm2oas: support LAYER <layername> TYPE OVERLAP ; for L-shaped abstracts
* Bugfix: %GITHUB%/issues/1486 Invalid error "Some macros are configured to run automatically" when changing reader options
* Bugfix: %GITHUB%/issues/1485 Incorrectly set output cell name if using DRC::cell
* Bugfix: %GITHUB%/issues/1482 Strict mode oasis should write the S_CELL_OFFSET into the CELLNAME table
* Bugfix: %GITHUB%/issues/885 Must-connect checks in LVS
* Bugfix: -without-qt builds did not include DRC or LVS
* Enhancement: Added Layouterror_layer
* Enhancement: Option -k for copying log to a file
* Enhancement: Editor option to control snapping to grid while moving
This controls whether objects are snapped to grid (on) or moved in grid
increments (off)

* Bugfix: %GITHUB%/issues/1477 Macro IDE: changing the colors does not have an effect
* Bugfix: %GITHUB%/issues/1474 Throw a FATAL ERROR when multiple cellname have the same refnum
* Bugfix: %GITHUB%/issues/1473 Ignore 'Summarize missing layers' when sending XOR result to other layout)

* Bugfix: %GITHUB%/issues/1465 (maybe fixed) DRC crash at end of script
* Bugfix: %GITHUB%/issues/1464 Layoutget_info and Layoutset_info not longer segfault on wrong layer index
* Bugfix: %GITHUB%/issues/1460 CellRename dialog is larger now initially
* Enhancement: %GITHUB%/issues/1307 (partial) Produce UNPLACED macros if location is provided
* Enhancement: New aliases for inline operators (e.g. "+=") in RBA::Region and similar classes
Reasoning is that "+=" in Ruby is resolved into "+" and "=" which does not make
use of the inline optimization. Using "join_with" instead will avoid this. Other alias:
"join" for "+", "and" for "&", "and_with" for "&=", "not" for "-", "not_with" for "-=",
"or" for "|", "or_with" for "|=", "xor" for "^" and "xor_with" for "^=".

* Bugfix: Avoid a segfault in the properties dialog
* Enhancement: Crash log now is shown in a more reliable way - but less fancy.
In addition, a crash log is written 'klayout_crash.log' in the home path
and the crash message is printed to error.

* Enhancement: Package manager
- Do not update macros while installing: avoids transient error messages
- Offer to autorun macros also after package update (so far only on package new installation

when switching to the replace text box, focus was passed to the text editor instead
* Enhancement: CIF reader progress now functional

ends if edges overlap, graphical indicator for selected partial
- Wheel events do no longer change Combo Box selections
- DRC/LVS: log output overhead reduced for faster execution in
small layout cases
- Added RBA::Image/pya.Image constructor taking QImage and PixelBuffer
- Point objects are native citizens now of the database and act as
representatives for handles, better editing and visualization of
the latter
- Macro editor has "find previous" button now
- Mitigate the effect of overriding a globally-defined technology
with -nn on the command line by creating tech variants
- LEF/DEF map files now allow LEFPINNAME and PINNAME purpose to
map pin labels in a more consistent way
* Bugfix:
- Tilde expansion wasn't working for layout write
- Python specific API documentation did not mention disambiguation
for property/method ambiguity
- Python error messages are more readable and contain the exception
class
- PCell layer-type parameters did not work without a default value
- Point-like PCell handles now cannot be spoiled any longer in partial
mode
- "Duplicate" was also duplicating cells or layers depending on the
scope which was irritating. Now it's confined to geometry

- "report" wasn't working in DRC/LVS scripts for scripts only using
external sources
- Fixed a potential segfault on application exit

* Enhancement: New methods
- Layoutcopy_layer, Layoutmove_layer and Layoutclear_layer with shape type selector

* Enhancement: %GITHUB%/issues/1314 Storing (arbitrary) data in metadata
- Meta information can be attached to layout and cells
- Meta information has a string key and arbitrary value (hash, list supported)
- Optionally, meta information can be made persistent and
is stored in the (KLayout specific) context section of GDS2 and OASIS
- Meta information is shown in the user properties dialog, but is not editable
- Meta information is similar, but not the same than user properties

* Enhancement: Zoom In/Out menu functions now use the current mouse position for the zoom fixpoint (important when binding them to a key)
* Bugfix: More consistent behavior of RBA/pya: enum classes are properly made available (was for example RBA::Qt::Qt_Keys instead of RBA::Qt_Keys and pya.Qt.Keys was no fully initialized type object)
* Bugfix: Netlist reader: anonymous circuits (without definition) will not fail because of unknown parameters
* Bugfix: Closed paths lost last point after editing in partial edit mode
* Enhancement: Somewhat better grid snapping in partial edit mode
