# Changelog
## 2.1.2
### Fixed
- Fixed `LasHeader.update` (thus fixing `LasData.update_header`) computation of x,y,z mins and maxs
- Fixed regression introduced in 2.1.0 where changing the `header.scales` and/or `header.offsets`
on a `LasData` newly created and then setting `x` `y` or `z` would produce incorrect result.
## 2.1.1
### Fixed
- Fixed regression introduced in 2.1.0 where setting the x, y or z value would not properly set the corresponding
X, Y or Z value.
- Fixed `LasData.change_scaling` setting the header's `offsets` and/or `scales` to `None`
if the corresponding optionnal argument was not given to the `change_scaling` method.
The header will now correctly keep the corresponding value unchanged.
## 2.1.0
### Added
- Added a better error message when reading empty files
- Added a new `xyz` attribute to `LasData` that returns x, y, z as a new numpy array or sets the x, y, z from an array
- Added `LasData.remove_extra_dim` and `LasData.remove_extra_dims` to allow the removal of extra dimensions (__only__)
### Changed
- Minimum `lazrs` version updated to 0.4.0 to bring support for LAZ with variable size chunks
(used in [COPC](https://copc.io) files). the `laszip` backend already supported variable size chunks LAZ.
- Improved assigning to multiple dimensions at once (`las[['x', 'y', 'z']] = ...`)
- `laspy` will no longer raise encoding errors when reading files for which the header's `generating_software` or
`system_identifier` as well as the vlr's `description` is not `ascii` encoded as the spec mandates.
However, an encoding error will be raised when writing such files.
- `LasData.__getitem__` will now return a `LasData` when indexing with slice or numpy array.
`assert isinstance(las[[1, 2, 3, 4]], laspy.LasData)`
### Fixed
- Fix `PackedPointRecord.__len__` when array has no dim
- Fix scaled extra byte creation when the offsets/scales given to `ExtraBytesParam` where of type `list` or `tuple`
- Fix `ScaledArrayView` to allow indexing with `list` or `numpy.array`.
## Version 2.0.3
## Fixed
- Fix function that parses geotiff VLRs
- Fix handling of points with 'unregistered' extra bytes (PR #158)
- Fix to handle empty LAS/LAZ more robustly
## Version 2.0.2
### Changed
- Update minimum lazrs version which allows to:
- Fix Appending in LAZ files.
- Improve memory usage when reading/writing. (issue #152)
### Fixed
- Fix system_identifier reading by ignoring non ascii characters instead of erroring ,(issue #148, PR #149).
- Fix `LasData.change_scaling` method.
## Version 2.0.1
### Fixed
- Fix `.min` `.max` methods of array views
- Ship the tests as part of the source distribution (But they won't be installed with `pip install`)
## Version 2.0.0
- Overhaul of the internals by essentially incorporating pylas into laspy,
while the API to retrieve and set dimensions stayed the same, other parts changed
and will require adaptation.
- Better LAZ support
* Added support for writing LAZ
* Changed decompression mechanism by using either `laszip` python bindings (and not laszip-cli)
or `lazrs`
- Added ability to read and write LAS/LAS in `stream` / `chunked` mode.
- Changed laspy to support the reading and writing of LAS/LAZ data from and to `file-objects` and `bytes`
- Dropped support for python2.7, python3.6+ is supported.
