Descarteslabs

Added
- scenes.DLTile.assign(pad=...) method added to ease creation of a tile in all ways indentical except for the padding.

Changed
- The parameter nbits has been deprecated for catalog bands.

Workflows (channel v0-6) - Added
- New interactive map, with GUI controls for multiple layers, scaling, and colormaps.
- Colormaps for single-band images.
- Map interface displays errors that occur while the backend is rendering images.
- ImageCollection compositing no longer changes band names (red does not become red_mean, for example).
- .clip() and .scale() methods for Image/ImageCollection.
- Support specifying raster resampler method.
- Support specifying raster processing level: toa (top-of-atmosphere) or surface [surface reflectance).
- No more tiles 400s for missing data; missing/masked pixels can optionally be filled with a checkerboard pattern.

Workflows - Changed
- Workflows Image.concat renamed Image.concat_bands.
- Data are left in data_range values if physical_range is not set, instead of scaling to the range 0..1.
- Selecting the same band name twice (img.pick_bands("vv vv")) properly raises an error.
- Reduced DeprecationWarnings in Python 3.7.

Added
- Alpha Workflows API client has been added. Access to the Workflows backend is restricted; contact [support](https://descarteslabs.atlassian.net/servicedesk/customer/portals) for more information.
- Workflows support for Python 3 added in channel v0-5.

- Scenes API now supports band scaling and output type specification for rastering methods.
- Methods in the Metadata, Raster, and Vector service clients that accepted GeoJSON geometries
now also accept Shapely geometries.

Added
- Add support for user cython modules in tasks.

Changed
- Tasks webhook methods no longer require a group_id if a webhook id is provided.
- catalog_id property on images is no longer supported by the API
- Fix scenes.display handling of single band masked arrays with scalar masks
- Fix problems with incomplete UploadTask instances returned by vectors.FeatureCollection.list_uploads

Added
- Metadata, Catalog, and Scenes now support a new `storage_state` property for managing image metadata and filtering search results. `storage_state="available"` is the default for new images and indicates that the raster data for that scene is available on the Descartes Labs platform. `storage_state="remote"` indicates that the raster data has not yet been processed and made available to client users.
- The following additional colormaps are now supported for bands – 'cool', 'coolwarm', 'hot', 'bwr', 'gist_earth', 'terrain'. Find more details about the colormaps [here](https://matplotlib.org/gallery/color/colormap_reference.html).
- `Scene.ndarray`, `SceneCollection.stack`, and `SceneCollection.mosaic` now support passing a string as the `mask_alpha` argument to allow users to specify an alternate band name to use for masking.
- Scenes now supports a new `save_image` function that allows a user to save a visualization given a filename and extension.
- Tasks now allows you to unambiguously get a function by group id using `get_function_by_id`.
- All Client APIs now accept a `retries` argument to override the default retry configuration. The default remains
the same as the prior behavior, which is to attempt 3 retries on errors which can be retried.

Changed
- Bands of different but compatible types can now be rastered together in `Scene.ndarray()` and `Scene.download()` as well as across multiple scenes in `SceneCollection.mosaic()`, `SceneCollection.stack()` and `SceneCollection.download()`. The result will have the most general data type.
- Vector client functions that accept a `geometry` argument now support passing Shapely shapes in addition to GeoJSON.

Changed
- Removed deprecated method `Metadata.sources()`
- `FeatureCollection.filter(geometry)` will now raise an `InvalidQueryException` if you
try to overwrite an existing geometry in the filter chain. You can only set the
geometry once.
